Abstract

The invention relates to the technical field of pipeline production, in particular to a heat-preservation durable gas pipeline and a preparation technology thereof. The heat-preservation durable gas pipeline comprises a gas pipeline body, an outer layer sleeve and annular connecting pieces. The gas pipeline body sequentially comprises an inner layer pipe blank, a heat-preservation interlayer and an outer layer pipe blank from inside to outside. An anti-corrosion coating is sprayed on the outer wall of the outer layer pipe blank. A water-proof coating is sprayed on the inner wall of the inner layer pipe blank. The heat-preservation interlayer is embedded between the inner layer pipe blank and the outer layer pipe blank. The inner layer pipe blank and the outer layer pipe blank are connectedthrough the annular connecting pieces welded to the left ends and the right ends of the inner layer pipe blank and the outer layer pipe blank. The outer layer sleeve is fixed to the outer layer pipeblank in a sleeving mode. According to the heat-preservation durable gas pipeline and the preparation technology thereof, the heat-preservation property of the gas delivery pipeline can be improved significantly through the heat-preservation interlayer, and the gas delivery efficiency is improved; and the prepared pipeline has the high acidic medium etching resisting capability by using quartz powder and nano-zinc oxide in the outer layer sleeve, and accordingly the service life of the gas pipeline is prolonged.

Description

technical field [0001] The invention relates to the technical field of pipeline production, in particular to a heat-insulating and durable gas pipeline and a preparation process thereof. 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 add...
