About Conduits and Pipes

05.04.2010

I visited a pipe manufacturing factory today. Pipes are also called Conduits. Industrial pipes used in building sheds and other structures are called HR or CR Pipes. The pipes used in plunbing are G I Pipes. Seamless pipes are manufactured using extrusion technology from rods.

Steel Rolls are purchased from a steel plant and cut into rolls of thinner strips called Skelps. The skelps are then fed into a machine that curves and shaped. The curved pipes are directly fed into an Electric Resistant Welding Machine that automatically seals the seam inside. The Pipes are then cut into the required length and the external side is finished. Square pipes are formed by pressing the rounded and seamed pipes.
