ASTM A213 / ASME SA213 T5 SMLS Tubes
We are the professional manufacturer of ASTM A213 / ASME SA213 T5 SMLS Tubes in China
As a reliable manufacturer and exporter of ASME SA213 T5 Seamless Alloy Steel Tubes, We are supplying high-quality boiler, heat exchanger, and superheater tubes for high-temperature and high-pressure applications.
Grade T5 is a 5Cr-0.5Mo alloy steel offering excellent creep strength, oxidation resistance, and thermal stability, making it ideal for use in power plants, refineries, and petrochemical industries.
ASTM A213 is the Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
This specification covers seamless ferritic and austenitic steel boiler, superheater, and heat-exchanger tubes, designated Grades T5, TP304, etc.
These steels are listed in Tables 1 and 2. 1.2 Grades containing the letter, H, in their designation, have requirements different from those of similar grades not containing the letter, H. These different requirements provide higher creep-rupture strength than normally achievable in similar grades without these different requirements.
The 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. Tubing having other diameters may be furnished, provided such tubes comply with all other requirements of this specification.
