Modularized skid-mounted 3PE/epoxy powder anti-corrosion pipe production line

Abstract

The invention discloses a modularized skid-mounted 3PE / epoxy powder anti-corrosion pipe production line, and relates to the field of anti-corrosion pipe production. The modularized skid-mounted 3PE / epoxy powder anti-corrosion pipe production line comprises a first spiral transmission line module, a pipe feeding rack module, a second spiral transmission line module, a flame preheating furnace module, a steel pipe outer wall impeller blasting machine module, a dust collector module, an in-pipe blowing trolley module, an in-pipe blowing dust recovery trolley module, a medium frequency heating module, a spraying extruder module, a cooling module, a pipe end processing module, an electric control module and a water cooling processing module; the medium frequency heating module is connected withthe spraying extruder module; one side of the cooling module is provided with the water cooling processing module; the pipe end processing module is arranged on one side of the water cooling processing module; and the electric control module is arranged on the side of the dust collector module. After the technical scheme is adopted, the modularized skid-mounted 3PE / epoxy powder anti-corrosion pipe production line has the beneficial effects of being reasonable in design, quick and convenient to install onsite, and capable of being directly applied to construction fields, and has the characteristics of being high in efficiency, low in investment, excellent in quality and the like.

Description

technical field [0001] The invention relates to the field of anticorrosion pipe production, in particular to a modular skid-mounted 3PE / epoxy powder anticorrosion pipe production line. Background technique [0002] In order to prevent corrosion on the outer wall of oil and gas pipelines, epoxy powder + adhesive + polyethylene (3PE) or epoxy powder (single or multi-layer) anti-corrosion coating is usually applied to the outer wall of the steel pipe. For the coating operation of pipeline anti-corrosion layer, the coating equipment is generally installed in the workshop of the factory and the anti-corrosion pipe coating operation is carried out. In the transportation of anti-corrosion pipes, it is necessary to protect the anti-corrosion steel pipes to prevent damage to the anti-corrosion layer of the steel pipes. When the anti-corrosion pipe produced in the factory is transported to the construction site, it needs to go through various transportation methods, plus lifting and ...

AI Technical Summary

Problems solved by technology

When the anti-corrosion pipe produced by the factory is transported to the construction site, it needs to go through various transportation methods, plus lifting and placing, so that the surface of the anti-corrosion pipe will inevitably be damaged, resulting in excessive on-site repairs of the anti-corrosion pipe on site, and the anti-corrosion quality of the anti-corrosion pipe will decline.

During the operation of the pipeline, due to the decline of the anti-corrosion quality, the anti-corrosion pipe is partially corroded, resulting in pipeline leakage

The service life of the pipeline is greatly reduced, causing unpredictable damage and increasing the maintenance cost of the pipeline
