ABSTRACT
This specification covers the requirements for 34 grades of titanium and titanium alloy seamless pipe intended for general corrosion resisting and elevated temperature service. Alloys may be supplied in the following conditions: Grades 5, 23, 24, 25, 29, 35, or 36 annealed or aged; Grades 9, 18, 28, or 38 cold-worked and stress-relieved or annealed; Grades 9, 18, 23, 28, or 29 transformed-beta condition; and Grades 19, 20, or 21 solution-treated or solution-treated and aged. The grades shall conform to the required chemical composition for nitrogen, carbon, hydrogen, iron, oxygen, aluminum, vanadium, tin, ruthenium, palladium, chromium, nickel, niobium, zirconium, silicon, and titanium. Chemical analysis and product analysis shall be performed. Mechanical requirements shall conform to the required room temperature values for tensile strength, yield strength, and elongation. The following shall also be performed: tension, flattening, bend, and hydrostatic tests.
