Abstract

This invention is a pipeline rechanneling device and a method to rechannel pipelines with this device. This device includes adjutage cover and adjutage body, adjutage cover connected with adjutage body in spiro union mode. The upside of adjutage body includes adjutage body head and adjutage body neck, there is a jack bolt fixing the place of internal plug in the adjutage body head in radial direction; the middle part of the adjutage body is a hollow sphericity, two pipe segments with the diameter less than the diameter of sphere are connected with the surface of sphere in a through beeline, the middle part of sphere of adjutage body is vidied into upper part are lower part, they are connected by nut and bolt; the underpart part of the adjutage body is adjutage support, is a pipe segment going through the sphere surface of the middle part of adjutage body. This device can be used to trepanning and plugging of the pipelines, can replace the existing pipeline trepanning and plugging devices, improving the work efficiency.

Description

technical field [0001] The invention belongs to the technical field of pipeline rerouting, and in particular relates to a device for rerouting pipelines in use and a method for rerouting pipelines using the device. Background technique [0002] In order to meet the needs of long-distance transportation, the petrochemical industry, city gas industry and other fields generally use pipelines to transport oil, natural gas, liquefied petroleum gas, coal gas and other media. Under the action of self-corrosion, or artificial and other external forces, the pipeline will inevitably leak. Once a leak occurs, the pipeline must be repaired in a timely and effective manner. In order to reduce the impact on the production and life of end users, pipeline leakage repairs usually need to be carried out without stopping the transmission medium of the leaking pipeline section. [0003] Pipelines for transporting oil, natural gas, liquefied petroleum gas, coal gas, etc. are generally buried b...
