Abstract

The invention discloses an internal rising type flange positioning tool. The internal rising type flange positioning tool comprises a longitudinal fixed rod, a first cross rod, a second cross rod anda telescopic mechanism, wherein the end part of the first cross rod is slidably connected to the longitudinal fixed rod, the end part of the second cross rod is fixedly connected with the longitudinalfixed rod, and the telescopic mechanism is arranged between the first cross rod and the second cross rod; and a movable supporting mechanism is further arranged on the first cross rod. By adopting the internal rising type flange positioning tool, internal rising type simultaneous supporting a flange and a pipeline is realized, the counterpart precision in flange and pipeline welding or in flangewelding and pipeline welding is improved, the labor cost is reduced, and the production benefit is improved.

Description

technical field [0001] The invention relates to the technical field of pipeline welding, in particular to an internal expansion flange positioning tool. Background technique [0002] In the reconstruction or new construction of oil fields and oil and gas pipelines, the installation of valves is the most important task. Usually, at least 20 valves of various types are welded and installed on a transmission line. The flanges of the valves need to be welded to the pipes. Therefore, the welding work of the flange has become an important part of the reconstruction or new work. [0003] The welding methods of pipes and flanges are divided into the following six basic types: flat welding flanges, butt welding flanges, socket welding flanges, loose flanges, threaded flanges and integral flanges. The flange must be positioned to achieve accurate matching between the flange and the pipe to ensure the quality of the welding. At present, the positioning method when welding the flange i...
