Seamless Boiler Tube ASTM A192 4" XXS 9-12M
ASTM A192 Boiler Tube Specification:
ASTM A192/ASME SA192: Seamless Carbon Steel Boiler Tubes for High-Pressure ServiceStandard: ASTM A192/ASME SA192
ASTM A192/ASME SA192 seamless carbon steel boiler tube implements to carbon steel boiler and super heater substantial pressure and the minimum thickness. It is typically used for manufacturing ruthless boiler (The working pressure is not more than 9.8 MPa and the significant temperature is between 450℃ and 650℃.), heating surface tube box, economizer, superheater, reheater, boiler water wall and steam pipe. The seamless boiler pipes are featured with high yield strength, high tensile strength and high elongation. Pressure to succeed resistance is guaranteed in the very smooth inside material.
The hot-rolled high pressure seamless boiler pipe does not need heat treatment. The cold drawn high-pressure seamless carbon steel boiler pipe will enter into the micro oxidation non-oxidation thermal treatment air conditioner. It will conduct heat treatment in the temperature of 1200℉ (650 ℃) or a more significant temperature.
We have multiple inspection machines including ultrasonic joint inspection machine, magnetic particle testing machine, eddy current testing machine. The inspection personnel are trained and uncover the appropriate qualifications for testing seamless boiler pipes.
