22'' 559mm OD Hot Rolled Steel Pipe , Standard Hardened Steel Pipe
Heavy Wall Thickness
New Force supplies full grade and range of ASTM A335 alloy steel
pipe, with main grades of P11, P12, P22,P9, suitable for high
temperature 610ºC, used as main steam pipe for power plant, super
heater and reheater for heat resistant and good processing
performance.
ASTM A335 specification covers nominal wall and minimum wall
seamless ferritic alloy-steel pipe intended for high-temperature
service. Pipe and tube ordered to this specification shall be
suitable for bending, flanging, and similar forming operations, and
for fusion welding.
