What is ASTM A249 ASME SA249?

ASTM A249 is specifies standard specification for nomina wall thickness welded tubes and heavily cold worked welded tubes made from the austenitic steel with various grades intended for such use as a boiler, superheater, scambiatore di calore, or tubi del condensatore. Heat and product analysis shall conform to the requirements as to chemical composition for carbon, manganese, phosphorous, sulfur, silicon, chromium, nickel, molybdenum, nitrogen, copper, and others. All materials shall be furnished in the heat-treated condition in accordance with the required solution temperature and spegnimento method.

ASTM A249 Tubing Test Items

When the final trattamento termico is in a continuous furnace, the number of tubes of the same size and from the same calore in a lot shall be determined from the prescribed size of the tubes. The material shall conform to the prescribed tensile and durezza properties such as resistenza alla trazione, yield strength, elongation, and Durezza Rockwell number. The steel shall undergo mechanical tests such as tension test, flattening test, flange test, reverse-bend test, hardness test, and hydrostatic or nondestructive electric test. The grain size of different grades of steel shall be determined in accordance with the test methods.

Chemical Analysis, 100 % PMI.
Proprietà meccaniche (resistenza alla trazione finale, resistenza allo snervamento, allungamento),
Proprietà tecniche (test di appiattimento, test di flessione, test di soffiatura, test di impatto), ispezione delle dimensioni esterne, test idrostatico, test a raggi X.

ASTM A249 ASME SA249 Tubes Size

The tubing sizes and thicknesses usually furnished to this specification are 1/8 in. [3.2 mm] in inside diameter to 12 in. [304.8 mm] in outside diameter and 0.015 to 0.320 in. [0.4 to 8.1 mm], inclusive, in wall thickness. Tubing having other dimensions may be furnished, provided such tubes comply with all other requirements of this specification.
