Product Introduction

ASTM A192 / A192M is the standard applicable to seamless carbon steel boiler tubes for high-pressure service

ASTM A192 seamless steel tube 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.

ASTM A192 seamless steel tubes 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.

For lengths greater than 24 ft [7.3 m], the above over-tolerances shall be increased by 1⁄8 in. [3 mm] for each 10 ft [3 m] or fraction thereof over 24 ft or 1⁄2 in. [13 mm], whichever is the lesser.  
 
 

ASTM A192 Seamless tubes Hydrostatic Test Pressures

Each tube shall be subjected to the hydrostatic pressure test, or instead of this test, a nondestructive test may be used when specified by the purchaser.

Hydrostatic Test Pressures

2 to 3 [50.8 to 76.2], excl 2500 [17]

ASTM A192 Seamless Tubes Flattening Test

One flattening test shall be made on specimens from each end of two tubes selected from each lot or fraction thereof.

ASTM A192 Seamless Tubes Flaring Test

One flaring test shall be made on specie- men from each end of two tubes selected from each lot or fraction thereof. These tubes shall be selected apart from those used for the flattening test.
