However, in actual construction, due to the long and relatively large diameter of the welded pipes and the often narrow construction space, it is relatively difficult to align the two pipes, and it usually requires 2-3 people to assist in the alignment of the pipes. This operation is time-consuming and inefficient, often causing delays in construction schedules, consuming a large amount of manpower, electricity, and material resources, and increasing production costs. This seriously increases the additional expenses burden on enterprises and makes them lose market competitiveness. Utility Model Content
