Description
Forming equipment and process of high frequency straight seam welded steel pipe with intelligent frequency modulation function technical field The present invention relates to the straight seam welded steel pipe processing technical field, be specifically the high frequency straight seam welded steel with intelligent frequency modulation function Tube forming equipment and process. Background technique
[0002] A straight seam steel pipe is a steel pipe with the weld seam parallel to the longitudinal direction of the steel pipe. Usually divided into metric electric welded steel pipe, electric welded thin-walled pipe, variable compressor cooling oil pipes, etc. Straight seam welded pipe production process is simple, high production efficiency, low cost, rapid development, high frequency welded pipe unit Using steel coils as raw materials, through a series of longitudinal deformation processes, the strip steel is deformed into an open round tube, which is passed through ...
