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 Standard (AS) establishes the requirements for 24° cone flareless fluid connection fittings and nuts and bite type flareless sleeves (see Section 6) for use in aircraft fluid systems at an operating pressure of 5000 psi for the fittings and nuts and 3000 psi for the bite type sleeves.
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.
These formulae shall be used to determine drop dimensions for simple bend tube fittings utilizing flare and flareless end connection designs from 0° to 90° used in aircraft and aerospace applications. Individual design standards shall specify parameters, such as centerline bend radius (R), straight tangent length to accommodate bending equipment (X1 and X2), and nut to be used.
