It is the basis for the pressure setting of the pressure relieving devices protecting the vessel.The design pressure may be used in all cases in which calculations are not made to determine the value of the maximum allowable working pressure. In the document AB-516,ABSA defines maximum allowable working pressure (MAWP) as:Hoop Stress - an overview ScienceDirect TopicsThe radial stress R varies across the pipe wall from a value equal to the internal pressure,p i,on the inside of the pipe wall,to a value equal to the external pressure,p e on the outside of the pipe.The magnitude of the radial stress is usually small when compared with the longitudinal and hoop stresses; consequently it is not specifically limited by the design codes.Flow assurance work processhigh-pressure vessels.
