Cangzhou Bohai Professional production of 20 # flange tube sheet tube sheet, is in the steel drill pipe diameter and the same hole, the pipe penetration weld the fixed direct 20 # flange, played the role of such an accessory. In the calculation of the fixed tube plate temperature difference according to various operating conditions to calculate the axial stress case, the pull-off force of the axial stress of heat transfer tubes, tube to tube sheet between q, one can not meet When the intensity (or stable) condition, you need to set the expansion joint. In the fixed tube plate strength checking calculations, when the thickness is determined after the tube flange 20 #, no expansion joints 20 # flange quote, sometimes tube sheet strength is not enough, set up after the holiday swell, tube sheet thickness may meet Claim. In this case sales 20 # flanges, expansion joint may be provided to thin tube sheet, but from material consumption, ease of manufacture, a comprehensive assessment of the safety and economic effects may be. Fixed tube sheet heat exchanger is commonly used in U-type expansion joints, it has a simple and compact structure, compensation is good, cheap, etc. Manufacturers 20 # flanges, Cangzhou Bohai (certification), 20 # flange by the Cangzhou Bohai fittings Limited.
