Description

Technical Field

[0001] The utility model relates to the field of mechanical equipment, in particular to a flange corrector. Background Art

[0002] Flange is an important component for connecting pipes, valves, pumps and other equipment. It is usually made of round or square metal plates with a series of fixing holes and threaded holes for connecting pipes and equipment. Flange correction refers to the adjustment and correction of the flange during welding or installation to ensure its correct alignment and connection with the pipe or other equipment.

[0003] The existing flange corrector is to place one side of a right-angle steel ruler close to one side of the flange and the other side close to one side of the steel pipe, and adjust the position of the flange and the steel pipe according to the indication of the right-angle steel ruler to make them vertically aligned with the right-angle steel ruler. Since the use of the right-angle steel ruler to measure the verticality of the flange and the steel pipe requires multiple comparisons and adjustments, it is rather cumbersome, which affects the welding efficiency of the flange and the steel pipe and is rather inconvenient.

[0004] Therefore, it is necessary to design a flange corrector that can quickly correct the flange and improve the welding efficiency of the flange and the steel pipe. Utility Model Content
