ASTM A192/ASME SA192 Seamless Carbon Steel Boiler Tubes

ASTM A192/ASME SA192: Seamless Carbon Steel Boiler Tubes for High-Pressure Service Standard: ASTM A192/ASME SA192
JST can supply various grades of seamless boiler pipes, such as A192.

Description ASTM A192/ASME SA192 seamless carbon steel boiler tube is applicable to carbon steel boiler and super heater 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. JST 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.

• JST hot-rolled high pressure seamless boiler pipe does not need heat treatment. After the last cold drawing, cold drawn high-pressure seamless carbon steel boiler pipe will enter into the micro oxidation non-oxidation thermal treatment furnace. It will conduct heat treatment in the temperature of 1200℉ (650 ℃) or a higher temperature, so that the surface of seamless carbon steel boiler tube is in non oxidation state and is relatively smooth, and the performance will be more stable.
• JST owns professional hardness testing equipment and professional testing personnel for testing seamless boiler pipes. Brinell hardness should not exceed 137 HB for those pipes with the wall thickness of more than or equal to 0.200 inch (5.1 mm), while it should not exceed 77 HRB for those seamless carbon steel boiler tubes with the wall thickness of less than 0.200 inch (5.1 mm).
• Our company configures multiple inspection machines, such as British UNICORN ultrasonic joint inspection machine, magnetic particle testing machine, eddy current testing machine and also has professional inspectors. Inspection personnel are trained and obtain the appropriate qualifications for testing seamless boiler pipes. According to customers' requirements, JST high-pressure seamless carbon steel boiler tubes can do flaw detections. If requested by customers, we can also provide inspection reports.
• We can provide hot-trimming or cold drawing for customers.
