6、erties 4.2.1 Torsional Yield Strength (0.1 % Offset) 262-331 MPa (38 000-48 O00 psi) TITLE: REVISION: Steel Tubing, Power Transmission F-1 The torsional yield strength shall be determined using the following relationship: TxD = 0.196 (D4 - d4) S = Torsional Yield Strength (psi) T = Yield Torque (in-
7、lbf) D = Outside Diameter (in) d = Inside Diameter (in) 4.2.2 Yield torque shall be determined at 0.1% offset. Using a gage length of 61.0 cm (24 in), a 0.1% offset is equal to an angular displacement of 1.375“ in the plot of torque (in-lbf) versus angular displacement (degrees). 4.2.3 Hardness Rock
8、well B 80-95. 4.2.4 Flaring Test Tube shall withstand a minimum expansion of the I.D. on one end to 111% (flash-in) and 105 percent (mandrel drawn) of original dimension without splitting or cracking in the weld. The flaring test shall be performed on a conical mandrel with an included angle of 60“
9、as described in ASTM A-370, Supplement II. The test sample shall be a section 10.2 cm (4 in) long which has been cut from the tube. Ends of the sample shall be perpendicular to the tube axis, burrs shall be removed, and a sharp corner maintained. 4.2.4.1 Optional Method A test mandrel shown in Figur
10、e 1 may be substituted for the 60“ mandrel. Tubing shall not split when the I.D. is expanded to the required diameter for a minimum distance of 2.5 cm (1.0 in). 4.2.5 Dimensional Tolerances: See Table 1, page 5. 4.2.5.1 Flash Height Flash shall be limited for a distance of 31.8 mm (1.25 in) from the
11、 ends of the tube to a maximum height of O. 10 mm (0.004 in) and controlled throughout the remaining length to the following limits: Wall Thickness BWG Flash Height - Maximum mm - 1.65-3.05 in 0.065-0.120 16-11 mm 0.79 - in 0.03 1 3.40 and Over 0.134 and Over 10 and Under 1.57 0.062 NOTE: This speci
12、al flash limitation at each end of the tube refers to tubing cut to a particular length (prior to assembly) and does not apply to bulk tubing as purchased.
