uPvC Electrical Conduit & Duct System

Bending of Oman Therm uPvC Electrical Conduit Pipes

To bend circular conduit, insert the appropriate spring. The spring has an “eye” formed on one end, to which a cord should be attached in order to withdraw the spring. The bend is then made by hand or across the knee. Twice the angle required should be bent and the tube then allowed easing back to the desired position. Do not attempt to force the bend back with the spring inserted, as this action will damage the spring. When withdrawing the spring it is suggested that it be twisted in an anti-clockwise direction thus reducing the diameter of the spring and providing easy withdrawal. It is important to use the correct size spring. In cold weather it may be necessary to warm the tube slightly at the point where the bend is to be made. Always saddle the tubing as quickly as possible after bending.
