Pipe protection device

Abstract

The invention provides a pipe protection device which comprises a packaging bag body. An anti-corrosion coating which coats the outer side of a working pipe is included, the outer side of the anti-corrosion coating is sleeved with an anti-bending supporting corrugated pipe, a sinking part of the supporting corrugated pipe is sleeved with a buffer ring, the outer diameter of the buffer ring is larger than the outer diameter of the corrugated pipe by 2 mm-3 mm, and the outer side of the buffer ring is coated with an outer protective layer; and the supporting corrugated pipe is made of thermoplastic polyurethane engineering plastic, the buffer ring is made of polyurethane rubber, and the outer protective layer is made of modified polyvinyl chloride plastic or galvanized steel strips. The pipeprotection device has the beneficial effects that the working pipe is prevented from water or oxygen molecule corrosion through the anti-corrosion coating; the supporting corrugated pipe enables theworking pipe to be well supported, the good protection effect on the working pipe is achieved, the free bending characteristic is given to the supporting corrugated pipe by means of the self structure, the buffer ring enables the supporting corrugated pipe to be free of direct friction of the supporting corrugated pipe during bending, the abrasion degree is reduced; and the outer protective layerhas the good protection function on all internal function layers.

Description

technical field [0001] The invention relates to the technical field of organic material products, in particular to a pipeline protection device. Background technique [0002] Fluid transportation is one of the common processes in life and production. Generally, fluids are transported through pipelines. The pipeline needs to be laid according to the actual situation, which requires some connecting elbows to connect straight pipes to make the pipeline bypass obstacles. The laid pipeline needs to be equipped with protective devices on the outside, so that the service life of the pipeline can be significantly extended. The traditional method is to coat the outside of the pipe with paint to prevent water and oxygen molecules from corroding the surface of the pipe. Such simple protective measures cannot achieve the purpose of resisting external impacts, so once the weather or other equipment exerts an impact on the pipeline, the pipeline may bend or even break. [0003] It can...
