PLUMBING PIPE MATERIALS

A Vision To Clear Solutions.

Pipe material

·         Cast iron – no corrosive waste/

·         Reinforced concrete

·         Mild steel tube – screwed and flanged

·         Copper – light weight easy to install

·         Brass

·         Wrought iron- screwed and flanged

·         Asbestos cement pipe – above ground

·         Lead – where small size and lengthy more at urinals/ cost is high

·         Polythene and poly vinyl chloride

·         GRP –glass reinforced plastic

·         MDPE – medium density polyethylene pipe

·         Acrylonitrile butadiene styrene

·         Ductile iron pipe

Standard as per code

·         Cast iron, vertically cast or centrifugally (spun) cast ( see IS :1.536-1976$ and IS : 1537-1976s;

·         Steel (lined or coated with bitumen or bituminous composition and out-coated with cement concrete or mortar, where necessary) (IS: 1916-196311 and IS: 3589196611);

·         Reinforced concrete (IS : 458-1971** )

·         Prestressed concrete (IS : 784-1978* );

·         Mild steel tubes or tubular (galvanized) [ see IS : 1239 ( Part 1 )-19797 1;

·         Copper (IS : 1545-19823 );

·         Brass (IS : 407-19815 );

·         Wrought iron;

·         Asbestos cement (IS : 1626196011 and IS : 1592-1980);

·         Lead [IS : 404 ( Part 1 )-1977- 1

·         Polyethylene (IS : 3076-1968fi ) and ( IS : 4984-1978); and

·         Un plasticized PVC pipes (IS : 4985-1981 ).

In choosing the material for piping and fittings, account shall be taken of the character of the water to be conveyed through it, the nature of the ground in which the piping is to be laid and the relative cost as compared with its useful life. The material shall be resistant to corrosion, both inside and outside or shall be suitably protected against corrosion.

Copper piping may be used particularly in hot water installations provided water is not capable of dissolving an undue amount of copper. Asbestos cement pipes may be used; however, adequate should be taken while laying backfilling (IS : 6530-1972)Mild steel tubes used in plumbing system shall be of medium class Conforming to IS: 1239 (Part 1)-1979

Polythene pipes and PVC pipes should not be laid on hot surfaces or in too close a proximity of hot water pipes. Care should also be taken to avoid locations where they are likely to be exposed to atmospheres charged with coal gas [ see IS : 7634 ( Part 2 )-1975t and IS : 7634 ( Part 3 )-1975f 1.
