Manufacture:
The pipes are made by seamless or automatic welding process with no
addition of no of filler metal in the welding operation.
Heat treatment:
All seamless and welded pipes, other than Grades 8 and 11, are heat
treated to control their microstructure in accordance with methods
of:
· Normalizing
· Quenched and Tempered
· Double Normalized and Tempered
Tests and Inspection:
