Abstract

The invention relates to an extrusion coating constant speed control device which comprises an extrusion coating pipeline, a feeding pipe and an extrusion coating emitter. One end of the extrusion coating pipeline is communicated with one end of the feeding pipe, the extrusion coating emitter is arranged on the outer wall of the feeding pipe, and a coating device is arranged in the other end of the feeding pipe. Air with the constant flow speed is conveyed through ventilation equipment, so that the coating device moves forwards at the constant speed, and the inner wall of the extrusion coating pipeline is uniformly coated with paint; and the coating is uniform and not prone to falling off, so that the corrosion speed of the pipeline is reduced.

Description

technical field [0001] The invention belongs to the technical field of pipeline anticorrosion, and in particular relates to a uniform speed control device for extrusion coating. Background technique [0002] Pipeline anticorrosion is a protection technology to prevent pipelines from being corroded by soil, air and transport media (oil, natural gas, etc.). Most of the pipelines for transporting oil and gas are located in complex soil environments, and the transported media are mostly corrosive, so the inner and outer walls of the pipelines may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which will not only interrupt the transportation, but also pollute the environment, and may even cause fire and harm. Description of Pipeline Corrosion Phenomenon Corrosion can be understood as a chemical reaction of materials in their environment, which will cause the loss of pipeline materials and lead to failure of pipeline components or ev...
