Description

Technical Field

[0001] This utility model relates to the field of steel pipe processing technology, specifically to a device for straightening bent steel pipes. Background Technology

[0002] Steel pipes refer to steel materials with a hollow cross-section, whose length is much greater than its diameter or circumference. According to the cross-sectional shape, they are divided into circular, square, rectangular, and irregularly shaped steel pipes. According to the production process, they are divided into seamless steel pipes and welded steel pipes. Seamless steel pipes are further divided into hot-rolled and cold-rolled types, while welded steel pipes are further divided into straight-seam welded steel pipes and spiral-seam welded steel pipes. Existing steel pipes can be recycled and refurbished for reuse. However, steel pipes are prone to bending under external forces during use. Bending steel pipes need to be straightened before they can be reused. To address the above problems, this application designs a bending steel pipe straightening device. Utility Model Content
