ASTM A192/ASME SA192 Seamless Carbon Steel Boiler Tubes

ASTM A192/ASME SA192: Seamless Carbon Steel Boiler Tubes for High-Pressure ServiceStandard: 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 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. JST 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.

    Advantages of JST Seamless carbon steel boiler tube

    JST hot-rolled high pressure seamless boiler pipe does not need heat treatment. Very first last cold drawing, 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, so how the surface of seamless carbon steel boiler tube is in non oxidation state and is relatively smooth, and the performance will are 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 during or equal to 0.200 inch (5.1 mm), while it will not exceed 77 HRB for those seamless carbon steel boiler tubes with the wall thickness of less than 0.200 inch (5.1 mm).
    Iwowwee configures multiple inspection machines, such as British UNICORN ultrasonic joint inspection machine, magnetic particle testing machine, eddy current testing machine furthermore has professional personnel. Inspection personnel are trained and uncover the appropriate qualifications for testing seamless boiler pipes. As stated by customers' requirements, JST high-pressure seamless carbon steel boiler tubes can do flaw detections. If requested by customers, home furniture also provide inspection reports.
    Can easily provide hot-trimming or cold drawing can be.
