Overview of ASTM A312 Seamless Stainless Steel Pipe

 

ASTM A312 grade covers standard stainless steel pipe grade. The ASTM A312 Pipe has alloying elements like chromium, nickel, copper, molybdenum, etc, which gives them excellent tolerance and resistance to corrosive and oxidative media across stress-induced setups. The versatile grade covers seamless, a range of heavily cold worked welded austenitic stainless steel and straight weld pipe modules. The ASTM A312 Schedule 40 Pipe is intended for use in high temperatures and is commonly seen in moderate pressure systems. The sch 40 pipe is a common schedule this pipe is available in the industry. The ASME SA12 Pipe is a pressurized vessel pipe grade designed for elevated pressure and temperature setups. These modules have good strength and don’t easily bend or distort in any circumstances.

ASTM A312 Pipe Manufacturing Types

l Seamless Pipe (SMLS): It covers stainless steel seamless pipe or tube in hot rolling or cold drawn.

l Welded Pipe (WLD): Welded by an automatic welding process that does not add filler metal when welding.

l 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.

l 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.
