Is the welding method for the reboiler tube sheet and shell appropriate? Node II

Reply #22019-01-10

Node II is designed in accordance with Figure a) of Appendix I I.2 of GB/T151-2014 for a tube sheet that does not serve as a flange, and it must meet the requirement that the design pressure is ≤ 4 MPa.

This is a structure that is permitted by the standards; what is the owner worried about?

If the medium causes crevice corrosion in the material, do not use such a structure.

If you are concerned about fluid accumulation, you can request a seal weld on the inner side of the tube section

The tube sheet is joined to the end of the cylinder via a short joint; this joint can be fabricated as a stiff short joint and then welded to the cylinder
