Anotácia

This specification covers the standard for UNS N08923, UNS N0835, and UNS N08926 welded tube for general corrosion applications. The tubes shall be manufactured from flat-rolled alloy by an automatic welding process with no addition of filler metal. The tubes shall also undergo cold-working subsequent to welding and prior to final heat treatment. Mechanical properties such as tensile strength, yield strength, and elongation shall be examined accordingly. Each specimen shall also be subjected to a flattening test, flange test, and nondestructive testing such as hydrostatic, pneumatic, eddy current, ultrasonic, leak, and electric test.
