Standardization, Hydraulic Tube Walls

1997-03-01
CURRENT
AS4467
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).

CURRENT
AS4700
This SAE Aerospace Standard (AS) establishes the standard installation procedures and torque values for the AS short flareless hydraulic tube fittings in sizes -20 and -24, and parts listed in this standard, made from 6A1-4V Titanium, 15-5 PH CRES, and 7075 Aluminum Alloy.

FLEXURE TESTING OF HYDRAULIC TUBING JOINTS AND FITTINGS

1973-12-01
HISTORICAL
ARP1185
This recommended practice establishes flexure test procedures to determine and classify the fatigue strengths of reconnectable or permanent hydraulic tube joints. The procedure is intended for conducting flexure tests of fittings and joints for hydraulic tubing materials such as AM 350, 21Cr-6Ni-9Mn steel, or 3Al-2.5V titanium. A mean stress is applied by holding system pressure in the specimens and flexing in a rotary or planar bending test machine.

HISTORICAL
ARP1185A
This Aerospace Recommended Practice establishes flexure test procedures to determine and classify the fatigue strengths of reconnectable or permanent hydraulic tube joints. The procedure is intended for conducting flexure tests of fittings and joints for hydraulic tubing materials such as AM 350, AMS 5561 (21Cr-6Ni-9Mn) steel, or AMS 4944 (3Al-2.5V) titanium. A mean stress is applied by holding system pressure in the specimens and flexing in a rotary or planar bending test machine. Flexure testing of metric tubing joints and fittings is covered by MA 2003.
