ASTM A210——specification for seamless medium-carbon steel boiler and superheater tubes

Date:2021-10-21View:83Tags:ASTM A210 seamless steel tube

ASTMA210/ASME SA210 seamless steel tube for boiler and superheater is a form of seamless medium-carbon steel pipe with minimum wall wider.

 

It can be used as seamless boiler tube, boiler flue pipe (including safe end, vault and support tube) and superheater water pipe. This carbon steel seamless pipe is extensively employed boiler, chemical engineering, electric power some other industries. It may be used ultimately manufacturing of boiler water wall, economizer, reheater and steam pipes.

 

Scope

1.1 This specification covers minimum-wall-thickness, seamless medium-carbon steel, boiler tubes and boiler flues, including safe ends, arch and stay tubes, and superheater tubes. This type is not suitable for safe ending by forge welding.

 

1.2 The tubing sizes and thicknesses usually furnished to this specification are 1/2 in. to 5 in. [12.7 to 127 mm] in outside diameter and 0.035 to 0.500 in. [0.9 to 12.7 mm], inclusive, in minimum wall thickness. Tubing having other with all other requirements of this specification.

 

1.3 Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] in inside diameter or 0.015 in. [0.4 mm] in thickness.

 

1.4 When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction, the requirements of Specification A 520 , shall supplement and supersede the requirements of this specification.

 

1.5 The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the

SI units are shown in brackets. The values stated in each system are not exact equivalents; therefore, each system must be used independently of the other. Combining value from the two systems may result in nonconformance with the specification. The inch-pound units shall apply unless the “m” designation of this specification is specified in the order.
