To present a summary of the guidelines and practices presently being used by the aerospace industry for the selection of coiled tubes, flexible hoses, swivel fittings, and extension fittings in aircraft fluid systems.
This SAE Aerospace Standard (AS) defines a series of standardized tube walls to be used for high pressure hydraulic tubing. These tube walls are applicable to all homogenous tube materials (i.e., aluminum, steel, titanium) throughout a rated pressure range of 1000 to 8000 psi and a maximum rated operating temperature range of 160 to 450 °F. All future aerospace applications for which a required tube outside diameter/tube wall combination is not presently available shall be selected from the table contained herein (see Figure 1).
This SAE Aerospace Recommended Practice (ARP) establishes the method for qualification testing of tube joints and fitting attachments, using the flexure test method described in ARP1185. This qualification test method allows the determination of S-N type stress versus cycles or D-N type deflection versus cycles curves, as illustrated in AIR1418 as an alternate to flexure testing to a minimum endurance stress level.

This AIR is intended to describe and document a process presently in use for proof testing, which at the same time improves the fatigue life of 304 1/8 hard CRES and 3A1-2.5V CWSR titanium hydraulic tubing lines.

This SAE Aerospace Information Report (AIR) presents flexure fatigue strength of tube fitting joints in the form of graphs showing applied deflection D and total calculated axial stress S versus number of cycles to failure N. The graphs have been prepared from data obtained by actual testing conducted in accordance with ARP1185.
