Technical Field

[0001] The utility model relates to the field of pipe fitting processing, in particular to a multi-faceted clamping device for pipe fittings. Background Art

[0002] Steel pipe fittings are all pressure-bearing pipe fittings. According to different processing techniques, they are divided into four categories, namely butt-welding pipe fittings (with and without welds), socket welding and threaded pipe fittings, and flange pipe fittings. When processing pipe fittings, the pipe fittings need to be fixed first and then processed. At this time, a pipe clamping mechanism is needed to fix the pipe fittings.
