ASTM A213/ASME SA213 Seamless Tube

ASTM A213/ASME SA213: Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater and Heat-Exchanger TubesStandard: ASTM A213/ASME SA213
JST can supply various grades of seamless steel pipes, such as A213T11, A213T12 and A213T22.

Description: ASTM A213 or ASME SA213 seamless tube is applicable to seamless ferritic and austenitic pipes with the minimum thickness in boiler and superheater. It is typically used as heating surface pipe, boiler header (collection box) and steam pipe in low and medium pressure boilers (The working pressure is not additional than 9.8 MPa and the running temperature is between 450℃ and 650℃.), economizer, superheater, reheater, etc. This seamless steel pipe is widely applied in heat exchanger, condenser and heat transfer equipment.

Advantages of ASTM A213/ASME SA213 Seamless Tube

  • Size Control

The medial side diameter of JST seamless steel pipes for boiler, superheater or heat exchanger is 1/8in (3.2 mm), outside diameter 5in (127 mm) and the minimum wall thickness originates from 0.015 to two.500in. (0.4 mm to 12.7 mm). ASTM A213/ASME SA213 also sets the allowable dimension deviation for boiler, superheater and heat exchanger seamless line. JST advanced rolling process can effectively reduce the deviation range and make the size of seamless steel pipe better. We are also able to various pipes spend money on companies customers' requirements and make sure that they stick to ASTM A213/ASME SA213 steel standards.

  • Hydraulic Pressure Test

JST possesses three advanced hydrostatic equipment to sample the density of seamless tubes. Regular find out whether seamless steel pipe leaks out from the inside wall to the skin wall by naked eyes or through pressure drop. The utmost test pressure is up to 120 Mpa, which meet the water pressure test requirements for boiler, superheater and heat exchanger seamless tubes.

  • Inspection

Behavior do nondestructive inspections for seamless steel pipes solution . customers' . JST configures advanced inspection machines that provide magnetic flux leakage inspection, magnetic particle testing, eddy current testing, ultrasonic testing, and so on. We remove test failed seamless tubes promptly for making sure to provide customers with boiler, superheater and heat exchanger seamless steel pipes with stable performance and high quality.

  • Manufacture

In agreement with the requirements of customers, our company can supply pipes for boiler, superheater and heat exchanger adopting hot-trimming and cold finishing.
