ASTM A192 Carbon Steel Seamless Tube For Boiler For High-Pressure
ASTM A192 Carbon Steel Tube specification covers Seamless Carbon Steel Boiler Tubes for High-Pressure Service. Recommended pipe size will be developed by us upon receipt of your inquiry. A print or sketch of the part to be produced should be included. Grade, chemical analysis and surface condition are carefully considered, and production processes are tailored to achieve the best tubing for the end use. ASTM A192 Seamless Steel Tube is applied as minimum-wall-thickness, seamless carbon steel boiler and superheater tubes for high-pressure service.
YUHONG supplies ASTM A192 steel tube in hot rolled and cold drawn delivery state, It is generally used for high-pressure boiler (working pressure does not exceed 9.8Mpa and the working temperature between 450 ℃ -650 ℃) heating surface tubes, header, economizer, superheater, reheater.

ASTM A192 is the standard specification covering minimum-wall-thickness seamless carbon steel boiler and superheater tubes for high pressure service. The tubing sizes and thicknesses usually furnished to ASTM A192 are 1/2″ to 7″ [12.7 mm to 177.8 mm] outside diameter and 0.085″ to 1.000″ [2.2 mm 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.
