For installations where predictable temperature variations occur, the average material temperature shall be determined from – Item (a) or Item (b) as follows:

a) Across the wall of the pipe – the material temperature taken as the mean of the internal and external pipe surface temperatures, where a temperature differential exists between the fluid in the pipe and the external environ-mental. The pressure and temperature condition, where flow is stopped for prolonged periods, shall also be checked. In this event, fluid temperature and outside temperature may equalise.

b) With respect to time – the average temperature may be considered as the weighted average of temperatures for the proportion of time spent at each temperature under operational pressures.

The maximum measured mean wall temperature recorded is 35˚C on the top of the pipe during summer. Site specific conditions may influence and alter this reduction over black pipe which therefore Vinidex can not offer design guidelines.

Further reference should be sought from the design guidelines in the draft revision of AS 2033.

The pressure rating of PE pressure pipe shall be based on the temperature of the pipe wall, which may be determined from either:

a) an assumption of a constant pipe wall temperature typical for continuous service at a set temperature e.g. cold water service; or

b) the determination of an average service temperature where temperature variations are likely to occur in a predictable pattern eg. in cavity walls of roof spaces; or

c) the maximum service temperature less 10°C for installations where large unpredictable temperature variations occur up to a maximum of 80°C e.g. above-ground installations such as irrigation systems.

For Items (a) (b) and (c), the MAOP shall be in accordance with values in the above tables.

NOTE:

(i) The values tabled are for materials typically used in Australia/New Zealand.

(ii) The times given in years as (36y) are allowable extrapolation limits obtained by applying the factors in Table 1 of ISO 9080 to two years of test data at 80°C. Where appropriate, specific advice should be obtained from the manufacturer, and data provided shall be derived from testing to ISO 9080.

cOMPrESSED aIr SYSTEMS WOrkINg PrESSurE – PE 100

The following tables list maximum operating pressures in kPa. Under these conditions, the system life is expected to be in excess of 50 years.

For continuous operation at temperatures above 40˚C, life expectancy may be reduced. However, for normal operation, i.e. variable operating temperatures, system life would not be reduced, including operation for limited periods at temperatures up to 60˚C. Specific design data may be obtained from Vinidex.

System pressure capabilities have been derived using a safety factor of 2. The energy stored in compressed air and have the potential for pressure spikes means that the pressure rating is less than that for water, for which the safety factor is 1.25.

NOTE: Polyethylene pipe over PN6.3 can cope with full vacuum. Vacuum is described as zero pressure (minus one atmosphere).

The negative pressure has been calculated based upon immersion in water at 30˚C wall temperature. The pipe is assumed to have a 3% ovality.

As polyethylene is less dense than water, the pipe will float on the water surface. The end of the pipe should therefore be inverted to ensure the suction pipe is continuously full of water.

POLYEThYLENE fLaNgE cONNEcTIONS

Polyethylene stub flanges and backing rings are commonly used for connection to valves and pipe fittings. When designed and installed correctly they have proven to be a reliable jointing system which can be rated to the full pipeline pressure rating.

Stub flange Specification

The stub flange is butt welded to the pipe, hence it is important its wall thickness is the same as the pipe. It is therefore specified with the same PN and PE rating as the pipe.

Care should be taken when connecting onto wafer style butterfly valves with stub flanges. On some valves the mouth of the stub must be machined out slightly to allow full rotation of the butterfly plate when fully assembled. Where excessive material must be removed polyethylene tapered spacers must be used between the stub flange and the valve body.

Backing ring Specification

cOrrOSION PrOTEcTIONFlanges and fasteners should be plated in accordance with Australian standards or codes such as AS/NZS 4680 for galvanising. Alternatively, stainless steel flanges and fasteners can be used or flanges can be protected with polymeric coatings in accordance with AS/NZS 4158 and be used in conjunction with stainless steel fasteners.

MarkINgFlanges should be permanently and legibly marked with the flange designation and the manufacturers name, either on the rim or on the back of the flange between the rim and the pitch circle diameter.

TEMPEraTurE DEraTINgFor continuous operation at temperatures above 20° C, specific design data should be obtained from the pipe and fitting manufacturers.

gaSkETS The gasket material shall be suitable for the flange, the fluid and the environment. For specific requirements contact the manufacturer. For flanged joints intended for use with potable water the gasket material must comply with AS/NZS 4020.

SEaLSNatural rubber is generally resistant to most moderate chemicals wet or dry, Organic Acids, alcohols, Ketones and Aldehydes. It is generally not suitable for Ozone, Strong Acids, Fats, Oils, Greases,and most Hydrocarbons.

Ethylene Propylene Diene Monomer (EPDM) is generally resistant to Animal & Vegetable Oils, Ozone, Strong & Oxidising Chemicals. It is generally not resistant to Mineral Oils & Solvents, Aromatic Hydrocarbons.

Note: The pressure ratings of AS2129 cannot automatically be applied to PE stubs.

Stub flange and backing ring installation

Flanges must be installed correctly to ensure damage does not occur during operation. Incorrect installation is the most common cause of flange joint failure.

To avoid this, the following procedure should be used:

1. The flange should be assembled to the mating flange prior to welding the stub flange to the pipeline. If this is not practical the pipeline should be snaked a sufficient distance from the joint to ensure the stub can be brought squarely up to the mating flange.

2. The flange assembly must be lifted AT THE PIPE and BROUGHT SQUARELY UP TO TOUCH the mating flange PRIOR to bolting. Bringing the flanges into contact with the mating flange using the bolts will usually result in breakage of the stub during operation.

3. With the seal lined up, insert all bolts and tighten them until firm taking care not to damage the seal. Washers should be used under all bolt heads and nuts.

4. Tighten the bolts in the following sequence to the following torques. These torques apply for pressures up to 1000 kPa.

Specification recommendations

Unlike concrete pipe, polyethylene’s deflection transfers vertical soil and wheel loadings into the side fill. This deflection characteristic has proven to support the pipe under 30m of tailings dam fill quite successfully for many years.

The deflection of cement lined pipe is limited by the flexibility of the cement lining.

The design of a polyethylene pipe under soil and wheel loadings is specified in AS/NZS 2566.1 Buried Flexible Pipelines.

The performance of a flexible plastic under soil and wheel loadings will depend upon the following:

n Pipe Stiffness

n Soil Strength, Stiffness & Density

n Superimposed Wheel Loadings

n Trench Geometry

The pipe performance is particularly sensitive to soil strengths and levels of compaction.

Bedding material must consist of well graded particles in accordance with AS/NZS 2566.1.

Side support and pipe overlay material should be placed in nominal 80mm layers for pipe less than 250mm diameter and in nominal 150mm layers for pipe above 250mm diameter. Material compaction shall be completed as specified in accordance with design assumptions (AS/NZS 2566.1 details material types, density and resulting strengths). During placing, care must be taken to ensure adequate compaction of the material at the pipe haunches prior to placing overlay material.

The testing of compacted material density shall be completed in accordance with AS1289 5.1.1.


35


LIghT VEhIcLE rOaD PIPE crOSSINgS

Specification recommendations

Whilst Vinidex strongly recommends adherence to the Australian Standard AS2033 which recommends a minimum cover of 750mm for unsealed roads we also recognise that pipe crossings under light vehicle roads are frequently laid with a minimum of cover. If insufficient cover is provided the wheels may inpose directly onto the pipe resulting in localised buckling, of the pipe.

To avoid this buckling the wheel loadings must be distributed over the pipe. This may be achieved by applying a 250mm thick layer of compacted pavement over the pipe after thorough compaction of the side fill in layers to support the pipe.

A common method of achieving this compacted pavement is to use cement stabilized soil. This involves mixing a proportion of 2.5 bags of cement to one cubic metre of sand and compacting the mix in layers not thicker than 80mm for pipes less than 250mm and 150mm layers for pipe 250mm diameter and above.

The moisture content of the mixture shall be only sufficient to enable adequate mixing and placement of the material. Compact each layer with a minimum of four passes of a vibratory plate compactor which has a minimum static mass of 50 kilogram. Continue compaction to 95% of the Standard Maximum Dry Density of the material in accordance with AS1289.



36

aLLOWaBLE BENDINg raDIuS

Vinidex PE pipes are flexible in behaviour, and can be readily bent in the field.

In general terms, a minimum bending radius of 33 x outside diameter of the pipe (33 x DN) can be adopted for PE100 material pipes, whilst a radius of 20 x outside diameter of the pipe (20D) can be adopted for PE63, and PE80B material pipes during installation.

This flexibility enables PE pipes to accommodate uneven site conditions, and, by reducing the number of bends required, cuts down total job costs. For certain situations, the designer may wish to evaluate the resistance to kinking or the minimum bending radius arising from strain limitation. The long term strain from all sources should not exceed 0.04 (4%).

When bending pipes there are two control conditions:

1. Kinking in pipes with high SDR ratios.

2. High outer fibre strain in high pressure class pipes with low SDR ratios.

for condition 1

The minimum radius to prevent kinking (Rk) may be calculated by:

D (SDR-1)

1.12R

k = m

for condition 2

The minimum radius to prevent excess strain (Re) may be calculated by:

where

= outer fibre strain (maximum allowable = 0.04)

D = mean external diameter (m)

NOTE: These formulae do not incorporate any factor of safety. Kinking may occur suddenly and catastrophically and conservatism is advised. Care should be taken when bending pipes to ensure that the loading and support configuration produces the mode of bending and the radius of curvature expected.

crOSS-LINkED POLYEThYLENE IN PIPELINE aPPLIcaTIONS

abstract:

Cross-linked polyethylene (PE-X) is a material that has been in use for more than forty years in hot and cold plumbing and cable jacket applications, its resistance to high temperatures being utilized. More recently, other attributes, including resistance to slow crack growth (SCG) and rapid crack propagation (RCP) have facilitated development of PE-X for water, gas, mining and industrial applications.

cross-linked Polyethylene – What Is It?

Polyethylene consists of long chain molecules which are attracted through weak forces, known as van derWaal’s forces. The process of cross-linking sees adjacent molecular chains joined by strong covalent bonds at various positions. The result is a cross-linked three dimensional lattice, brought about by the fusion of amorphous and crystalline regions in the polyethylene.

Solid state polyethylene typically consists of amorphous and crystalline regions. The network resulting from the cross-linking process improves the mechanical performance of the material, resulting in significant increases in properties such as: thermal performance, slow crack growth, rapid crack propagation, impact resistance, tensile strength and abrasion resistance.

The inherent properties of cross-linked polyethylene are leading to exciting applications in water, gas, mining and industrial applications.

Jointing – Mechanical, Electrofusion, Butt fusion

As for polyethylene, mechanical and electrofusion fittings may be used for jointing. Butt fusion, however can only be used under certain criteria – prior to the polyethylene becoming cross linked or fusing standard polyethylene and fittings to cross linked pipe. Electrofusion is a suitable Jointing technique – PE100 couplings have shown to be successfully connect PE-X pipes, but where elevated temperature (>45oC) and long life (>50 years), other means of connection, such as mechanical fittings or Plasson PE-X electrofusion fittings, are required.

Further Jointing arrangements are currently under development.

application – Mining, Oil and gas

For the transport of abrasive slurries and fluids at elevated temperature, the outstanding abrasion resistance of PE-X makes it superior to PE, the usual material of choice, for this application.

PE-X may also be used a liner for steel pipes used for high pressure slurries, oil and gas pipelines. For high pressure oil and gas, PE and PA (nylon) have commonly been used, the latter due to the limited life of PE in these elevated temperature applications. The use of PE-X overcomes the limitations of PA and enables a more economic installation.

availability

Cross linked polyethylene pipe is manufactured especially for each project therefore consultation with your local Vinidex representative or office is required.

BOrE caSINg / PrESSurE PIPE (ScJ)

PVC pressure pipe is designed and used primarily to contain liquids under internal pressure – hence the classification system is based on pressure class designations. PVC pressure pipe is also legitimately used for other applications such as water bore casings. In this application, PVC pressure pipe is used to form the outside casing of a water bore drilled vertically down into the ground where the loads on the pipe are primarily external.

Historically, PVC-U has been successfully used as casing pipe but with the arrival of PVC-M and PVC-O there is a potential for inappropriate use of pipe because they may be in equivalent pressure classes (i.e. all PN12). If a pipe supplier is asked for a PVC-U PN12 pipe under most circumstances a PVC-M or PVC-O PN12 pipe can be substituted but not for bore casing applications. The key property of the pipe relevant to this application is stiffness and this is essentially a direct relationship to the pipe wall thickness, regardless of the PVC material type.

The reference document for water drilling contractors is the Minimum Construction Requirements for Water Bores in Australia (MCR) which specifies that all PVC bore casing pipe shall be PVC-U to AS1477 with the minimum casing diameter of 100mm. Hence this could be either Series 1 or Series 2 pipe. The actual size of the casing pipe is determined by the pump diameter and will be specified by the purchaser. The MCR nominates PN9 as the minimum pressure class to use for shallow low yield bores, and nominates PN12 pipe in all other cases.

Temperature considerations

Supermain™ pipes are de-rated for temperature according to the International practice for PVC based pipe materials as shown in the below table. Supermain™ pipes can be used for continuous service at temperatures up to 45°C. Higher temperatures should be avoided as Supermain ™will experience ‘reversion’ of the oriented structure at elevated temperatures, and may undergo significant dimensional distortion above 50°C.

The operating temperature above refers to the average across the wall. Short term exposure on one surface to temperatures in excess of the maximum operating temperature, such as may occur during storage can be tolerated. If extreme conditions are encountered for extended periods during pipe storage, some ovality may develop in the pipe or socket. This is of no consequence in the performance of the product and for jointing, Supermain pipes are readily re-rounded in making the joint.

If prolonged storage is expected, consideration should be given to shading the pipe with a material such as shade cloth or hessian, which does not concentrate the heat, placed so as to not restrict the circulation of air in the pipes, which has a cooling effect.

SuPErMaIN™ PVc-O

fatigue Design

Where a pipeline is to be subjected to a large number of cyclic or repetitive loads, fatigue design must be considered. For Supermain™ pipes, de-rating may be required if the total number of cycles in the pipe lifetime exceeds 30 000.

Lateral Loadings and Negative Pressures

The stiffness (lateral load for a given diametral deflection) is related to material modulus and the cube of the thickness. For PVC-O materials, the modulus is somewhat higher than that for standard PVC-U. However, the wall thickness is the overriding factor in determining the stiffness. Supermain™ pipes have a significantly lower stiffness than standard PVC-U pipes of the same pressure class. This is important in determining the response to lateral loading, due to soil and traffic, and negative pressures due to vacuum, ground water etc. In general water supply works with buried pipes at normal covers, lateral stiffness will not be a limiting design factor and will not require special consideration. For abnormal conditions, design should be conducted in accordance with AS/NZS 2566. Vinidex recommends the following values be used for the ring bending modulus for Supermain™ pipes:

Short Term Ring Bending Modulus at 20°C Eb 4000 MPa

Long Term Ring Bending Modulus at 20°C EbL 1800 MPa

Buckling may result if the pipe is subjected to internal vacuum, as a result of water hammer or siphonage. Other special cases include pump suction lines (with or without submersion) and concrete encasement.


71


SuPErMaIN™ PVc-O

Installation

Installation techniques for Supermain™ pipes are similar to that used for standard PVC-U pipes. The lower wall thickness and stiffness of PVC-O pipes compared to PVC-U pipes makes it essential that recommended practices for installation are adhered to and the pipe is fully supported.

Quality non cohesive material should be used for pipe bedding, side support and overlay. The pipe side support material should be placed evenly on both sides of the pipeline to two thirds the height of the pipe diameter and compacted by hand tamping. Side fill material should be worked under the sides of the pipe to eliminate all voids and provide maximum pipe haunching. The pipe overlay material should be levelled and compacted in layers to a minimum height of 150mm above the crown of the pipe or as specified.

The field testing procedures specified in AS2032 and the Vinidex Water Supply Manual should also be followed for Supermain™ pipelines except that the field test pressure should not exceed 1.25 times the pressure rating of the pipe.

Jointing

Supermain™ pipes are supplied with integral sockets for rubber ring jointing. The integral joints are capable of 1° deflection. Further deflection can be achieved using deflection couplings. Solvent cements should not be used with Supermain™ pipes.

fittings

A complete range of pipeline fittings is available for Supermain™ pipes to form a total pipeline system.

Jointing to Ductile Iron fittings

Supermain™ pipes may be jointed to ductile iron push fit and compression gasketed fittings. As with standard PVC-U, factory witness marks are not applicable when jointing to ductile iron fittings, and the spigots should be fully inserted to the stop. It is advisable before jointing to mark a witness line on the spigot at the appropriate length for the particular fitting so that full insertion can be observed.



72

SuPErMaIN™ PVc-O

Service connections

Service connections to Supermain pipes are made using a suitable tapping band complying with AS/NZS 4793 (Int) – Mechanical tapping bands for waterworks purposes and the following considerations:

n Holes should be drilled using a hole saw.

n Tapping bands having full circle support, an “O” or “V” seal, and positive stop against over-tightening are recommended for PVC-O pipes.

Vinidex does not recommend direct tapping of any PVC pipes, including Supermain™.

Ductile Iron fittings

Superlink™, Irrigation Bases, Hawle-A Valves.

DEEP SOckETS

The opportunity for socket withdrawal relies on a number of factors, chamfer length, squareness cut of pipe end, contraction due to temperature differential, poisson contraction of pipe when pressurised and how well the pipeline is constructed. There is much debate in the industry as to the appropriate value of each of these parameters, so the best way to insure against withdrawal is to use the biggest entry fittings available.

The Vinidex Superlink™ range has the deepest socket entry available in Australia, they are suitable for all pipe materials in all classes: Supermain™ PVC-O, Hydro™ PVC-M, modified PVC, PVC or ductile iron.

PVC pipes are lightweight and easy to handle and install. This section outlines the procedures for all aspects of below and above ground installation of PVC water supply pipe systems. Reference should also be made to AS 2032 – “Installation of PVC-U pipe systems”.

A number of water authorities require pipelayers to have participated in a training programme. The “Plastek” PVC Pipe installation programme, which was developed by TAFE and major water authorities in conjunction with Vinidex, is available through many TAFE colleges around Australia.

cuTTINg

During manufacture pipes are cut to standard length by cut-off saws. These saws have carbide-tipped circular blades which produce a neat cut without burrs.However, pipes may be cut on site with a variety of cutting tools. These are:

1. Proprietary cutting tools. These tools can cut, deburr and chamfer the pipe in one operation. They are the best tools for cutting pipe.

2. a portable electric circular saw with cut-off wheel. This is quick and easy to use and produces a neat clean cut requiring little deburring. It does, however, require a power supply and the operator has to be skilled in using it to produce a square cut.

3. a hand saw and mitre box. This saw produces a square cut but requires more deburring. It takes comparatively more time and effort and requires a stand. The use of roller cutters is not recommended.

Solvent cement Joints

Vinidex recommends Vinidex solvent cements and priming fluid for use with Vinidex PVC pipes and fittings, thus ensuring a complete quality system. Vinidex premium solvent cements and priming fluid are specially formulated for PVC pipes and fittings and should not be used with other thermoplastic materials. The following procedure should be strictly observed for best results. The steps and precautions will allow easy and efficient assembly of joints. Users may refer to AS/NZS 2032-1977 Code of practice for installation of PVC pipe systems for further guidance.

Incorrect procedure and short cuts will lead to poor quality joints and possible system failure.


77



SOLVENT cEMENT JOINTINg PrINcIPLES

Sockets on Vinidex pressure pipes and fittings for solvent cement joining are tapered, ensuring the right level of interference. This may not apply to all pipes and fittings, particularly from other countries.

Vinidex offers two types of solvent cements formulated specifically for pressure and non-pressure applications. They are colour coded, along with the primer, in accordance with AS/NZS 3879:

n Type ‘P’ for pressure, including potable water installations, designed to develop high shear strengths with an interference fit (green solvent, green print & lid).

n Type ‘N’ for non-pressure applications, designed for the higher gap filling properties needed for clearance fits (blue solvent, blue label & lid).

n Priming fluid for use with both solvent cements (red priming fluid, red label & lid).

Always use the correct solvent cement for the application. Solvent cement jointing is a ‘chemical welding’, not a gluing process. The priming fluid cleans, decreases and removes the glazed surface thus preparing and softening the surface of the pipe so that the solvent cement bonds the PVC.

The solvent cement softens, swells and dissolves the spigot and socket surfaces. These surfaces form a bond into one solid material as they cure.

rubber ring Joints

Jointing rings are supplied with the pipe, together with a lubricant suitable for the purpose. Other lubricants may not be suitable for potable water contact and may affect the ring. They should not be substituted without specific knowledge of these effects.

The ring provides a fluid seal in the socket of a pipe or fitting and is compressed when the spigot is passed into the socket. Check the label on the pipe socket. Series 1, Series 2, sewer rings or rings from other manufacturers cannot be interchanged. Sewer rings contain a root inhibitor and must not be used for potable water lines. These rings can be easily identified by their two coloured dots, pressure rings have only one coloured dot.

chaMfErINg

Vinidex PVC pipes for rubber ring jointing are supplied with a chamfered end. However, if a pipe which has been cut in the field is to be used for making a rubber ring joint, the spigot end must be chamfered. Special chamfering tools are available for this purpose, but in the absence of this equipment a body file can be used provided it does not leave any sharp edges which may cut the rubber ring. Do not make an excessively sharp edge at the rim of the bore and do not chip or break this edge. As a guide to the correct chamfer, the following table gives the length of chamfer required at 12° to 15° angle.

(a) SErIES 1 – SOckETED PIPE

When a pipe is cut, a witness mark should be pencilled in and care should be taken to mark the correct position in accordance with Table 4.1.

Where two witness mark positions are given, both should be marked on the pipe and the joint made so that one mark remains visible
