City gas polyethylene pipe safe operation maintenance realization method and system

Abstract

The invention discloses a city gas polyethylene pipe safe operation maintenance realization method and a system. The method comprises the following steps: when a leakage hole on the surface of a polyethylene pipe to be repaired is detected, two ends of a pipe to be cut on the polyethylene pipe to be repaired are surrounded by metal wires for grounding; a pipe clamper is fixed in an appointed distance from the leakage hole, and is locked; a raw edge of the pipe to be cut is opened, the pipe to be cut is cut off, and the length of the pipe to be cut is obtained; a replacement pipe as long as the pipe to be cut is put in the position of the pipe to be cut, electric melting sleeves are fixed at two ends of the replacement pipe, and the replacement pipe is welded on the polyethylene pipe to be repaired through an electric melting welding machine; and the pipe clamper is taken down. The method realizes timely adoption of protection measures in places easy to generate accidents, enables pipelines from damaging and leaking through exposure, and realizes safe operation maintenance of pipes.

Description

technical field [0001] The invention relates to the technical field of gas pipelines, in particular to a method and system for implementing safe operation and maintenance of polyethylene pipelines for urban gas. Background technique [0002] With the innovation of pipeline technology and the popularization of natural gas in various places, high-density polyethylene pipes (PE pipes) are becoming more and more popular due to their excellent quality. Most gas companies have chosen PE pipes as gas pipelines. With the laying of a large number of PE pipelines, problems such as gas leakage have also appeared in the actual operation of the PE pipeline network. In order to better maintain the normal operation of the PE pipeline, it is necessary to repair it in time when the PE pipeline leaks. At present, due to poor inspections or failure to take protective measures in time at accident-prone locations, pipelines are exposed to leaks, damage and leakage, which is extremely detrimental...
