Seal weld and single or double groove on Type shell & tubes heat exchangers

Seal weld and single or double groove on Type shell & tubes heat exchangers

(OP)
Can somebody is this group shed some lights concerning technical information through which, I can state that double groove, single groove and seal weld is mandatory for tube to tube-sheet joint for type shell & tubes heat exchangers. Probably fluid clasification, thermal cycles and tube-sheet thickness play important role on to make technical decisions on this regard

Highly appreciated whether this big team can provide me with some information

Seal welding is not a strength weld, it is merely used to prevent leakage as opposed to single and double groove which are for strength.
