Description:
ASTM A210(ASME SA210/210M)
Seamless carbon steel pipe for high pressure boiler and superhearter
ASTM A210 is the standard covers seamless middle-carbon steel boiler and superheater tubes. It is minimum-wall-thickness tubes under this standard. Material manufacturing shall be killed. Tubes shall be made by seamless process, marked as either hot-finished or cold-finished.
Applications:
1. Super heater
2. Pressure vessel
3. Boiler, boiler flue, including safe ends, arch and stay tubes
4. Heat supply/heat transfer equipment,
etc.
Competitive Advantage:
Good management, Serious quality control, and always put customer's benefit on first consideration.
Best price with top quality and good service!
