Re: [MW:29851] vertical vessel piping _first rest support

did you run flexibility calculations? If you get zero reactions at this support for all loading conditions including pressure test, then you may remove it

Dear all,

  Please find the below, sulfur absorber vessel, The following pipe mtl is A335 P11 and thk. = 14.27mm. The vertical portion is 3.8m only, immediately on the rack we have rest support

   If the vertical portion is long i.e if it about 15m and above, we have to provide rest support either rigid or spring in vertical portion.

As per below snap small vertical vessel and the pipe size 12" sch 60 we have more span. Providing support and if not in the vertical portion doesnt impacting the nozzle loads. The nozzle loads are Fx=Fy=Fz=18Tons and Mx=15tons, My=Mz=7tons. In my point of view first rest support is not required in this case, kinldy share your opinions
