Quick Inquiry. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification. Stainless welded heat exchanger tubes, Stainless welded Condenser tubes, Stainless welded Boiler tubes, austenitic stainless-steel tubes, stainless boiler tubes, stainless condenser tubes, stainless heat exchanger tubes, stainless steel tube, stainless superheater tubes, temperature service applications, welded steel tube and heavily cold worked HCW tubes.

One flattening test shall be made on specimens from each end of one finished tube, not the one used for the flaring test, from each lot. One flange test shall be made on specimens from each end of one finished tube, not the one used for the flattening test, from each lot.

Each tube shall be subjected to either the hydrostatic or the nondestructive electric test. The purchaser may specify which test is to be used. If you are interested in our products or cooperation with us, even having a comment or a suggestion, please contact us now for more detailed information.

ASTM A249 Tubing

ASTM standards organization develops and approvals technical standards, to improve materials, products, systems, and services requirements. ASTM A welded tubes are for boiler, super heater, heat exchanger, condenser system, the pressure equipment is used to transfer heat. ASTM A tubing is for general service, usually, it is applied in equipment and instruments, also under low or high temperature environment, therefore, ASTM A tubing is also used for heat transfer equipment. However, in some cases, Ferritic and Duplex steel tubes are produced to comply with A or A standard, Ferritic steel tubes can reduce cost, and duplex steel tubes increase strength and longevity. ASTM A indicate welded tubes, the tubes should be cold worked or cold drawn method, prior to final heat treatment. ASTM A tubes should be welded type or seamless type, which is made in cold finished or hot finished. Each tube should be conducted to the nondestructive test or the hydrostatic test, in many cases, nondestructive test refer to eddy current test or air underwater test.
