The Stress Analysis of New Pressure Piping Model


Article Preview

High-pressure becomes the high pressure unit design main consideration factor to compressive load capacity, security, efficiency, economic and manufacturing process of high-pressure equipment. This article proposes a new pressure piping according to the current high-voltage device development tendency and the future requirement. This new type of pressure pipe can be simplified for pipe casing model. Firstly we establish single, double and multilayer pressure piping model. We push out the multilayer pressure pipe stress formula according to stress situation of the analysis of the knowledge of mechanics of each model. We get this pressure piping withstand by the most intrinsic pressure enhance obviously under each layer within the radius of the cylinder reach the initial limitation of materials and other parameters of model are same through the comparison of the theoretical formula calculation with other general. Pressure pipeline calculated value. The multi-layer pressure piping system's circum radius are smaller than other piping with other pressure piping withstand the same most intrinsic pressure and the most interior radius are the same situation.
