Analysis of Bolt Holes Weakening the Strength on End Cover Flange of High Pressure Vessels
NI Yong-liang;CAO Cun;Jiangsu Chemical Equipment Manufacturing and Installation Co.,Ltd.;
The force condition of the end cover flange of the high pressure vessel and the influence of the bolt holes on weakening the strength of the flange were analyzed to indicate that,the flange strength determined by the Waters method is suitable for low medium pressure flanges with common diameter,but for the end cover flange of the high pressure vessel,it's not applicable; as for large diameter of the high pressure vessel,their design pressure is very high,the equivalent stress consisting of bending stress and shear stress at this section should be checked.
