SWR/Drainage RPVC

Kasta Protech SWR Pipes and Fittings

The Soil, Waste, Rain water (SWR) Drainage system is an ideal solution for sewerage applications across rural and urban areas. Owing to its superior properties over costly and unhygienic conventional drainage systems, Kasta SWR Pipes and Fittings enable fast removal of waste without blockage and leakage. And its high impact strength, chemical and corrosion resistance, durability and zero maintenance makes it cost effective than other conventional drainage systems.

SWR Selfit Pipes

One end of the pipes and fittings is plain and the other end comes with a socket. The two ends can be easily joined by applying a coat of solvent cement which ensures a strong bonding at the joint. And makes it strong enough to withstand any adverse condition. These pipes and fittings are most suitable for buried and horizontal lines.

SWR Grooved Socket Pipes

One end of the pipe or fitting is plain and other end comes with grooved socket and a rubber ring. The two ends can be easily joined along with rubber ring with the help of rubber lubricant. This joint can withstand thermal expansion for the shaft or vertical lines. These pipes and fittings are more suitable and suggestible for shaft and vertical lines.
