I am not familiar with an industry specification or standard that requires NDT after HT on tubulars. Some specific customers or fabricators may do so, but I have not seen a standard that does. I am sure that the material and part design will bear on whether or not it matters - in some cases post-HT NDT is not feasible when rework or removal of defects would result in scrapped tubes.
