For fixed-tube-sheet heat exchangers, which are classified as Category 1 vessels, is surface inspection required for the weld joints between the shell and the tube sheet? Or in what situation is it necessary to do it?

Detailed provisions are given in Article 10.4 of GB150.4-2011, on page 336. Requirements are also stated in 3.2.10.2.2.4 on page 24 of TSG 21-2016
