A210 seamless steel pipe is an important standard for seamless carbon steel and alloy steel pipes used in boilers and super heat exchangers.

ASTM A213 covers seamless ferritic and austenitic steel boiler, Boiler Tube, and heat-exchange tubes, designated Grades T5, TP304, etc. Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H.

ASTM A106 seamless steel pipe includes two processes: cold drawn and hot rolled. Among them, cold drawn has higher dimensional accuracy than hot rolled, and the surface of hot rolled steel pipe is relatively rough. The large-diameter seamless steel pipe is hot-rolled steel pipe, and the small-diameter is cold drawn.

S235JRH grade belongs to standard EN10219. EN10219 S235JRH welded steel pipe is a carbon structural steel, JR means its impact properties are at room temperature.
