本文通过对管壳式换热器在制作过程中所提到的管子与管板之间进行“强度焊+贴胀”的技术要求,考虑到管子数量、管板厚度以及施工工期,选用了液压胀接工艺。在保证质量的同时,大大缩短了工作时间。 This paper through the shell and tube heat exchanger in the production process mentioned between the tube and the tube plate between the “strength welding + inflation” technical requirements, taking into account the number of tubes, tube thickness and construction period, the selection The hydraulic expansion process. While ensuring the quality, greatly reducing the working hours.
