Manufacturing Technique
Seamless Pipe Process
A solid round billet is formed into a tube shell by rotary perforation.
The pipe shell is further reduced to specified dimensions by the stretch mill. The pipes then are conveyed to the cutoff mechanism, where they are cut to the prescribed length. then these pipes are bundled and directed to subsequent finishing and inspection operations before shipment.
Welded Pipe Process
In the Electric Resistance Welding (ERW) process, a flat sheet of steel is cold-formed into a cylindrical shape to manufacture pipe. Then current is applied to either edge of the steel cylinder, and the steel is heated to the point that the edges forcibly form a bond without welding filler material.

3)To avoid scratches,after polishing,the tubes will be lay out on a steel crate then we could lift the whole steel crate instead
of the tube.
4)On the other hand, we use the gunny bags to protect the tube's surface when the tube laying-out.
5. How do you inspect the tubes?
The Quality inspectors inspect the tubes during each production processes from raw material,tube welding,polishing,packaging.
