SAE AMS5588G Page 3 of 6 3.2 Condition Solution heat treated, and unless solution heat treatment is performed in an atmosphere yielding a bright finish, pickled as required. No specific solution heat treating instructions are specified but
16、 it is recommended that the tubing be solution heat treated by heating in a suitable protective atmosphere to 2150 F 25 (1177 C 14), holding at heat for a time commensurate with section thickness, and cooling rapidly. In no case shall the solution heat treatment temperature be lower than 2100 F (114
17、9 C). 3.3 Fabrication Tubing shall be fabricated from hot or cold rolled strip, fusion welded without addition of filler metal, cold drawn, and solution heat treated. The cold drawing operation on tubing 3.0 inches (76 mm) and under in nominal OD shall result in not less than 15% reduction in wall t
18、hickness; the amount of wall thickness reduction on tubing over 3.0 inches (76 mm) in nominal OD shall be as agreed upon by purchaser and vendor. 3.4 Properties Tubing shall conform to the following requirements: 3.4.1 Tensile Properties Shall be as shown in Table 2, determined in accordance with AS
19、TM E 8/E 8M on tubing having nominal OD of 0.125 inch (3.18 mm) and over with nominal wall thickness of 0.015 inch (0.38 mm) and over.

21、formation of cracks or other visible defects, flaring at room temperature by being forced axially with steady pressure over a hardened and polished tapered steel pin having a 74-degree included angle to produce a flare having a permanent expanded OD not less than 1.2 times the original nominal diame
22、ter. 3.4.4 Pressure Test Tubing shall show no bulges, leaks, pinholes, cracks, or other defects when subjected to an internal hydrostatic pressure (P), except that a diametric permanent set of 0.002 inch per inch (0.002 mm/mm) of diameter is acceptable. The hydrostatic pressure (P) shall be determin
23、ed from Equation 1.

24、g to the best practice for high quality aircraft tubing. It shall be smooth and free from grease, oil and other matter, heavy scale or oxide, burrs, seams, tears, grooves, laminations, slivers, pits, and other imperfections detrimental to usage of the tubing. Surface imperfections such as handling m
25、arks, straightening marks, light mandrel and die marks, shallow pits, and scale pattern will not be considered injurious if the imperfections are removable within the tolerances specified for wall thickness, but removal of such imperfections is not required. 3.5.1 If beads are present at the weld on
26、 the inner surface of tubing over 3.0 inches (76 mm) in nominal OD, such weld reinforcement shall be not thicker than 0.010 inch (0.25 mm).
