Sangio Pipe is a manufacturer and supplier of High and Low Density Polyethylene andPolypropylene extruded pipe. Our products enjoy widespread acceptance in CivilEngineering, Agricultural, Mining and Domestic applications.
Sangio Pipe is one of only 3 manufacturers countrywide who have been awarded SABSaccreditation for PE 100 pipe. There are even fewer who are able to provide the co-extruded colour identification stripes in their product. These are two stripes set 45o
apart along the entire length of the pipe and colour coded to indicate pipe type. Thishighly identifiable marking is a clear statement of total confidence in our product andis also of direct benefit to contractors. Selection of pipes for loading in a yard, orinspection of pipe in situ before trenches are closed, are made considerably easier bymeans of this colour identification.
Our SABS/ISO accredited pipes are manufactured at our Cato Ridge factory nearDurban and we provide a countrywide delivery service through our competent salesand distribution network.
Sangio Pipe employs in excess of 80 staff, predominantly from previously disadvantagedbackgrounds and we are committed to providing training and upliftment for our staff.

High density polyethylene pipe has been used extensively around the world sincethe 1950’s.The unique properties of High density polyethylene pipe have offered analternative to traditional material like steel and copper and also in non pressureapplications where clay and fibre cement pipes were used .
The material has been developed internationally from PE 80 to today's PE 100 materialwhich has shown a saving of approximately 30% on the wall thickness from the earlydays of Polyethylene. This mass saving relates back to a cost saving and a betterperformance as the internal diameter of the pipe is bigger. In many cases, becauseof the excellent flow characteristics of Polyethylene, pipes could be down sized whilestill performing within the expected parameters.
The pipes’ properties such as impact resistance and resistance to abrasion havemade HDPE pipe the obvious choice in the Mining and Industrial markets.
Piping made from polyethylene is a cost effective solution for a broad range of pipingapplications in the municipal, industrial, marine, mining, landfill, duct and agriculturalindustries. It has been tested and proven effective for above ground, surface, buried,slip-lined, floating and sub-surface marine applications.
High-density polyethylene pipe (HDPE) can carry potable water, wastewater, slurries,chemicals, hazardous wastes, and compressed gases. In fact, polyethylene pipe hasa long and distinguished history of service in the gas, oil, mining and other industries.It has the lowest repair frequency per kilometer of pipe per year compared with allother pressure pipe materials used for urban gas distribution.
Polyethylene is a strong, extremely tough, very durable product which offers longservice and trouble-free installation.
Aquaflow HDPE PressurePipe Systems
ApplicationsAquaflow High Density Polyethylene pressure pipes are specified with confidencein the following applications:
• Civil engineering. Water mains and reticulation systems• Building. House connections and cold water reticulation systems• Agriculture. Irrigation and water supply schemes• Industrial. Sewer effluent control and water purification. Conveyance of chemicals
and water in most industrial plants• Mining. Conveyance of water and air in underground operations. Used extensively
in treatment and recovery plants.
HDPE is generally used for high pressure applications ranging from 3.2 to 25 Bar,in conjunction with compression, buttweld or electrofusion fittings. Aquaflow HDPEpiping conforms to the SABS ISO 4427: 2008 specification.
QualityAquaflow HDPE pipe is manufactured to the relevant SABS and international qualityspecifications.

Polyethylene pressure pipe systemsoffer many advantages when comparedto traditional products, namely:
• Weather resistance in above ground applications
• Highly corrosion resistant• Ease of handling and installation,
exceptional toughness• Excellent abrasion resistance• Manufactured in long lengths and
coils• Manufactured to internationally
accepted standards• Service performance in excess of
50 years
Resistance to weatherdegradationThe high percentage of carbon blackin the formulation of the pipe rawmaterial enables HDPE pipe to resistdegradation by ultraviolet rays. Thepipe is impervious to rain and windconditions.
Chemical resistanceHDPE pipes are chemically inert butthere are some chemicals which couldaffect the pipe. As the product is alsonot electrically conductive, reactionscannot take place within the pipe andaffect its performance.
HDPE has excellent corrosionresistance and is virtually inert so itdoes not need expensive cathodicprotection. It offers better resistance tocorrosive acids, bases and salts thanmost piping materials and also hasgood resistance to many organicsubstances such as solvents and fuels.
Natural soil chemicals cannot degradethe pipe in any way.
Ease of handlingConventional materials are muchheavier than HDPE and will requirecranes and lifting gear. Handling of the
product can often be done by handallowing ease of installation in confinedspaces and difficult terrain.
High strength and flexibilityHDPE material has a high degree ofimpact resistance and is robust andductile. Pipes can bend quite easilyallowing for savings in design as lesscritical angle changes can be madewithout bends. HDPE pipe can be laidacross uneven surfaces and in narrowtrenches. Pipe can be joined outsideof the trench before installation into thetrench. The ability to absorb pressuresurges makes the product superior toother plastic pipe materials.
Even in sub zero temperatures HDPEcan still perform to expectation.
Resistance to abrasionWhere very abrasive mediums have tobe transported HDPE has proved itselfto be the pipe product of choice. HDPEoutperforms traditional pipe materialssuch as steel and steel with sacrificiallayers (rubber lined steel).
The product is used extensively in minetailings and washing plants.
Co-efficient of frictionThe smooth internal surface of the pipeand the impermeability of HDPE allowsa greater flow capacity and minimalfriction loss. It has less drag and a lowertendency for turbulance at high velocity.Its superior chemical resistance andnon-stick surface combines to eliminatescaling and pitting. This preserves theexcellent hydraulic characteristicsthroughout the pipe’s service life.
When designing pipelines, use theHazen-Williams C factor of 150 and ann factor of 0.009, when using theManning formula.

The SABS 533 specification has been superceded in partby the adoption of the SABS ISO 4427 of 1996 for HDPEpipe systems.
The following table shows which specifications are currentlyapplicable for LDPE and HDPE pipe systems:
Notes:• The HDPE pipe dimensions and pressure classes in
the SABS ISO 4427 specification remain unchangedwhen compared to the SABS 533: Parts 2 and 3 specification, except where calculated in terms of ISO 4065.
• The adoption of the ISO 4427 specification has resultedin the change of notation for HDPE piping from TypesIV and V to PE 63 and 80. The 63, 80 and 100 refer to various grades of HDPE polymer and their designstresses.
• The SABS 533: Part 1 specification remains in forceand is applicable to LDPE systems only.

Specifications
HDPE PE 80 (Type V) is based on a design stress valueof 6.3MPa, which results in the manufacturing of pipe witha thinner wall, and consequently greater ID than the PE63 (Type IV) specification. This results in material savingsand improved flow characteristics.
HDPE PE 100 pipe is based on a design stress value of8.0MPa, which results in an even thinner pipe wall thicknessthan PE 80 pipe due to the higher grade of material.

Codes of PracticeHandlingPipes manufactured in HDPE are strong, durable and easy-to-handle. In commonwith most construction materials, they should nevertheless be handled with careto avoid damage being caused to the pipes.
StoragePipes should be stored on level, flat ground, free of stones or sharp protrusions.The height of the stacked pipe should not exceed 5 coils. Normal exposure todirect sunl ight during the contract wi l l not damage the pipe.
CuttingCarefully cut the pipe ends square using a fine-toothed hand saw. Remove burrsand cutting debris.
JointingCompression fittingsClean the pipe end, lightly lubricate both the interior of the fittings and the pipeend. Slacken the nut and insert the pipe fully into the fitting. Tighten the nut -hand tight and a quarter turn with a strap wrench or nut spanner. NOTE: Do notovert ighten. Overt ightening may cause the assembly to leak.
Buttweld and Electrofusion fittingsButtweld and electrofusion fittings have a separate set of jointing instructions. Ensurethat you obtain and follow the specific information when you purchase them.
