(DOC) Design of Pressure Vessels

The test if often carried out at a pressure higher than the design pressure as well as the maximum working pressure. It is rated so as to develop in the weakest vessel portion stresses equivalent to the yield stress of the material of construction. The hydrotest pressure is obtained by multiplying the MWP by a factor greater than 1.

Typically, this "design" pressure will be set by the set pressure of an upstream relief device, or the maximum pressure that can be developed by the upstream source (pump, compressor, or wellhead). Because pressure breaks occur at isolation valves, careful placement of isolation valves must be considered in multipressure piping-system designs.
