Title
Fittings, Tube, Fluid Systems, Separable, High Pressure Dynamic Beam Seal, 5000/8000 psi, General Specification For
Scope
This specification covers the design requirements and test procedures for separable beam seal fittings which include end fittings (see 2.4.2), connectors (see 2.4.3), and boss fittings for use in aerospace fluid systems. Design requirements are for Class 5000 and 8000 in titanium, and corrosion resistant steel (CRES). Definition of fittings and related terms are defined in 2.4.
Rationale
This specification is revised to incorporate allowances for shape fittings (Elbows, Tees and Crosses) to be manufactured from either: a) bar-stock per dimensions specified in AS1376 or b) near-net forgings or c) oversize forgings per dimensions specified in AS1376. It is also being revised to replace the lot-to-lot destructive testing with periodic testing.
