[0002] The most common method of butt-joining steel pipes is welding, which can make steel pipes more stable and firm. With the advancement and vigorous development of advanced science and technology, the technology of steel pipe welding has achieved large-scale leapfrog development in the past decade of this century, which has directly driven the production efficiency of welded pipes. The quality of welded pipes themselves has been significantly improved on the original basis. Although there is a significant improvement in technical quality, for the fiercely competitive market, the quality requirements for welded pipes are even higher.

[0003] The existing steel pipe butt joint device is to buckle two semicircular fasteners on the periphery of the two steel pipes to be welded, and adjust the alignment of the two steel pipe ports by adjusting bolts; however, the inner diameters of the two semicircular fasteners must be equal to the outer diameters of the two steel pipes to ensure that the fasteners can clamp the steel pipes. Therefore, the semicircular fasteners can only clamp steel pipes of one diameter. If steel pipes of different diameters need to be welded, the fasteners need to be replaced, and the applicability is poor. Utility Model Content
