Heavy Pressure solvent cemented pipes as per IS : 4985 - 2000
Pipes are available in metric series ranging from 20mm to 50mm, 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 pipe & fitting takes place creating a homogeneous joint.

BLUE & WHITE 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

  • Cutting the Pipe : Cut the pipe square with hand saw with suitable guide or by pipe cutter. Joint preparation. Chamfer or deburr pipe, approximately at 10o - 15 O Remove burrs form inside and outside diameters with a knife file or abrasive paper.
  • Test dry fit of the joint : Insert the pipe into the fitting and check that the interference occur about 1/3rd to 2/3rd of the socket depth. Too tight or too lose fitment may lead to leak, hence should be avoided.
  • Cleaning : Reamove any dirt, moisture or grease from pipe end & fitting sockets with a clean dry rag.
  • Application of Solvent Cement :Apply cement lightly but uniformly to inside of socket and outside of pipe and with a natural bristle nylon brush or suitable applicator. Apply a second coat of cement to the pipe end. Do not apply excessive cement in bell socket. Apply cement rapidly and be sure to completely cover all jointing surface area of the pipe and fittings.
  • Assembly of Joint : Immediately after applying the last coat of cement to the pipe (within 20 second) insert the male end of the pipe in the socket, giving pipe or fitting 1/4 turn to evenly distribute the cement. Remove excess cement from the pipe at the end of fitting socket. The joint must not be disturbed immediately after cementing. so that joint can properly cure. Allow cement to cure before pressurizing the system. Recommended curing time is 24 hours.

Advantages of PARAS Plumbing Pipes over GI Pipes :

  • Rust-Proof is the inherent property of PVC which ensures for constant Bore Diameter, that means uniform pressure on the pipe walls and no risk of puncture of pipe.
  • The Lightness of the Pipe makes it easy to Handle, during fitment, Installation, Transportation and Maintenance which is indirectly related to cost saving.
  • Smoothness of Bore supports the flow i.e. gives less resistance to flow which Increases the flow of Water.
  • Accuracy & Dimensional stability of 'PARAS' Plumbing pippes makes it leak proof at joints & Bends.
  • 'PARAS' plumbing pipes are Fire Resistant.
  • 'PARAS' plumbing pipes does not support rust formation, Fungus which gives longer life than normal GI Pipes.
  • Avoid forceful insertion of the pipe into the fitting.
  • Installation Pipelines should be straight and in 90o degree and always supported with pipe clips on specific intervals.
  • When the system is to be concealed ti should be pressure tested before concealment.
  • This system is not recommended for geyser outlets and hot water supply.
