Pressure Pipes

The selfit (Solvent Cement joint) pipes have one end self-socketed and the other and plain, which fits snugly without the use of couplers. The strong solvent cement joint is permanent and trouble-free

RANGE

Selfit pipes are manufactured in the range of 25 mm to 315 mm diameters in 2.5, 4, 6, 8, 10 and 12.5 kgf/cm2 working pressure.

Advantage:

  • Selfit sockets are formed with high precision on specially developed sophisticated machines.
  • 50% saving in installation time, as compared with plain ended pipes and loose couplers.
  • The number of joints is reduced by 50% resulting in substantial saving in labor costs.
  • The requirement of Solvent Cement for a pipeline is reduced by almost 50%.
  • Cost less than conventional plain ended pipes with loose couplers.
  • Eliminates the inconvenience of loose couplers, and reduction in inventory costs.
  • Plain pipes are available in 315 mm diameter in 2.5, 4, 6 and 10 kgf/cm2 working pressure.
  • Selfit pipes are supplied in standard length of 6 meters exclusive of the socket portion.

    Note 1. - The table is based on metric series of pipe dimensions given in ISO 161/1 in respect of pipe dimensions and ISO DIS 4422.
    Note 2. - The wall thickness of pipe is based on a safe working stress of 8.6 Map at 270C. The working pressure gets reduced at sustained higher temperatures. Occasional rise in temperature, as in summer, with concurrent corresponding reduction in temperature during nights has no deleterious effect on the working pressure of the pipes considering the total life of pipe.




Heavy Pressure Solvent Cemented Pipes (As Per Is 4985: 2000)


Pipes are available in metric series ranging from 20mm to 50 mm, in a standard length of 6 meters, plain at both the ends. These pipes are joined by use of solvent cement in which mating & fusion between the pipes & fitting takes place creating a homogenous joint. The pipes are in Grey colour & the fittings are dark grey in colour.

ASTM Heavy Pressure Pipes

UV Stabilised Blue & White plumbing pipes are available in sizes from ½” to 4: in Schedule 40 & Schedule 80 series as per ASTM D 1785 standards. These pipes are available in standard length of 3 meters & 6mtrs.

Blue Threaded Pipes

These pipes are threaded at both the ends with threads as per IS 554, BSPT. These pipes can be used in combination with G.I. fittings readily available in the market.

White Plain Ended Pipes

These pipes are plain at both ends and can be joined with PVC fittings available in white colour. The joint formed between the pipes & fitting with the help of solvent cement is a permanent homogenous joint.

Advantages over conventional G.I. piping systems

Low transportation cost Ease of handling Lower material & installation cost PVC-U pipe has a smooth surface, which reduces pressure losses and thus conserves electrical energy High corrosion resistance, durable. The solvent cement joints are leak proof and the joint is as strong as the parent material. The joints are tested under pressure as stipulated in the standard. The lengths can be cut to required measurement and joined easily without laborious threading operation.
