Pressure and output limitations of shell type boilers. The stresses that may be imposed on the boiler are limited by national standards. Maximum stress will occur around the circumference of a cylinder. This is called 'hoop' or 'circumferential' stress. The value of this stress can be calculated using Equation 3.2.1
