Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel pipe straightening, in particular to a multi-diameter galvanized round pipe straightening device. Background Art
[0002] Round tube refers to steel with openings at both ends and a hollow concentric cross-section, with a large ratio of length to circumference. It can be used for pipelines, thermal equipment, mechanical industry, petroleum geological drilling, containers, chemical industry and special purposes.
[0003] However, during the use of galvanized round tubes, the ends of the round tubes are usually deformed due to extrusion, collision, etc., so that the cross-section becomes an elliptical structure, affecting the normal use of the galvanized round tubes.
