ASTM A 192/A 192 M
Standard Specification for
Seamless Carbon Steel Boiler Tubes for High-Pressure Service
Scope: This specification covers minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high pressure service. The tubing sizes and thicknesses usually furnished to this specification are 1/2 in. to 7 in. [12.7 to 177.8 mm] outside diameter and 0.085 to 1.000 in. [2.2 to 25.4 mm], inclusive, in minimum wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
Mechanical property requirements do not apply to tubing smaller than 1/8 in. [3.2 mm] inside diameter or 0.015 in. [0.4 mm] thickness. When these products are to be used in applications conforming to ISO Recommendations for Boiler Construction, the requirements of Specification A520 shall supplement and supersede the requirements of this specification.
Application: It is used for high pressure minimum-wall thickness seamless carbon steel Boiler and Superheater tube.
Main Steel Tube Grade: A192 etc. Other grade can also be provided after consulting with customers.
