Section on Inspection which has information concerning non-destructive examination techniques and recommendations for their use for shell and tube heat exchangers.
Design of one pass floating heads
Design of Type-D high pressure channel closures
Weld calculations for vertical support lugs
Appendix for Repairs and Alterations of Heat Exchangers
Appendix for Clad and Overlay Construction
Appendix for Installation, Operation, and Maintenance of Shell and Tube Heat Exchangers."
