39、 Comp. 321 (AMS5689) 3.3 Design and Construction The hose assembly shall consist of a seamless PTFE inner tube, corrosion-resistant steel-wire reinforcement, and corrosion-resistant steel or nickel alloy end fittings as required to meet the construction and performance requirements of this specifica
40、tion and as required for its intended use. 3.3.1 Inner Tube The inner tube shall be of a seamless construction of virgin PTFE resin of uniform gage. It shall have a smooth bore and shall be free from pitting or projections on the inner surface. Additives may be included in the compound from which th
41、e tube is extruded. 3.3.2 Reinforcement The reinforcement shall consist of corrosion-resistant steel wires conforming to the applicable specifications listed in 3.2.1. The wires shall be so arranged over the inner tube as to provide sufficient strength to ensure conformance with the requirements spe
42、cified herein. Broken reinforcing wires shall be cause for rejection. Crossed-over reinforcing wires shall not be cause for rejection of the hose assembly. 3.3.3 Fittings All fittings shall be permanently attached and proven to meet the requirements herein. Standard hose assemblies shall have flared
43、 fittings to mate with AS4395; flareless fittings according to NAS1760 to mate with AS33514 or AS4375; or beam seal fittings per AS85421. Fitting hex portions shall fit standard wrench openings. 3.3.3.1 Straight Fittings Straight fittings shall be of one piece construction. Weld or braze joints must
44、 not be located in the fluid paths, except welded and redrawn corrosion-resistant steel tubing in accordance with 3.2.1 may be used. 3.3.3.2 Other Fittings Other fittings, including elbow fittings, shall be of one piece construction to the maximum extent possible. However, those made with other than
45、 one piece construction can use welded and redrawn corrosion-resistant steel tubing in accordance with 3.2.1 and shall employ a butt weld joint method. 3.3.3.3 End Fitting Collars (Sockets) All end fitting collars (sockets) crimped or swaged, fabricated from Type 304 stainless steel are required to
46、be capable of passing an embrittlement test as specified in ASTM A262 Practice E, prior to assembly to the nipple or swaging operation. Sockets fabricated from stabilized austenitic steel (304L, 321, or 347) are acceptable without being subjected to the embrittlement test. 3.3.3.4 Fitting Finish 3.3
47、.3.4.1 Corrosion Resistant Steel Parts Unless otherwise specified, corrosion resistant steel parts shall be passivated in accordance with AMS2700.
