ASTM A335 Seamless P22 Ferritic Alloy Steel Boiler Pipe
YUHONG Group offers ASTM A335 / ASME SA335 P22 SMLS ferritic alloy steel pipes and we sell these pipes in many countries. This specification covers nominal wall and minimum wall seamless ferritic alloy-steel pipe intended for hightemperature service.
These pipes ordered to this specification shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding.
A335 P22 has good creep resistance. Creep is the tendency of a material to permanently deform under mechanical stress, especially at high temperatures, this feature ensures the long-term reliability of the pipeline under high temperature and high pressure conditions!
Besides, A335 P22 exhibits excellent strength at high temperatures, making it suitable for applications involving high temperature service conditions. It also has high corrosion resistance, so this is very important in applications where pipes are exposed to corrosive environments or fluids.
