| Abstract: | In order to improve the reliability of the expansion joint between the tube end and the tube sheet of the tube-and-shell heat exchanger,the author analyzes the stress in the course of tube expansion, thinks that the clearance between expansible tubes and the distance between holes,stipulated by GB151 - 89,are a bit too large and should be noted in practical application, and proposes a calculation formula for C-the optimum clearance before expansion jointing. |
