Abstract:

In the chemical production industry, the improper selection of gasket will not only cause the leakage at flange connections, but also affect the economic cost of supporting flanges and blots. In engineering calculation examples, there are a number of gaskets available for the same working conditions. First of all, reasonable selection should be made according to media characteristics, pressure, temperature and other working conditions, and then actual calculation should be performed according to gasket size, gasket factor and specific pressure prior to the final optimization selection, so as to avoid the cost waste caused by the excessive selection of gasket material and the unreasonable size of matching fasteners.

Key words: gasket')">

gasket, gasket factor (m), specific pressure (y), flange calculated thickness, fastener, bolt cross-sectional area.
