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.
Size range from OD: 12.7 – 127mm (1/2 – 5 in.) WT: 0.9 – 12.7mm (0.035 – 0.5in.), or as per customer’s requirement
Applications:
Mianly used for boiler, boiler flue, including safe ends, arch and stay tubes. Superheater. Heat-exchanger and other heat supply/heat transfer equipment, etc.
Competitive Advantage:
Good management, best price with top quality and good service! Always put customer's benefit on first consideration.
