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.
This recommended practice covers the requirements and qualification tests for two types of flexible all-metal hose assemblies intended for hydraulic use on missile and rocket applications at rated pressures of 4000 psi. Type I -65° to +650 °F service temperature range Type II -65° to +1000 °F service temperature range
This Aerospace Recommended Practice (ARP) establishes uniform requirements and procedures to determine the torsional strength of permanent hydraulic tube joints. It also establishes testing equipment and apparatus for torsion testing.
