Abstract

The invention provides a pipeline connector device. The pipeline connector device comprises a pair of fixing slips. The pair of fixing slips is composed of multiple slips plates which are sequentially spliced in the circumferential direction of the fixing slips. Each slips plate is wrapped around a first pipe body and a second pipe body to be connected. At least one slips plate is provided with a first locating piece used for being inserted into a first locating hole of the first pipe body for locating. At least one slips plate is provided with a second locating piece used for being inserted into a second locating hole of the second pipe body for locating. The pipeline connector device solves the problem that in the prior art, large safety risk exists when a hot work joint manner is adopted.

Description

technical field [0001] The invention relates to the field of oil exploitation, in particular to a pipeline connector device. Background technique [0002] At present, in the daily production and operation of oilfields, oil and gas metal pipelines are prone to corrosion and scaling and pipeline leakage due to long-term operation and the influence of high-temperature, high-pressure, and highly corrosive fluid media, which will affect the safe operation of pipelines. [0003] When repairing and replacing damaged pipelines, conventional maintenance methods often require hot-fire joints, especially in gathering stations and oil-gas-intensive places, where there is a risk of fire and explosion when performing hot-fire operations. [0004] In addition, in order to meet the fire safety conditions, it is necessary to invest a lot of manpower and material resources in pre-construction preparations, and with the increase of the fire level, the requirements are becoming more and more st...
