Protective device for pressure pipeline

Abstract

The invention discloses a protective device for a pressure pipeline. The protective pipeline includes the pressure pipeline. Support steel bars are vertically welded to the outer side surface of the pressure pipeline. An outer protective steel pipe is vertically welded to the other end of each support bar. The pressure pipeline and the support steel bars are located in the cavity of the outer protective steel pipe. Connection flanges are fixedly welded to the two ends of the outer protective steel pipe. Connection part protective rings are arranged on the outer sides of the connection flanges.The connection part protective rings match the connection flanges. The connection part protective rings are connected to the outer side surface of the outer protective steel pipe. The protective device for a pressure pipeline has the advantages of simple structure, reasonable design, simple operation and convenient use. Through the arrangement of the outer protective steel pipe and the support steel bars, the protective device for a pressure pipeline is provided with a layer of vacuum zone between the pressure pipeline and the outer protective steel pipe under the coordination of the outer protective steel pipe and the support steel bars, which greatly protects the pressure pipeline. The protective device for a pressure pipeline has a broad application prospect.

Description

technical field [0001] The invention relates to a protection device for a pressure pipeline, in particular to a protection device for a pressure pipeline, which belongs to the technical field of pipeline protection. Background technique [0002] In a broad sense, a pressure pipeline refers to all pipelines that are subject to internal or external pressure, regardless of the medium in the pipeline. The pressure pipeline is a part of the pipeline, and the pipeline is used to transport, distribute, mix, separate, discharge, measure, control Assemblies consisting of pipes, fittings, flanges, bolted connections, gaskets, valves, other components or pressure parts and supports that prevent fluid flow. [0003] Most of the existing pressure pipeline protection uses protective cotton to wrap the pressure pipeline, so that only the surface of the pressure pipeline is protected, and the collision of the pressure pipeline cannot be avoided. At the same time, the existing protection dev...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing pressure pipeline protection uses protective cotton to wrap the pressure pipeline, so that only the surface of the pressure pipeline is protected, and the collision of the pressure pipeline cannot be avoided. At the same time, the existing protection device for the pressure pipeline has no sewage discharge structure. A large amount of impurities will be deposited inside the pressure pipeline, which will shorten the service life of the pressure pipeline on the one hand, and affect the cleanliness of the substances transported by the pipeline on the other hand, which is far from meeting the current people's requirements for this product
