Under Division 2, the pressures used for the design of each component are very similar to those discussed for Division 1, although terminology differs. The…

The actual thicknesses of the various vessel components will usually be thicker than the thickness calculated using the component design pressure (P). It is usually…
The process design may indicate a large pressure drop (DP) through the vessel that should be considered in the design of each vessel component. If…
Although the design pressure (Pd) establishes the basis for the design of a vessel, it is not always the pressure used for designing components of…
The maximum operating pressure (Po), specified by process design engineers, is the maximum internal pressure that will occur under normal process conditions. The design pressure…
The maximum allowable working pressure (MAWP) is required to be displayed on a pressure vessel’s nameplate, and is defined in the Code as, “the maximum…
The following pressures must be considered in the design of a pressure vessel: • Operating pressure • Design pressure • Maximum allowable working pressure (MAWP)…
The following design conditions for a pressure vessel must be established before the actual design begins: • Design pressure • Design temperature • Wind and…
Experimental research that compares conical and cylindrical shells has shown that the buckling of a conical shell is similar to that of a cylindrical shell…
The knuckles of elliptical and torispherical heads under external pressure are in tension. The critical region of these heads with regard to buckling under external…
