SPECIFICATION FOR DETACHABLE JOINTS AND VARIABLE

ADAPTORS FOR DI, uPVC AND AC PIPES 1.0 General

1.1 This specification is applicable to all Detachable Joints and Variable Adaptors for

water supply piping system and shall be read together with JKR 20200-0045-99,

Standard Specification for Detachable Joints And Variable Adaptor for DI, uPVC & AC

Pipes.

1.2 This specification will provide necessary information on the product dimension and

requirements for the supply of joints only.

2.0 Type of Detachable Joint

Type, design and sizes for Detachable Joint as per drawing.

3.0 Type of Variable Adaptor

3.1 Type A : Variable Adaptor to suit asbestos cement complying to MS 712 and cement

lined mild steel pipes complying with JKR Standard.

4.0 Working Pressure

The fitting covered by this specification shall be of working pressure as stated in the table

below:

Type Class Nominal Size Working Pressure

Type A 25 DN 80 – 600 16.0 bar

Type B Mono Class DN 80 – 300 16.0 bar

Type C K12 DN 100 – 300 25.0 bar

DN 350 – 600 16.0 bar

Type D - DN 80 - 600 16.0 bar

6.0 Effect of Non – metallic Products on Water Quality

When used under the conditions for which they are designed, non – metallic products in contact with or likely to come into contact with potable water shall comply with BS 6920 Part 1 : 1990.

7.0 Casting

All casting shall be homogeneous, smooth and shall be free from flaws, cracks, blow

holes, cuts or other harmful defects. All surfaces in close proximity to the pipe and

gaskets shall be smooth and free sharp edge.

8.0 Dimensions and Tolerances

Detachable joints of various nominal sizes shall fit respective AC, uPVC and ductile

iron pipes of same nominal sizes. Joints tolerance of plus 1/50 nominal diameter shall

be allowed for easy assembly. 9.0 Sleeve

Dimensions may differ from one manufacturer to another. For the range of nominal

sizes from 50mm to 600mm for each pipe material, dimensions shall be in accordance

to the specification requirement describe in Table 1 to 4.




10.0 Flange

Flanges shall be machined and drilled in accordance with BS 4504: Part 3.2, for working

pressure of PN 16. For nominal pipe sizes in the range 50mm to 600mm the dimensions of

variable adaptor shall be in accordance with Table 3 to 8.

11.0 Bolts, Stud, Nuts and Washers.

a) Bolts shall be provided with a track head, which locates in a similarly shaped hole in the

end ring, thus preventing rotation of the bolt and permitting tightening of the bolts using

only one spanner.

b) The treads on bolts, studs and nuts shall comply with ISO metric series of BS 3643 Part Threads lengths shall in every case be of sufficient length to permit proper tightening of

the joints or variable adaptor to create the designed pressure seal without the nut

reaching the end of the threaded section. 12.0 Gasket

Gasket shall be free from porous areas, foreign materials and visible defects. Reclaimed

rubber shall not be used.

Gasket shall be such size and shape as to provide a pressure tight seal for the expectancy of

the pipeline under the specified working, transient and test pressure conditions.

13.0 Protection Against Corrosion

Detachable Joint and Variable Adaptor shall be protected against corrosion externally and

internally by Fusion Bonded Epoxy powder

FBE thickness shall be uniformly between 250µm to 350µm.

14.0 Sampling

Sampling method shall comply with the minimum sampling requirement and any failure to the

test piece will render the whole batch to be rejected.

15.0 Protection against damage in Storage, Transport and Handling

Detachable joint and variable adaptor shall be protected against damage in storage, transport

and handling by means of individual paper boxes and plastic-wrapped in batch of tens.




16.0 Tests and Inspection

a. All tests and inspection will be carried out in accordance to the specification.

b. It the responsibility of the Supplier to inform SAJ when the goods are being manufactured

for inspection and testing prior to delivery, by which, failing to will allow SAJ reserves the

right to refuse delivery.

c. Tests shall be carried out in the premise of the supplier with all apparatus and equipment

required be made available to perform all tests.

d. Minimum of 10 percent of the fittings supplied will be tested prior to delivery. Any test,

which fails, will render the whole batch rejected.

e. The supplier shall deem to have included all costs for inspection and testing either done

by SAJ or independent body appointed by SAJ.

f. At any time, when requested, the supplier shall provide SAJ a sample of the product

offered for evaluation purposes. All costs shall be borne by the supplier.

g. If at any time the supplier fails to deliver the required sample, the product is deemed fail to

meet the specifications.

17. Certification

a. Manufacturer and/or supplier are required to provide a copy of the certificate and testing

report from SIRIM, IKRAM or other recognised certification body.

b. Tests report required should be those tests conducted within a year period.

c. SAJ have the right to refuse offer or reject supply if the documents required are not

enclosed.

18. Packing

All Detachable Joints and Variable Adaptors shall be individually packed with proper methods

and protected from damage during transit.

19. Markings

All joints supplied shall embody the following markings: -

a) Body material – ‘DI’ b) Nominal Size c) Class/working pressure (PN) d) Joint type, pipe type to be connected at each end, year manufactured. e) Gasket markings – manufacturer, size, and mould number, material grade

and code used. f) Manufacturer’s name or trade mark g) Year of manufacture (last two digit) h) Lettering “SAJ”




20. Pre – delivery inspection

a. It is the responsibility of the tenderer to inform SAJ for inspection purposes during

manufacturing and before delivery. SAJ reserve the right to inspect and witness the

testing of product offered.
