Standard Specification for Seamless and Welded Unalloyed Titanium and Titanium Alloy Welding Fittings

SCOPE
1.1 This specification 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.
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.
