Fittings, Tube, Fluid Systems, Separable, Beam Seal, 3000/4000 psi, General Specification for
This specification covers the design requirements and test procedures for separable beam seal fittings which includes end fittings (see 2.3.4), fitting bodies (see 2.3.7), and boss fittings (see 2.3.2) for use in aerospace fluid systems. Design requirements are for class 3000 in corrosion resistant steel (15-5 PH, 17-4 PH CRES) only and for class 4000 in titanium alloy (Ti) and corrosion and heat-resistant steel (nickel alloy 718 CRES) only. Definition of fittings and related terms are defined in 2.3.
Corrected error to sample numbers in burst test (4.6.3); modified periodic control testing procedures/tests (4.4.3); clarified flexure Tables 2A, 2B, and 2C; and added new tubing material options to Table 1.
