Problems solved by technology

[0004] However, the support blocks in the related art are generally wooden support blocks, which need to be manually inserted and inserted by the operator during use, so the efficiency of repairing the pipe is low, and the effect of repairing the joint is relatively poor.

Abstract

The invention discloses a support device of a pipe repaired mouth heat shrinkage sleeve, and belongs to the field of oil and gas storage and transportation. The device comprises a control module, and a slide module slidingly connected with the control module; the control module and the slide module are absorbed on the outer wall of a pipe through fixed pieces; the slide module is positioned between the outer wall of the pipe and the heat shrinkage sleeve, and is used for supporting the heat shrinkage sleeve; and the control module is positioned out of an area covered by the heat shrinkage sleeve, and is used for controlling the slide module to slide in a direction near the control module until the slide module slides out of the heat shrinkage sleeve in the shrinkage process of the heat shrinkage sleeve. The support device of the pipe repaired mouth heat shrinkage sleeve improves the pipe mouth repair efficiency, solves the problems of low pipe mouth repair efficiency and weak mouth repair effect in related technologies, and is applied to pipe mouth repair.

Description

technical field [0001] The invention relates to the field of oil and gas storage and transportation, in particular to a supporting device for heat shrinkable sleeves for jointing of pipelines. Background technique [0002] Pipeline joints are anti-corrosion structures at the welds of two sections of oil or gas pipelines, and heat-shrinkable sleeves are generally used as joint materials. During construction, the heat-shrinkable sleeve can be wrapped on the welded part of the pipe, and then the surface of the heat-shrinkable sleeve can be evenly heated to make the heat-shrinkable sleeve shrink evenly along the radial direction of the pipe. At the same time, the inner layer of the heat-shrinkable sleeve is melted. The high-quality colloid is filled and coated on the pipeline to form a firm and sealed outer anti-corrosion layer of the pipeline. [0003] In the related art, since the aperture of the heat-shrinkable sleeve is generally larger than that of the pipe, after the heat...
