What is ASTM A192?

ASTM A192 is a standard for seamless carbon steel boiler and superheater tubes with minimum wall thickness for high-pressure applications. The standard is issued under the fixed designation A 192/A 192M. It is under the jurisdiction of ASTM Committee A01 on Steel.

ASTM A192 is generally used for high-pressure boilers with a working pressure that does not exceed 9.8Mpa. The tubes are available in hot rolled and cold drawn delivery states.

ASTM A192 Seamless Steel Tube

ASTM A192 Seamless Steel Tube is applied as minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high-pressure service.

Scope

1.1 This specification2 covers minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high-pressure service.

1.2 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.

1.3 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.

1.4 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 values 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.

1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
