Anticorrosive wear-resistant graphene coated pipe

Abstract

The invention relates to the technical field of pipelines, in particular to an anticorrosive wear-resistant graphene coated pipe. The anticorrosive wear-resistant graphene coated pipe is prepared by the following processing steps that graphene, fluororesin, molybdenum disulfide, a solid lubricant, an amphiphilic compound, dodecyl dimethyl benzyl ammonium chloride, oleic acid hydroxyethyl imidazoline, a flame retardant, a solvent, tungsten oxide and an auxiliary agent are mixed and stirred; then heating dispersion treatment is carried out for later use; the outer surface of the pipe body to becoated and sprayed is cleaned up, the surface of the pipe body is roughly polished, and then the outer side of the polished pipe body is sprayed with a spraying agent; and the sprayed pipe body is subjected to high-temperature dissolving and sintering. According to the graphene coated pipe, the graphene coated pipe has the extremely high wear-resisting characteristic, through UMT mechanical performance and friction tests, the self-lubricating wear-resisting performance of the coating is excellent, and under the effects of the coating thickness being 50 microns and the force being 13 MPa, the coating is resistant to stainless steel ball friction for more than 200 thousand times and is not abraded through; and from the aspect of wear-resisting property comparison, the coating can ensure thata base material can work for a long time under the wear working condition.

Description

technical field [0001] The invention relates to the technical field of pipes, in particular to an anti-corrosion and wear-resistant graphene-coated pipe. Background technique [0002] Oil is a fluid mineral buried deep in the ground. At first, people called the oily liquid minerals produced in nature petroleum, the combustible gas natural gas, and the solid combustible fuel minerals bitumen. With the in-depth study of these minerals, it is realized that they are all hydrocarbon compounds in composition and are related to each other in origin, so they are collectively called petroleum. The 11th World Petroleum Congress in September 1983 proposed that petroleum is a complex mixture of gaseous, liquid and solid hydrocarbons and a small amount of impurities that exist in nature. So oil extraction also includes natural gas extraction. Oil well anticorrosion, scale inhibition, and wax removal are common problems in the production process of oil fields. With the development of o...

Problems solved by technology

Oil well anticorrosion, scale inhibition, and wax removal are common problems in the production process of oil fields. With the development of oil fields, the water content in oil wells continues to rise, and serious corrosion and scaling will occur in pipes transporting oil, which seriously affects oil fields. The production system is running normally. In addition, with the development of the oilfield, many problems such as wax plugging of the tubing, reduction of the flow area, increase of the load, and increase of the current have been caused, which seriously affect the production of the oil well.

[0003] The coating quality of most of the graphene-coated tubes on the market is average, which cannot guarantee good wear resistance of the tube body, resulting in average wear-resistant effects during use, which increases the cost of later maintenance. The quality of the surface treatment of graphene-coated tubes is average, resulting in not only the phenomenon of inorganic salts and other scale wax deposits and wax hanging on the wall during use, but also its large resistance, which is not conducive to improving the efficiency of medium transportation. Therefore, in view of the above problems Propose an anti-corrosion and wear-resistant graphene-coated tube
