Fittings, Welded, Hydraulic, Titanium, and Corrosion Resistant Steel and Nickel, 3000 psi Hydraulic
This document defines the requirements for weld fittings and machine weldments using an orbiting welding head suitable for use on cold worked 3Al 2.5V titanium, 21Cr 6Ni 9Mn CRES and 718 nickel alloy tubing. Fitting standards covered by this specification include non-separable welded elbow, tee, and reducer fittings, and reconnectable 24 degree cone fittings such as sleeves and unions.
Rationale: The document has been revised to specify PRI-QPL, to clarify cleaning requirements, to change test references from MIL H-5440 to AS18280, to include periodic control tests, and to make updates.
