Unless otherwise specified (see 6.2.1),continuous identificationmarking shall be applied in accordance with FED-STD-185.Material may be marked for identificationby means of a vibratory tool, electr
34、o-chemical etching, or paint or ink stenciling in accordance with MIL-STD-792.Markings resulting from those methods shall not reduce the wall thickness belowthe specified minimum. Marking paints or inks shall not contain mercury.Electric arc or impressionmarking is prohibited. Tube with minimum wall
35、 thick-ness less than 0.125 inch shall not be marked by vibratory tool.3.10 Removal and repair of defects. Removal of surface defects shall beaccomplished by grinding, machining or filing with a clean file, provided thewall thickness is not reduced below the minimum specified in 3.4 and the groundar
36、eas are well-faired into the rest of the tube or pipe. A well-faired areashall be considered one in which the bottom radius of the ground area equals atleast 3 times the depth of the defect. If grinding is used to remove thesurface defect, the grinding medium shall be 120 or finer iron-freealuminagr

After such conditioningoperations, the conditioned areas shall bereinspected by the nondestructive inspection techniques used in originallydetecting the defect. Tube shall not be repaired by welding or brazing.3.11 Work
38、manship. Tubes shall be commercially clean, free of films orscale, dirt, chips or any foreign matter. In addition, tubes shall be uniformin quality, sound and free from seams, cracks, laps, burrs, blisters, slivers,scale or other injurious defects such as pitting as determined by visualexamination.
39、Surface imperfectionssuch as handling marks, straighteningmarks, light mandrel, die or roll marks that do not reduce the wall thicknessbelow the minimum specified are permissible,provided the imperfectionshavevisible bottoms and the depth does not exceed 3 percent of the wall thickness.8Provided by
