This specification covers fittings intended for general corrosion-resisting and elevated-temperature services, factory made from unalloyed titanium and titanium alloys. The titanium for welding fittings may consist of billets, bars, plates, seamless or welded pipe or tube that conforms to all the requirements for manufacturing process, testing, chemical composition, and mechanical properties. Forging, forming, or shaping operations may be performed by hammering, pressing, piercing, extruding, upsetting, rolling, bending, fusion welding, or by a combination of two or more of these operations. The titanium shall conform to the requirements as to prescribed chemical composition. Product analysis tolerances of aluminum, carbon, chromium, hydrogen, iron, molybdenum, nickel, niobium, nitrogen, oxygen, palladium, ruthenium, silicon, vanadium, zirconium, and some residuals shall be specified. The titanium shall conform to the requirements as to tensile properties prescribed in the specifications.
This abstract is a brief summary of the referenced standard.

1.1 This specification2 covers fittings intended for general corrosion-resisting and elevated-temperature services, factory made from unalloyed titanium and titanium alloys. The term welding fittings applies to butt-welding parts such as 45° and 90° elbows, 180° returns, caps, tees, reducers, lap-joint stub ends, and other types.
1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
