ASTM A213 Standard Specification for Seamless Boiler Tubing

ASTM A213/ASME SA213 covers low alloy steel pipes and minimum-wall-thickness, seamless ferritic and austenitic steel, boiler, and super-heater tubes, and austenitic steel heat exchanger tubes. ASTM A213 specification offers manufacture and purchasing requirements for manufacturers and users, The main information contains grade, size, finishes, test, and other terms. Designated Grades TP304,TP304H,TP304L,TP310S, TP310HCbN, TP316, TP316H, TP316L etc. The equivalent standard is ASME SA213.

ASTM A213 Tubing Standard Sizes
ASTM A213 tubing sizes and thicknesses usually furnished to this specification are 1/8 in. [3.2 mm] in inside diameter to 5 in. [127 mm] in outside diameter and 0.015 to 0.500 in. [0.4 to 12.7 mm], inclusive, in minimum wall thickness or, if specified in the order, average wall thickness.

ASTM A213 Seamless Tube Fabrications
We are a professional ASTM A213 seamless tube supplier, the manufacturing process starts from the extrusion of the billet, by hot rolling, cold rolling, and cold drawn methods to control size and tolerance, heat treatment will be finished after cold working to achieve steel properties.
