Emergency repair method for multi-reinforced steel-plastic composite pipe

Abstract

The invention discloses a multi-strengthened steel-plastic composite pipe emergency maintenance device and method, and belongs to the technical field of pipeline repairing. The multi-strengthened steel-plastic composite pipe emergency maintenance device comprises an upper shell, a lower shell and fasteners connected with the upper shell and the lower shell, and the upper shell and the lower shellwrap a leakage point on the outer wall of a pipeline through the fasteners; a pouring opening is formed in the middle of the upper shell or the lower shell and corresponds to the leakage point on theouter wall of the pipeline, the middle of the upper shell and the middle of the lower shell are provided with grooves for containing a plugging agent, and the pouring opening is arranged at the grooves; and the bottom of the lower shell is provided with gas vents, and gas can be exhausted conveniently when the plugging agent is poured. The leaked position of the outer all of the pipeline is wrapped with the upper shell and the lower shell at first, the plugging agent is poured into the grooves in the middles of the upper shell and the lower shell through the pouring opening by a plugging machine, and plugging maintenance of the pipeline is achieved. Through the multi-strengthened steel-plastic composite pipe emergency maintenance device and method, on-line emergency maintenance can be conducted on the leakage point of the pipeline, normal operation of production is ensured, and the production efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of pipeline repair, and in particular relates to a repair method for a multi-reinforced steel-plastic composite pipe. Background technique [0002] In modern continuous production, pipeline leakage often requires the entire line to be shut down, which not only affects the normal operation of the production line, but also seriously affects economic and social benefits. In order to prevent further leakage without affecting medium transmission, the emergency repair technology of pipelines is extremely important for the safe maintenance of pipelines. [0003] The multi-reinforced steel-plastic composite pipe is a composite pipe made of steel belt, steel mesh and its combined structure as reinforcement, co-extruded with polyethylene to form a composite strip, and then wound. The multi-reinforced steel-plastic composite pipe has spiral vertical ribs on the outer wall of the pipe, so the traditional half-section e...

AI Technical Summary

Problems solved by technology

The multi-reinforced steel-plastic composite pipe has spiral vertical ribs on the outer wall of the pipe, so the traditional half-section repair cannot be used, so the repair problem of the multi-reinforced steel-plastic composite pipe has not been well solved.
