Composite Piping System

We deal with top quality quality uPVC Pipes, SWR Pipes & Fittings, HDPE Pipes brings to you Composite Piping Systems. Composite Piping System is manufactured from high grade Virgin Polyethylene and Aluminium.

The Polymer is effectively bonded in the inside and outside of the Aluminium core by melt adhesive. This Aluminium Core is 100% leak proof for both liquids and gases making it an ideal pipe for transporting gases and liquids.

Where Kisan Composite Pipe is surface mounted, maximum support centers on straight runs should be 2.5 meters for Horizontal lines as well as Vertical lines. However, shorter support centers may be necessary in case the allowable sag is to be minimized.

Always support the fittings at all the joints.
Use proper clamps, preferably Kisan clamps, for supports.
Don't tighten the clamps too tight to avoid deformation of pipe section.
Don't use sharp objects such as nails and steel wires for holding the pipe.
