Recently, Xinyue has a new cargo now ready for delivery---ASTM A335 Grade P9. This order is seamless steel pipe, with outer diameter 5 inches with SCH 40 wall thickness. This cargo is alloy seamless steel pipe. Thus you can see that Xinyue can provide alloy steel pipe, stainless steel pipe, and carbon steel pipe.

ASTM A335 / A335M is Standard Specification for Seamless Ferritic Alloy-Steel Pipe for High-Temperature Service.

ASTM A335 / A335M covers 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. 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 with 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.
