Fuel gas conveying pipeline

Abstract

The invention provides a fuel gas conveying pipeline which comprises an inner layer, a middle layer and an outer layer. The inner layer is a waterproof and anti-oxidation pipe blank metal layer. The middle layer is a PET heat preservation layer. The heat preservation layer comprises an inner PET layer, a heat preservation layer body and an outer PET layer. The outer layer is an alloy layer, and the thickness of the fuel gas pipeline is 0.5-4 cm. The service life of the fuel gas conveying pipeline is effectively prolonged, oxidization and corrosion of organic substance to the interior of the fuel gas pipeline are reduced, the pressure bearing ability of the fuel gas conveying pipeline is improved, meanwhile, the production cost of the pipeline is reduced, meanwhile, direct irradiation to the fuel gas pipeline by sunlight is reduced, the risk of aging of the fuel gas pipeline is reduced, the durable effect of the fuel gas pipeline is improved, and use safety is improved.

Description

technical field [0001] The invention relates to a gas pipeline, in particular to a gas delivery pipeline. Background technique [0002] Industry has always been known as the leading industry of the national economy. China's industry is mainly based on basic industrial sectors. Including energy industry, iron and steel industry, machinery industry, etc. It mainly includes three sectors: coal, oil and gas, and electric power. Since the development and production conditions, production process and transportation conditions of the three are different, the production layout has its own characteristics. The quantity, quality, variety, development conditions and distribution of coal resources determine its development scale and growth benefits, and restrict the possibility of coal industry development and its regional and national status. Whether a coal field can be developed or prioritized, in addition to capital allocation conditions, economic location also has an important i...

Problems solved by technology

However, the thermal insulation performance of the gas transmission pipeline prepared by the prior art is relatively poor, which makes the gas transmission efficiency in the pipeline lower due to the lower temperature in the pipeline when the weather is relatively cold; moreover, the pipeline is exposed to the air for a long time , the metal components on the surface are corroded under the action of water vapor in the air, which shortens the service life of the pipeline, and at the same time, the inside of the pipeline is easily corroded by organic substances, which affects its anti-pressure effect
