A stress-digesting plastic pipe inside

Abstract

The invention relates to the technical field of pipeline transportation, in particular to a stressed internal digestion plastic pipeline. The invention comprises an outer pressure-bearing pipeline and an inner force-bearing pipeline, a stress relief device is arranged between the outer pressure-bearing pipeline and the inner force-bearing pipeline, an outer fixing bar groove is opened inside the outer pressure-bearing pipeline, and the outer surface of the inner force-bearing pipeline There is an internal fixing bar groove, and one end of the outer pressure-bearing pipe and the inner stress-bearing pipe is provided with a baffle ring of the elimination device, and the upper surface and the lower surface of the baffle ring of the elimination device are equipped with an outer fixing bar fixing block and an inner fixing bar fixing block. The outer side of the baffle ring of the elimination device is fixedly connected with the outer baffle ring, and a support plate is provided between the outer pressure-bearing pipe and the inner stress-bearing pipe to solve the existing stress-relieving pipe is a rigid buffer to absorb stress Pipelines that have poor digestion and absorption capacity for stress are inconvenient to install and disassemble. Pipelines that have already appeared to digest and absorb stress are inconvenient in fixing positions and transporting pipelines, and installation is troublesome.

Description

technical field [0001] The invention relates to the technical field of pipeline transportation, in particular to a stressed internal digestion plastic pipeline. Background technique [0002] A pipeline is a device that can transport substances. When the pipeline transports substances, a kind of stress will be generated and transmitted to the pipeline. If the stress is large, the shape of the pipeline can be changed and the life of the pipeline can be reduced. The existing stress relief methods The pipe is a kind of rigid buffer and stress-absorbing pipe. The ability to absorb and absorb stress is not strong. It is very inconvenient to transport the pipeline and troublesome to install. In view of this, we propose a stress-digesting plastic pipeline. Contents of the invention [0003] The purpose of the present invention is to provide a stress-digesting plastic pipe to solve the problem that the existing stress-relief pipe proposed in the above-mentioned background technolo...

Problems solved by technology

[0003] The purpose of the present invention is to provide a stress-digesting plastic pipe to solve the problem that the existing stress-relief pipe proposed in the above-mentioned background technology is a hard buffer and stress-absorbing pipe, and the ability to digest and absorb stress is not strong, and It is very inconvenient to install and disassemble. At present, there have been pipelines that can digest and absorb stress well, but it is very inconvenient to fix the position and transport the pipeline. It is a troublesome problem during installation.
