Regarding the welding method for small nozzles on flat covers
Thread Content
It is a small container with a working pressure of 0.03 and a design pressure of 0.6; the cover is a flat lid, on which pipes with a diameter of φ18X2 are welded. Is it necessary to use a fully penetrated weld structure? Is a non-through weld structure feasible in the diagram?
As for the hazard to the medium, if it is moderate or less, welding can be carried out in a manner similar to that used for PL/SO flanges; however, the pipe is too thin. For high/extreme cases, a fully penetrated fixed type can be used
With such low pressure, if it’s not a low-temperature vessel or a medium with extremely high hazard levels, and the temperature gradient is not significant, it’s sufficient to use fillet welds instead of grooves.
This requires you to design how to approach calculating the openings
