In Pressure Vessel, When U stamp is required?

[MohdYaseen2010]

Normally most of the pressure vessel are designed according to ASME VIII whether with it has a U Stamp or without U Stamp, my question: when vessel shall be designed for U Stamp & when shall be exempted from the U Stamp?

This is discussed in the previous threads in the Forums. Also, can check ASME VIII section U-1 for details.

Very simply when the Jurisdiction or Purchaser requires stamping.
