ASTM A213 Wall Thickness Tolerances
ASTM A213 specifies Minimum wall thickness, namely, there is no mill under tolerance, only overtolerance, unless specified as average wall thickness is required, permissible variations from the specified average wall thickness shall be +/-10 % of the specified average wall thickness for cold-formed tubes.
Seamless tubing furnished to this specification shall conform to the requirements of Specification ASTM A1016/A1016M, including any supplementary requirements.
Seamless Tube Manufacturing Processes
- The tubes shall be made by the seamless process and shall be either hot finished or cold-finished, as specified.
- Heat treatment shall be done separately and in addition to heating for hot forming.
- The ferritic alloy and ferritic stainless steels shall be reheated. austenitic stainless steel tubes shall be furnished in the heat-treated condition.
- Tubes may be individually quenched in water or rapidly cooled by other means.
- Tubes shall be pickled free of scale. When bright annealing is used, pickling is not necessary.
- Complete tests should be conducted conforming to ASTM A213 or ASTM A1016.
ASTM A213 Testing Requirement
Each tube shall be subjected to the nondestructive electric test or hydrostatic test, Manufacturer Material Test Certification as per EN 10204 3.1 should be provided.
- Tensile property, Elongation
- Hardness testing, Brinell, Rockwell, Vickers hardness
- Flattening testing
- Flaring testing
- Hydrostatic or Nondestructive test
- Intergranular Corrosion Test – ASTM A262/E (option)
ASTM A213 Seamless Tube Manufacturer
We are a professional ASTM A213 seamless tube manufacturer & supplier, having the capability to produce a wide range size seamless tubes for heat exchanger systems, the manufacturing process starts from the extrusion of the billet, by cold rolling and cold drawn methods to control size and tolerance, heat treatment will be finished after cold working to achieve original steel properties, which improve high-temperature resistance and corrosion resistance, then tubes should be under pickling passivation condition.

- ASTM A213 TP321 stainless steel tube
- ASTM A213 duplex stainless steel tube
- ASTM A213 904L stainless steel tube
- ASTM A213 alloy steel tube
ASTM A213 VS ASTM A269
- ASTM A213 pertains to seamless tubes, ASTM A269 can be both seamless and welded tubing.
- ASTM A213 material contains Ferritic and Austenitic Alloy Steel, ASTM A269 only has Austenitic Stainless Steel.
- Dimensional tolerances on outside diameter and wall thickness are not the same.
- ASTM A213 is used in the heat exchanger system, ASTM A269 is for general service use, commonly instrumentation tubing.
- ASTM A213 has ASME version SA213 as an alternative, however, there is no ASME SA269.
- In practice, ASTM A213 and ASTM A269 can be dual-certified standards.
