Electric Resistance Welded Pipe
Capital Star Steel SA uses the high frequency induction welding (HFI) process to manufacture pipes ranging in diameter from 219 mm (8 inch) to 610 mm (24 inch), and in various wall thicknesses.
In the ERW HFI manufacturing process, steel coil is mechanically formed into the required pipe diameter, after which a highfrequency electrical current is applied to heat the pipe to fuse the skelp to form a weld. Since no filler material is added, the weld joint becomes a homogeneous part of the completed pipe, thereby ensuring that the required engineering strength and performance specifications are met. See Table 2.
A completely smooth and high quality pipe is ensured via the process of removing the weld beads both internally and externally.
From raw material to finished pipe, the product undergoes the stringent international standard quality testing, thereby guaranteeing you the highest quality:
