Material of tube sheet is Cr18N10T. The tube sheet has cylindrical shape with inner diameter 800mm and the wall thickness 135mm. Cracks may start from inner surface or from the holes of tube sheet. Inspection possibilty is only from inner side of tube sheet.         Reply  Translate  Close   Jim Knowles Jim Knowles 05:48 Jul-10-2002 Re: UT detection of SG tube sheet cracks : I need information about the UT technique for detection axial cracks in the tube sheet of horizontal steam generator of NPP WWER 440 type.
