ASTM A192 Standard Specification for Seamless Carbon Steel Boiler Tubes for High-Pressure Service

This guide covers standard specifications for minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high-pressure service. The steel shall conform to the required chemical composition for carbon, manganese, phosphorus, sulfur, and silicon. The tubes shall have a hardness number not exceeding a specific value. The following mechanical tests shall be conducted, namely: flattening test; flaring test; hardness test; and hydrostatic test.

1.This specification covers minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high-pressure service.

2.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.

3.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.
