PVC Pipes

• Rigid construction and a longer life span up to 25 years.
• The best alternative for G.I. Pipes and cost effective.
• Can be used for potable water supply.
• Special care is taken while fixing couplers with pipes to avoid column slippage.
• Specially designed square threads are capable of withstanding heavy load & these threads do not get corroded or deteriorated, even up to 25 years of use.
• Special rubber seal is provided at the end of threads to ensure 100% leak proof even at high pressure.
• A special rubber (EPDM & Nitrile) ring is provided in the coupling between the two pipes to absorb the vibration caused due to high pump pressure.
• Internal surface of these pipes are very smooth, resulting in very low head loss due to friction and increases water discharge up to maximum of 30%, compared with traditional G.I. pipes thereby saving power.
• Because of its light weight characteristic & special square thread design these pipes can be tightened easily by hand and no need of using pipe wrench.
• uPVC column pipes are resistant to chemical reactions when used in acidic or alkaline water assuring long life.
• Can handle water with maximum temperature up to 45 degrees Celsius.
• These pipes come in 3mm Standard length and are of light weight ensuring easy handling and storage.

[tab]CRI pipes are specially designed for submersible pumps, capable of handling both internal hydrostatic pressure as well as high tensile load caused by the pump weight and column water pressure and weight. In general, the first pipe fitted with the pump will be subjected to high hydrostatic pressure and the top-most one has to withstand the entire weight of the column water and pump.
The unique formulation used to in the manufacture of these pipes ensures that threads do not turn brittle , break or chip during the entire life cycle. the threading & dimension standards maintained make these pipes ideally suoitable for using as column pipes for submersible pumps worldwide.These pipes are produced in different types, which can be selected according to the installation requirements.[/tab]
