[0002] Metal welded corrugated pipe is a very important flexible sealing element, widely used in aerospace, semiconductor manufacturing, petrochemical industry, nuclear industry and precision instruments and other fields. Its core role is to maintain system airtightness while compensating for axial, radial and angular displacement, absorbing mechanical vibration and thermal deformation, and can adapt to harsh working conditions such as high vacuum, high and low temperature and corrosive medium, hydraulic forming and welding forming, which is formed by a single thin-walled pipe blank in the mold by high-pressure liquid bulk forming. The process is high in efficiency and has no weld, but its shortcomings are that the single pipe length is limited, it is difficult to manufacture large displacement and multi-wave number corrugated pipes, and the ductility and uniformity of the pipe material are extremely high, and the wave depth and wave distance are also limited by the mold. Welded corrugated pipe (i.e. metal welded corrugated pipe) is formed by a series of welding processes to connect a plurality of pre-punched annular diaphragms (Diaphragm) with alternating inner and outer edges and precise centering. The inner edge welds form an inner cavity, and the outer edge welds form an outer cavity. This process breaks through the length limit of the pipe blank, and can flexibly manufacture corrugated pipes of any wave number and large compensation by increasing the number of diaphragms, and the wave shape and performance are easier to control, and has become the mainstream manufacturing method of high-performance corrugated pipes.
