Description

Technical Field

[0001] The present invention relates to the technical field of polyethylene cold-wrap tapes, and particularly to a polyethylene cold-wrap tape winding machine for petrochemical oil and gas pipelines. Background Art

[0002] Before a petrochemical oil and gas pipeline is put into use, it needs to be processed by winding a polyethylene cold-wrap tape on the outer side. The application of polyethylene cold-wrap tapes is very extensive. It is applicable to steel pipes of various diameters. Especially in the anti-corrosion treatment of oil and gas pipelines, polyethylene cold-wrap tapes are widely used. Its installation process is simple. Just wind the cold-wrap tape around the surface of the steel pipe at a certain angle to ensure no air bubbles and no overlap, and an ideal anti-corrosion effect can be achieved. This cold-wrap process not only saves time and labor costs, but also can be carried out at a relatively low temperature with strong adaptability. After retrieval, the patent with the publication number CN206579130U discloses a polyethylene cold-wrap tape winding machine for pipelines, which requires a separately equipped device to support and rotate the petrochemical oil and gas pipeline to ensure the winding of the polyethylene cold-wrap tape. The two need to be adjusted to ensure the winding of the polyethylene cold-wrap tape on the petrochemical oil and gas pipeline. The debugging before winding is time-consuming. Therefore, it is necessary to design a polyethylene cold-wrap tape winding machine for petrochemical oil and gas pipelines that can conveniently synchronize the rotation of the petrochemical oil and gas pipeline and the winding of the polyethylene cold-wrap tape, save the time for debugging with two machines equipped, and at the same time facilitate the unloading of the petrochemical oil and gas pipeline after winding.
