This SAE Aerospace Recommended Practice (ARP) covers visible surface defects on aerospace hose assemblies which have been installed and are functioning within a working environment at the time of visual inspection.
This SAE Aerospace Standard establishes the requirements for a V-retainer coupling, flanges, and seal suitable for joining high-pressure and high-temperature ducting in aircraft bleed air systems. The rigid coupling joint assembly, hereafter referred to as “the joint,” shall operate within the temperature range of -65 to +1200 °F.
This Aerospace Recommended Practice (ARP) is intended to establish recommended installation torque value limits and test criteria for machined flared and flareless hose and tube end fitting connections. Assembly of bite-type MS21922 flareless sleeves is not included in this ARP (see MIL-F-18280). This ARP is applicable to two types of connections and two basic material classifications.
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
