The invention discloses a forming method for a film shell
pipe bundle in a module. The forming method comprises the steps of S1, material inspection and storage, S2, material receiving, S3, making ofa fixing tool, S4,
cutting blanking of film shell pipes, S5,
spot welding of a
pipe support, S6, fixing of the film shell pipes to a frame, S7, full-length
welding of the
pipe support and the film shell pipes, S8,
spot welding of a
flange, S9, full-length
welding of the film shell pipes and the
flange, S10, forming of an upper hole and a lower hole in the two ends of each film shell pipe, S11,
welding of upper vertical
branch pipes and lower vertical
branch pipes to the upper holes and the lower holes correspondingly, S12, forming of connecting holes in headers, S13, welding of the headers andthe upper vertical
branch pipes, S15, taking-off of connecting bolts between the
pipe support and the frame, S16, weld joint 100% nondestructive examination of the welded film shell pipe bundle, andS17, cleaning and pressure testing of the film shell pipe bundle. Through the forming method, the film shell pipe bundle of higher precision can be formed.
