ASME SA249 Tubing
Tubos India is one of the large manufacturers for high quality ASTM A249 / ASME SA249 Tubes. Our ASTM A249 Specification for nominal-wall-thickness welded tubes and heavily cold worked welded tubes made from the austenitic steels with various grades intended for such use as a heat exchanger, boiler, superheater or condenser tubes.
ASME SA249 material shall conform to the prescribed tensile and hardness properties such as yield strength, tensile strength, elongation and Rockwell hardness number. Also, each astm a249 tube undergo mechanical tests such as flattening test, tension test, flange test, reverse-bend test, hardness test, and hydrostatic or nondestructive electric test.
