Reverse Bend Test The sample shall then be opened and bent around a mandrel with a maximum thickness of four times the wall thickness, with the mandrel parallel to the weld and against the original outside surface of the tube. The weld shall be at the point of maximum bend.

There shall be no evidence of cracks or of overlaps resulting from the reduction in thickness of the weld area by cold working. When the geometry or size of the tubing make it difficult to test the sample as a single piece, the sample may be sectioned into smaller pieces provided a minimum of 4 in.

Practices E and E contain additional information regarding the capabilities and limitations of eddy-current examination. The provisions of this speci? It should be recognized that different techniques should be employed to detect differently oriented imperfections.

This test has the capability of? This test may not detect very tight, through-the-wall defects or defects that extend an appreciable distance into the wall without complete penetration. This requirement does not preclude additional testing at earlier stages in the processing. The methods used for cleaning and preparing the surfaces for examination shall not be detrimental to the base metal or the surface? Other nondestructive tests may be applied to the end areas, subject to agreement between the purchaser and the manufacturer.

The holes shall be drilled radially and completely through the tube wall, with care being taken to avoid distortion of the tube while drilling. The holes shall not be larger than 0.

For welded tubing, if the weld is visible, one of the multiple holes or the single hole shall be drilled in the weld. Said notch shall have a depth not exceeding The length of the notch shall be compatible with the testing method. The depth of the notches shall not exceed The width of the notch shall not exceed two times the depth. For welded tubing, the notches shall be placed in the weld, if the weld is visible.

Notch depth shall not exceed Notch length shall not exceed 1 in.
