Problems solved by technology

[0003] However, most of the conveying pipelines currently on the market are spliced ​​through flanges. Although this can play a sealing role, the installation and disassembly are relatively cumbersome. There will still be sloshing phenomenon, and when the air pressure in the pipeline is high, the pipe wall is prone to cracks, which will lead to the leakage of shale gas

Abstract

The invention discloses a shale gas conveying pipeline. The conveying pipeline comprises a first pipeline and a sealing ring, a first fastening ring is fixedly connected to one end of the first pipeline in a sleeving mode, and a protection device is clamped outside the first pipeline; a first hoop is connected to the outer portion of a second fastening ring and the outer portion of the first fastening ring in a sleeving mode, and a second hoop is connected to the position, close to the lower portion of the first hoop, of the outer portion of the second fastening ring and the outer portion thefirst fastening ring in a sleeving mode. According to the protection device, the outer portion of the first pipeline can be effectively protected, so that the pipe wall can be prevented from being cracked due to the fact that the pressure in the first pipeline is too large; according to a supporting device, the first pipeline can be effectively supported, so that the first pipeline can be prevented from shaking caused by wind power and external influence; and according to the combined use of the first hoop and the clamping hoop, the leakage of the shale gas in the first pipeline and the secondpipeline can be prevented, and on the other hand, convenience can be brought to the maintenance of workers.

Description

technical field [0001] The invention relates to the technical field of shale gas transportation equipment, in particular to a shale gas transportation pipeline. Background technique [0002] Pipeline refers to the pipeline that transports liquid and gas materials. The method of transporting materials by pipeline is called pipeline transportation. It is a transportation method that specifically transports petroleum, coal and chemical products from the production place to the market. It is the trunk line transportation in the unified transportation network. After shale gas is mined, it needs to be transported through pipelines for subsequent use. [0003] However, most of the conveying pipelines currently on the market are spliced ​​through flanges. Although this can play a sealing role, the installation and disassembly are relatively cumbersome. There will still be sloshing phenomenon, and when the air pressure in the pipeline is high, the pipe wall is prone to cracks, which...
