Breakage repairing device and method for flexible composite pipeline

Abstract

The invention discloses a breakage repairing device and method for a flexible composite pipeline. The repairing device comprises two connectors, wherein one end of each connector is connected in a screwed mode through a movable joint, and the other end of each connector is connected with the breakage end of the flexible composite pipeline; and the joints of the connectors and the breakage end of the flexible composite pipeline are connected in a pressed mode through pressing heads by means of a hydraulic machine. The repairing method comprises the steps that the connectors are selected; the movable joints are installed in a sleeved mode; the connectors are connected with the breakage end; the proper pressing heads are selected and installed at the joints in a sleeved mode; the hydraulic machine is started to press the pressing heads; the movable joints are screwed to connect the connectors in a fastened mode; and pressure testing and backfilling are conducted. According to the breakagerepairing method for the flexible composite pipeline, the repairing strength can be guaranteed, and the breakage repairing durability of the flexible composite pipeline can be maintained. The methodis extremely high in field application performance, has the technical characteristics of being rapid, efficient, safe and environmentally friendly, is extremely good in pressure bearing effect and wide in application range and is an excellent scheme for breakage repairing of the flexible composite pipeline.

Description

technical field [0001] The invention belongs to the technical field of pipeline repair, and in particular relates to a damage repair device and method for a flexible composite pipeline. Background technique [0002] Flexible composite pipe is a kind of industrial application pipe fittings made of polymer composite materials, with certain high strength, high pressure, corrosion resistance, small friction coefficient, good heat preservation, good flexibility, long life and other excellent properties. It has a wide range of uses, mainly used in water supply, drainage, heat supply, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, hydraulic engineering and various industrial devices. [0003] The flexible composite pipe is mainly composed of an inner layer, a reinforcement layer and an outer protective layer. The inner layer is an extruded polymer layer, which keeps the internal liquid intact and prevents crushing; the reinforcement layer ...

AI Technical Summary

Problems solved by technology

[0004] As the amount of flexible composite pipes increases year by year, the number of pipe damages also increases significantly. Since the length of a single flexible composite pipe is usually relatively long, the method of replacing the entire pipeline to achieve damage repair is obviously costly. The existing technology The repair methods used for the damage of the flexible composite pipe in the current study are not very effective, and can only alleviate the damage temporarily. During high-pressure transportation, secondary leakage may be caused, resulting in safety accidents and causing huge losses to the production of enterprises. Provide a practical It is particularly important to have a flexible composite pipe damage repair process that can guarantee the repair strength and maintain the durability of the damage repair.
