-
ASTM A213, ASME SA213 American standard (seamless ferritic and austenitic alloy steel pipes for boilers, superheaters, and heat exchangers)
Seamless steel pipes can be divided into various types according to their standards, such as ASTM American standard seamless steel pipes, DIN German standard seamless steel pipes, JIS Japanese standard seamless steel pipes, GB national seamless steel pipes, API seamless steel pipes, etc. ASTM American standard seamless steel pipes are more commonly used internationally, and their types are diverse. The relevant parameters of ASTM A213/A213M/ASME SA213/SA-213M American standard seamless steel pipes are now displayed as follows
Standard:
ASTM A213/A213M/ASME SA213/SA-213M
Usage:
Seamless ferrite and austenitic steel pipes with minimum wall thickness suitable for boilers and superheaters, as well as austenitic steel pipes for heat exchangers.
Main steel pipe grades produced:T11, T12, T22, etc
After negotiation, other grades of steel pipes can also be supplied.

Remarks：
HR：hot rolled CW：cold worked SR：stress relieved A：annealed N：normalized HF：hot rolling Seamless steel pipe manufacturing process. According to its manufacturing process, seamless steel pipes can be divided into hot-rolled seamless steel pipes, cold drawn seamless steel pipes, punching and drawing seamless steel pipes, vertical extrusion seamless steel pipes. The first two processes are to produce general diameter seamless steel pipes, with a diameter generally between 8mm and 406mm and a wall thickness generally between 2mm and 30mm; The latter two are the production of large-diameter thick walled seamless steel pipes. The diameter of seamless steel pipes is generally between 406mm and 1800mm, and the wall thickness is between 20mm and 220mm. According to its purpose, it can be divided into seamless steel pipes for structural use, seamless steel pipes for fluid use, seamless steel pipes for boilers, seamless steel pipes for petroleum pipelines.
