A method of using a tool for patching fastening in pipeline repair

Abstract

The invention discloses an application method of a tool for repair plate fastening in pipe repair. The used tool comprises a T-shaped rod, a thread disc, a connecting nut, a rotating piece and base arranged in sequence from top to bottom. As all the parts are reasonably designed, the tool can realize the dismounting and mounting process without needing special operation spanner, and the pipe repair plate fastening is quickly realized. In addition, the connecting structures of the T-shaped rod, the connecting nut and the rotating piece are reasonably designed, the several parts are more convenient and labor-saved in disassembly. The tool can fasten pipes with different shapes and different sizes. The tool can greatly improve the repair plate fastening efficiency in pipe repair; and in addition, as enough operation space is reserved around a repair plate when the tool fastens the repair plate, the continuous welding process of the repair plate can be realized, and the welding effect is good. The method can effectively improve the pipe repair efficiency.

Description

technical field [0001] The invention relates to a method for using a tool used for patching fastening in pipeline emergency repair. Background technique [0002] In the fields of electric power, oil or natural gas, transmission pipelines often cause local ruptures due to various reasons during use, and timely repairs are required. However, the usual practice in the prior art is to use a fastening tool to repair a temporary patch at the rupture. Commonly used fastening tools include two semicircular fasteners. When repairing the rupture of the conveying pipeline, it is necessary to place the repair plate in the corresponding position first, and then use the above two semicircular fasteners to fix the patch The plate is fixed on the conveying pipeline, and finally the maintenance personnel install the above-mentioned supplementary plate on the conveying pipeline by means of welding connection. However, since the size and shape of the above-mentioned fastening tools have been...

Problems solved by technology

However, since the size and shape of the above-mentioned fastening tools have been determined, they can only be applied to the emergency repair work of circular conveying pipelines of a specific size, and are not universal; Due to the limitation of the above-mentioned two semi-circular fasteners, it is difficult to extend into the bottom of the conveying pipeline, and certain processing is required to leave enough operating space for the above-mentioned fastening tools, thereby greatly reducing the efficiency of emergency repairs; in addition, Since the above-mentioned semicircular fasteners will cover the edge of the patch when the patch is pressed against the conveying pipeline, when the patch is welded, the continuous welding process of the patch cannot be realized. The edge parts not covered by the semicircular fasteners are welded well, and then the above fastening tools are removed, and then the edge areas covered by the semicircular fasteners are welded. The above welding process reduces the repair efficiency and the welding effect not good
