ASTM A192M Heavy Wall High-pressure seamless steel boiler tubes
This specification covers minimum-wall thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus. Tubes shall be made by the seamless process and shall be cold drawn. Heat and product analysis shall be performed wherein steel materials shall conform to required chemical compositions of carbon, manganese, phosphorus, and sulfur. The steel materials shall also undergo hardness test, flattening test, flaring test, flange test, and hydrostatic test.
The ASTM A 192M / ASME SA-192M belongs to the carbon seamless tubes, which is specially designed for high, middle, low-pressure purpose in seamless carbon steel boilers and as superheater tubes.
