Seamless steel pipes can be divided into 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 and other types according to their standards. ASTM American standard seamless steel pipes are in It is relatively common internationally and has many types and branches.
Now the relevant parameters of ASTM seamless steel pipe ASTM stm a210/a210m/astm sa210/sa-210s American standard seamless steel pipe are listed as follows: ASTM A210/A210M/ASME SA-210/SA-210M Purpose: suitable for boiler tubes and boilers Flue pipes, including safety ends, vaults and support pipes, and minimum wall thickness seamless medium carbon steel pipes for superheater pipes. Mainly produces steel pipe grades: A-1, C, etc. After negotiation, other grades of steel pipes can also be supplied.
Seamless steel pipe manufacturing process:
Seamless steel pipes are divided into hot-rolled seamless steel pipes, cold-drawn seamless steel pipes, etc. according to their manufacturing process. The diameter of seamless steel pipes is generally 406mm-1800mm, and the wall thickness is 20mm-220mm. According to their uses, they can be divided into seamless steel pipes for structures, seamless steel pipes for fluids, seamless steel pipes for boilers, and seamless steel pipes for oil pipelines.
