This Standard can also be used to evaluate the ductility of metallic tube. This Standard is applicable to the metallic tube, of which the outer diameter is more than 150 mm, the wall thickness is not more than 40 mm and the inner diameter is more than 100 mm. 2 Principle Cut a section of tube ring sample from one end of the metallic tube; let the metallic tube ring sample bear the circumferential deformation until fracture occurs. 3 Test equipment Use 2 cylindrical pins of the same diameter; their axes are parallel, and relatively movable; remain parallel during the movement. In principle, the diameter of the cylindrical pin shall be the minimum value of the allowable strength. The diameter of the cylindrical pin shall be at least 3 times the wall thickness of the tube ring, if the inner diameter of the metallic tube ring is allowed (as shown in Figure 1). in millimeters ......Source: Above contents are excerpted from the full-copy PDF -- translated/reviewed by: www.ChineseStandard.net / Wayne Zheng et al. |
