A-type socket-weld flange could only be used under lower pressure for its rigidity was small; B-type socket-weld flange was fit for large-size situation as its rigidity was relatively larger; the welding neck flange’s stiffness was the largest which could endure highest pressure because of the awl-shaped neck.
在三种类型的设备法兰中,甲型法兰刚性较差,仅能应用于压力等级较低的公共场所;乙型法兰筒体免受法兰变形产生的附加弯矩且刚度较高,适应较大尺寸场合;长径对焊法兰刚度最大,可承受更高压力。
