For tube sheets with a Q345R base layer and surfacing of S30408, what technical requirements should the tube sheets meet as specified in the drawings?

Broadly speaking, there are those related to the base layer, those related to the multi-layer structure, and those related to pipe ends

Please advise on the requirements for single-layer and multi-layer versions. Thank you

Chemical composition (surface 2 mm), weld layer thickness, weld width, surface finish, number of weld layers (at least two or three layers), etc
