Design Method for Sealing Head of Internal Pressure Vessels in Chemical Industry

Abstract:

As an important apparatus of pressure vessel, sealing head, has an important role in petroleum industry, chemical industry and atomic energy industry. Sealing head of internal pressure vessels can be divided into three main types, which are convex head, conical needles head, flat head, respectively. Different heads have different calculating method to get the basic parameters and the most design formula of heads are established on the basis of membrane of the stress, and add the stress enhancement factor into the formula for the stress of the edge.therefore. In this study, the author have listed the calculating equations of the typical heads. At last, the author puts forward an example of head calculation to demonstrate the design method
