One such method is pipe straightening. Welding pipe can cause the pipe to deform in strange ways because of the curved surfaces on which the stresses act during the heating and cooling process. Many fabricators will fill the pipe with fine-grained dry sand and close the ends of the pipe. The pipe is then heated and straightened.Acceptable Design for Unequal Wall ThicknessInternally, either a straight bore followed by a 30° slope or a taper bore at a maximum slope of 1 to 4 for a minimum distance of 2 times the pipe minimum wall are required. The surface of the weld can also be tapered to accommodate differing thickness. This taper should not exceed 30°.
