Description

Technical Field

[0001] The utility model relates to a multi-stage pipe header for steel pipe processing, belonging to the technical field of pipe header equipment. Background Art

[0002] A multi-stage pipe header for steel pipe processing is a device used for steel pipe processing, mainly for rolling one end of a steel pipe to make it reach the required shape and size. After retrieval, it is found that the Chinese patent with the publication number CN205110353U discloses a pipe header mechanism for high-pressure steel pipe processing.
