Description :

　　Epoxy resin (epoxy powder) anti-corrosion steel pipe is mainly made of thermosetting epoxy resin as the main raw material, with air as the dispersing medium. With the help of high-speed airflow and electric charge attraction, the powder is evenly sprayed on the surface of the preheated steel pipe. Under high temperature, the powder melts into a uniformly thick anti-corrosion layer. This coating is solvent-free and does not require consideration of fire prevention measures during construction; Fast curing speed; The thickness can range from tens of micrometers to hundreds of micrometers, with good toughness and no cracks when the pipeline is bent; The advantage of its large size is that it has great adhesion to the metal surface, excellent adhesion performance, and resistance to cathodic peeling, and has "failure safety"; Easy to repair; Strong resistance to soil stress, suitable for most harsh corrosive environments such as high salt, high alkali, and cold. However, FBE is prone to impact damage, has a high water absorption rate, and has strict requirements for rust removal on the surface of steel pipes.

　　In the late 1980s, epoxy resin began to be used in small quantities for domestic directional drilling river crossing projects. In recent years, construction technology has gradually matured and the amount of epoxy used has been increasing. The area where the civil aviation Tianjin Beijing oil pipeline passes through has a developed water network and harsh corrosive environment. The project chose fusion bonded epoxy as the anti-corrosion layer. After several years of construction, cathodic protection tests were conducted on the pipeline, and the results showed that the coating had superior anti-corrosion performance, which extended the service life of magnesium and zinc anodes accordingly. This anti-corrosion layer has also been adopted in large-scale projects such as the Zhongwu gas pipeline and the Southwest refined oil pipeline. The corrosive environment requires the anti-corrosion layer to have good resistance to atmospheric aging. Overhead pipelines are exposed to atmospheric environments for a long time and can naturally corrode under wind, rain, and sunlight.

　　Epoxy powder anti-corrosion for water supply pipelinesSteel pipe manufacturerDirect sales (self-produced and self sold) are important measures to stabilize growth. It is clearly stated that the reserve requirement ratio reduction for MLF has a clear directionality, with large banks being the main targets of replacement. After adjusting the dynamic assessment criteria for the targeted reserve requirement ratio reduction in inclusive finance, major large banks may have successfully reached the second tier, which still reflects the tilt of this reserve requirement ratio reduction towards small and micro enterprises. Zhao Wei, a researcher at Changjiang Macro Bond, said, 'This reserve requirement ratio cut is similar to the operation in 2018, both of which replaced MLF.'. A 1 percentage point reduction in reserve requirement ratio will release approximately 1.5 trillion yuan, but there will be 1.44 trillion yuan of MLF due in the first quarter. After the reserve requirement ratio reduction, MLF will not be renewed upon maturity, and cheaper money will be used to replace more expensive money, guiding funds to flow towards entities and reducing their costs. In the future, under the framework of a prudent monetary policy, the central bank may further enhance the transmission efficiency of combination policy tools to the market, effectively 'drip irrigation' from multiple dimensions such as flow, direction, and term, to prevent 'flood irrigation', "said Lian Ping, an economist at Bank of Communications.

　　Epoxy powder anti-corrosion coating is composed of two main components: epoxy and powder. It is a two-component coating of A (epoxy) and B (curing agent), which has excellent adhesion, toughness, moisture resistance, water resistance, and chemical resistance. It has the function of avoiding various ions from passing through the paint film and has the characteristics of swelling and shrinkage with the coated object. The paint film never falls off or cracks. Thickness of 0.5-1.0mm. Epoxy powder is a cost-effective anti-corrosion method, and engineering tests have shown that using epoxy powder combined with cathodic protection. At the end of 20 years of use, there has been no occurrence of corrosion in oil and gas pipelines. For epoxy powder anti-corrosion coating and anti-corrosion steel pipes, precautions should be taken: In order to make the functions of anti-corrosion steel pipes more comprehensive, anti-corrosion steel pipe companies also present more and more varieties when making anti-corrosion steel pipes. Today, let's take a look at another type of anti-corrosion steel pipe from anti-corrosion steel pipe companies - epoxy powder anti-corrosion steel pipe. Among them, epoxy powder anti-corrosion steel pipe is made of epoxy resin, coal tar asphalt, anti rust pigment, additives and modified amine equipment. Moreover, epoxy powder anti-corrosion steel pipe still has the characteristics of agile drying, good adhesion, good flexibility, two-component packaging, convenient construction, acid resistance, alkali resistance, salt resistance, water resistance, oil resistance, etc. And the anti-corrosion steel pipe company also discussed its anti-corrosion characteristics and uses, among which the epoxy powder anti-corrosion steel pipe is coated with a layer of epoxy powder anti-corrosion layer on top of the anti-corrosion steel pipe. This anti-corrosion layer also combines the high mechanical strength, strong adhesion, chemical medium resistance, and water resistance, microbial resistance, and plant root resistance of epoxy resin, and is a high-performance insulation coating. This coating also has outstanding chemical resistance and water resistance, and is suitable for the anti-corrosion of equipment and pipelines in oil, gas, water pipelines, tap water, gas, pipelines, refineries, chemical plants, and sewage treatment plants. It can also be used as anti-corrosion for offshore oil drilling channels and underwater parts of ships, as well as mines, underground mines, and pipelines. Corrosion prevention of equipment.
