ASTM B626 specification covers welded tubes made from UNS N10276, UNS N06022. It is used in petrochemical process equipment and gas turbines.

ASTM B626 - Tubes

ASTM B626 Tube

ASTM B626 Welded Tube are intended for heat exchanger and condenser tube general corrosive service for heat resisting applications. The Hastelloy welded tube is long with narrow diameter giving excellent resistance to corrosive atmosphere. The tube has different end used in different application with different diameter sizes. The tubes shall be made from flat-rolled alloy by an automatic welding process with no addition of filler metal, and shall be furnished in the solution annealed and descaled conditions.

Scope And Manufacturing

ASTM B626 specification covers welded tube made from high temperature alloys with UNS N10276, UNS N06022). This specification covers tube 1/8 to 31/2 in. (3.2 to 88.9 mm) in outside diameter and 0.015 to 0.148 in. (0.41 to 3.7 mm) inclusive, in wall thickness. Materials shall adhere to mechanical (tensile strength, yield strength, and elongation), chemical composition, flattening test, flange test, hydrostatic test, pneumatic test, and eddy current test requirements. These material is processed through different test to determine its quality.

ASTM B626 Hastelloy Welded Tubes is a wrought nickel base alloy with excellent high temperature strength and oxidation resistance. Siddhagiri Metals and Tubes offers Hastelloy C276, Hastelloy C22 Welded Tube on large scale.


ASTM B626 specification covers welded Hastelloy C276 and Hastelloy C22 Tubes. It is recommended, especially for use in furnace applications because it has unusual resistance to oxidizing, reducing, and neutral atmospheres.
