ASTM A192 cold drawing seamless boiler tube for high-pressure settings
ASTM A192/ASME SA192 seamless carbon steel boiler tube is applicable to carbon steel boiler and superheater with high pressure and the minimum thickness. It is typically used for manufacturing high-pressure boiler (The working pressure is not more than 9.8 MPa and the working temperature is between 450℃ and 650℃.), heating surface tube box, economizer, superheater, reheater, boiler water wall and steam pipe. Bestar seamless boiler pipes are featured with high yield strength, high tensile strength and high elongation. The pressure resistance is guaranteed by the very smooth inside surface.
