Issues related to the design pressure of true capacity containers
Thread Content
According to HG-T20570, the design pressure of a jacketed vacuum vessel with internal pressure inside the jacket is as follows:: question: If the vacuum vessel is changed from a jacket to an external half-pipe, does the design pressure of the vessel also need to be designed according to the external pressure vessel?
No, the inner diameter of the outer half pipe can be basically ignored when calculating the external pressure length.
No, the coiled tube has a strengthening effect on the cylinder.
Probably not. The diameter cannot be reached.
According to the design and calculation specifications for chemical containers, external pressure is not considered for half-pipe jackets. The half pipe has a strengthening effect
There is something wrong with the poster's concept or the content of the screenshot. Whether it is a whole or half-pipe jacket, the design pressure of the inner cylinder is determined by the working pressure of the inner cylinder. Calculating pressure is another story. Chapter 2 of HG/T20582-2020 covers the calculation of half-pipe jackets.
