uPVC Elastomeric Seal Ring Fit Pipes

(IS:4985-2000)

CONSTRUCTION: This pipe is made of un-plastisized poly vinyl chloride (uPVC).

It is a versatile plastic having an excellent combination of strength, chemical inertness and fine resistance, which gives optimum performance at very low and high temperatures like less than 00 to 500.

ADVANTAGES:

  • Reliable leak proof joints.
  • Can absorb linear expansion and contraction.
  • Easy and convenient installation. No need of solvent cement.
  • Corrosion, Chemical and Biological resistant. Ensure pure water flow.
  • Cab be tested immediately after installation. Saves pipe line commissioning time.
  • Flexible. Can accommodate slight soil movement and also tolerate small gradients.
  • Smoother bore in comparison to Cement and GI pipes, which allows free flow of water.
  • Light weight reduces the transportation cost, installation cost and handling costs.
  • Seamless strong and resilient.

Notes:

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.

2. The wall thickness of pipes are based on a safe working stress of 8.6 MPa at 270C and the working pressure gets reduced at sustained higher temperatures.

Occasional rise in temperature as in summer seasion with concurrent corresponding reduction in temperature during nights has no deleterious effect on the life working pressure of the pipes considering the total life of the pipes.

Applications : For water lines and sewer line in infrastructure work, for disposal of garbage and for irrigation.

Product Range : Available in sizes of outer Dia 63 mm to 315 mm in pressure rating of 2.5 kg/cm2, 4 kg/cm2, 6 kg/cm2, 8 kg/cm2, 10 kg/cm2, 12.5 kg/cm2.

Specifications : Confirming to IS:4985:2000 with rubber ring joint as per ISO 4422 or DIN 8062 or IS:5382-85.

Installation Procedure :
1. Spigot end is provided with 150 chamfer for full length pipe. It cut lengths are to be used, then deburr the spigot end after cutting at site and provide 150 chamfer, using file.
2. Mark insertion depth on spigot.
3. Clean the socket and ensure that elastomeric sealing ring is properly installed in it's grove without twist.
4. Apply lubricant on the spigot.
5. Slide the spigot into socket thus compressing the sealing lips. In case of large diameter of pipes, use pipe jack.
