- ERW (Electric Resistance Welding)
A process in which coils meeting the required product specifications are formed into the desired shape and welded along the strip edges using heat generated by electrical resistance or electromagnetic induction.
- A process that enhances corrosion resistance by applying a zinc coating to the surface of steel pipes.
- A process that heat-treats steel pipes to stabilize their metallurgical and improve material properties.
- A process that heat-treats steel pipes to improve their strength and toughness.
