ARP4146C
This SAE Aerospace Recommended Practice (ARP) addresses the design, installation, and testing of coiled tube assemblies using Ti-3Al-2.5V cold worked, stress relieved (CWSR) tubing per AMS4945. It specifically details five different configurations of coiled tubing. The configurations detailed herein should be compatible with pressure levels up to 8000 psi (55.2 MPa) upon completion of analysis for the actual stress and life requirement of the intended application. Formal qualification tests are recommended to verify satisfactory installation, clamping, and the life of each unique design. NOTE: For information on design of coiled tube assemblies using CRES steel tubing, see ARP584.

CURRENT
ARP4763
This SAE Aerospace Recommended Practice (ARP) is intended as a guide to define the requirements for aerospace hydraulic relief valves, including details pertinent to the design, performance, fabrication, and testing of the relief valves. NOTE 1: This ARP is for hydraulic system full-flow relief valves; ARP4835 has been developed to specifically cover thermal relief valves. NOTE 2: This document does not cover the modification of cracking pressure by external input; either hydraulic, electric, or pneumatic.

CURRENT
ARP4741
This SAE Aerospace Recommended Practice (ARP) establishes the requirements for the design, manufacture, and qualification of four hydraulic switching valves used in airborne applications. Two are pressure operated, Type IA and IB and two are solenoid/pilot operated, Type IIA and IIB. They are applicable to four pressure classes 3000, 4000, 5000 and 8000 psi. The equipment as designed is intended to be installed in hydraulic systems designed to AS5440 for military applications or ARP4752 and ARP4925 depending on the type of aircraft for commercial applications. Additional or refined requirements shall be contained in the detail (procurement) specification and these shall take precedence over any potentially conflicting requirements of this ARP or documents referenced by this ARP.

CURRENT
ARP584D
This SAE Aerospace Recommended Practice (ARP) addresses the design, installation, and testing of coiled tube assemblies ranging from 1/4 inch (6.3 mm) to 1.0 inch (25 mm) diameter using CRES tubing per AMS-T-6845, unless otherwise approved by the Procuring Activity. This ARP specifically details three different configurations of coiled tubing. These configurations should be compatible with pressure levels up to 3000 psi (20.7 MPa) upon the completion of the analysis for the actual stress and life requirement of the intended application. However, formal qualification tests are recommended to verify the satisfactory installation, clamping, and the life of each unique design. NOTE: Refer to ARP4146 for information on design of coiled tube assemblies using Titanium tubing.

RECOMMENDED PRACTICE FOR THE DESIGN OF TUBING INSTALLATIONS FOR AEROSPACE FLUID POWER SYSTEMS

1976-04-01
HISTORICAL
ARP994
This document is a compendium of recommended practices for the design of tubing systems for the transmission of liquid and gasses influid power systems for aerospace vehicles such as aircraft, missiles and boosters, and is considered applicable to the design of future space vehicles and other applications using aircraft technology. Primary emphasis is given to recommended practices for line sizing, tube routing, supports and clamping, stress considerations and permissible defects, and provisions for flexure through the use of flexible hoses, coiled tubes, swivel joints, and expansion glands. Fluid power systems are differentiated from the normal aircraft fuel and oil systems and the various fluid systems used for environmental control and air conditioning systems; however, the practices cited herein will in many cases be applicable to these other systems.
