Seamless steel tubes for pressure purposes
Part 1: Non-alloy steel tubes with specified room temperature properties
Part 2: Non-alloy and alloy steel tubes with specified elevated temperature properties
Purpose: For the boiler pipes, tobacco pipes, superheater tubes, air preheatertubes.
The main production steel grades:
P195, P235, P265, P195GH, P235GH, P265GH, 13CrMo4-5, 10CrMo9-10 and so on.
Following consultations, can also be supply other grades of steel pipe.
