Manufacturing Technique
Seamless pipe processing
Seamless pipe is the strongest among all pipes type as it has a homogeneous structure throughout the pipe length.In the Mandrel Mill pipe manufacturing process, the steel billet is heated to a high temperature in the rotary furnace. A cylindrical hollow is produced with the help of a rotary piercer and a set of roller arrangements that keeps the piercer at the center of the billet.
The outside diameter of the piercer is approximately that of the inside diameter of the finished pipe. With the help of a secondary roller arrangement, outside diameter and thickness are achieved.
Welded pipe processing
Welded Pipes are manufactured from Plate or continuous Coil or strips. A welded pipe can be manufactured in large sizes without any upper restriction. There are different welding methods used to weld the pipe.
* ERW- Electric Resistance Welding
* EFW- Electric Fusion Welding
* HFW- High-frequency welding
* SAW- Submerged Arc Welding (Long seam & Spiral Seam)
