CRI uPVC Borehole Column Pipe - 1½” Standard

(0 review)

Description 

 C.R.I. uPVC pipes are specially designed for submersible pumps and are capable of handling both internal hydrostatic pressure as well as high tensile load caused by the pump weight, cable weight & column water pressure & weight. PBTS (Polymer Bond Thread Sink) locking system is provided to avoid the loosening of coupler during the removal of pipes, a special polymer is injected into the threads via the coupler. The polymer forms a permanent bond between the coupler and pipe, thus nullifying any possibility of coupler loosening. Special rubber seal is provided at the end of the threads to ensure 100% leak proof joints even at high pressure. These pipes come in 3m standard length and are of light weight ensuring easy handling, storage & installation.

Features


  • Rigid construction & longer life span
  • Can be used for potable water supply.
  • Specially designed square threads are capable of withstanding heavy load and are corrosion free.
  • PBTS locking system: (Polymer Bond Thread Sink) To avoid the loosening of coupler during the removal of pipes, a special polymer is injected into the threads via the coupler. The polymer forms a permanent bond between the coupler and pipe, thus nullifying any possibility of coupler loosening.
  • Special rubber seal is provided at the end of threads to ensure 100% leak proof joints even at high pressure.
  • A special rubber (EPDM - High strand ) 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 30%, compared with traditional G.I. pipes, thereby saving power.
  • uPVC column pipes are resistant to chemical reactions when used in acidic or alkaline waters assuring long life.
  • Can handle water with maximum temperature up to 45°C.
  • These pipes come in 3m Standard length and are of light weight ensuring easy handling, storage and installation.

Application

Used as delivery pipe for bore well submersible pumps
