Problems solved by technology
[0007] In order to solve the above-mentioned technical problems, the present invention provides a centralized gas supply pipeline for urban natural gas to solve the problem that the existing natural gas supply pipelines are mostly double-layer structures because they need to play a role in heat insulation, but their firmness is low. Poor, the pipeline may be damaged and deformed due to vibration during transportation, and there are some directly exposed cracks at the joints of the pipeline after assembly and connection. In rainy weather, part of the rainwater will flow through these cracks to the inside of the joint, which may It will cause corrosion on the joints and affect the normal service life of the pipeline

The invention provides a centralized gas supply pipeline for city and town natural gas. The centralized gas supply pipeline for the city and town natural gas comprises a first connector, a buffering sleeve and a second connector; the outer side of an inner shell is fixedly provided with a layer of pipeline supporting strip in a welded manner; and the first connector is fixedly arranged on one sideof an outer shell. Due to the arrangement of the first connector and the second connector, the service life can be prolonged easily; during gas supply pipeline assembling, firstly, the first connector on one side of one gas supply pipeline is embedded into a groove in one side of the second connector on one side of another gas supply pipeline; then connecting and fixing are achieved through connector fixing bolts; due to the fact that the two sides of each second connector are each of a smooth slope-shaped structure shrunk towards the inner side and the second connector can completely wrap the first connector after assembling of the first connector and the second connector, rainwater can also flow to the two sides of the second connector even in rainfall weather, the situation that rainwater is splashed to the connector position hardly happens, rusting of the rainwater to the connector position can be effectively avoided, and the service life of the pipeline is prolonged.
Description
technical field [0001] The invention belongs to the technical field of gas supply equipment, and more specifically relates to a centralized gas supply pipeline for urban natural gas. Background technique [0002] Natural gas is one of the safer gases. It does not contain carbon monoxide and is lighter than air. Once leaked, it will spread upward immediately, and it is not easy to accumulate to form explosive gas, which is relatively safe. The use of natural gas as energy can reduce the amount of coal and oil used, thus greatly improving environmental pollution; as a clean energy source, natural gas can reduce sulfur dioxide and dust emissions by nearly 100%, reduce carbon dioxide emissions by 60% and nitrogen oxide emissions 50%, and help to reduce the formation of acid rain, relieve the global greenhouse effect, and fundamentally improve the quality of the environment. Now natural gas supply in cities is very common. [0003] For example, the patent application number is 2...
