A312 pipe Manufacturing Types
ASTM A312 stainless steel pipe and tube covers following manufacturing types (Including hot finished or cold finished):
a. Seamless Pipe (SMLS): It covers stainless steel seamless pipe or tube in hot rolling or cold drawn.
b. Welded Pipe (WLD): Welded by an automatic welding process that does not add filler metal when welding.
c. Cold Worked Pipe (HCW pipe): The heavy cold-worked pipe that apply cold working of not less than 35% reduction in thickness of both wall, and welded to the welded pipe prior to final annealing. Do not use fillers during welding.
d. Welded and HCW pipe: Welded pipe and HCW pipe of 14 and smaller than NPS 14 shall have a single longitudinal weld. After approval by the purchaser, the welded pipe and HCW pipe with an NPS greater than NPS 14 shall have a single longitudinal weld or shall be manufactured by forming and welding two longitudinal sections of flat stock. So each welds are to be tested, inspected, inspected or treated.
Pipe Process of ASME SA312 316 Stainless Steel Seamless tube / ASTM A312 316 Stainless Steel Seamless Pipes
Round Bar → Inspection & Analysis → Cut to Length → Coutering → Peel → Heating → Perforation → Inspection of Size → Pickling → Inspection of Surface → Lubricating → Cold-Drawing(Cold-Rolling) → Degreasing → Annealing→ Straightening → Cut → Corp End Cutting off → Pickling/Passivating → Final Inspection( UT/ET TEST or Hydrostatic Test) → Marking → Packing → Shipping
