ASTM A335 alloy steel pipe

ASTM A335 seamless ferritic alloy-steel pipe for high-temperature service. The pipe shall be suitable for bending, flanging (vanstoning), and similar forming operations, and for fusion welding. Grade P2 and P12 steel pipes shall be made by coarse-grain melting practice. Our products for ASTM A335 alloy steel pipes have been listed as follows:

ASTM A335 P92 ASTM A335 P91 ASTM A335 P9 ASTM A335 P5 ASTM A335 Grade P22 ASTM A335 P11

The steel material shall conform to chemical composition, tensile property, and hardness requirements. Each length of pipe shall be subjected to the hydrostatic test. Also, each pipe shall be examined by a non-destructive examination method in accordance to the required practices.

The range of pipe sizes that may be examined by each method shall be subjected to the limitations in the scope of the respective practices. The different mechanical test requirements for pipes, namely, transverse or longitudinal tension test, flattening test, and hardness or bend test are presented.
