Anticorrosion coating is one of the most basic methods of pipeline anticorrosion to apply the coating uniformly and compactly on the surface of the derusting metal pipeline to isolate it from various corrosive media. Since the 1970s, more requirements have been put forward for coating performance by laying pipelines in polar and ocean environments and increasing pipeline temperature due to heating and transportation of oil products. Therefore, more and more composite materials or composite structures are used for pipeline anti-corrosion coatings. Outer wall anti-corrosion coating: types of outer wall coating materials and conditions of use. Inner wall anti-corrosion coating: in order to prevent tube corrosion, reduce friction resistance, improve the throughput, and coated in the inner wall of the tube film. Commonly used coatings are amine cured epoxy resin and polyamide epoxy resin, a coating thickness of 0.038 ~ 0.2 mm. In order to ensure that the coating is firmly bonded to the tube wall, the inner surface of the tube must be treated. Since the ’70s tend to tube, outer wall coating selection of the same material, so that the tube, outer wall coating at the same time. Anticorrosive thermal insulation coating: in the pipeline of medium and small...
Corrosion prevention of pipes refers to the measures to slow down or prevent the corrosion and deterioration of pipes under the chemical and electrochemical action of internal and external media or the metabolic activities of microorganisms. Technical information A technique to protect pipelines from corrosion by soil, air, and transport media (oil, natural gas, etc.).The pipeline conveying oil and gas is mostly in the complex soil environment, and the medium conveying is also corrosive, so the inner wall and outer wall of the pipeline may be corroded. Once the pipeline is corroded and perforated, it will cause oil and gas leakage, which will not only interrupt transportation, but also pollute the environment, and may even cause fire, causing harm. According to U.S. pipeline industry statistics, direct losses due to corrosion amounted to $600 million in 1975. Therefore, preventing pipeline corrosion is an important part of pipeline engineering. Introduction to the Corrosion can be understood as a chemical reaction of materials in their environment, which can cause the loss of pipeline materials and lead to the failure of pipeline components or even the entire pipeline system. Corrosion in a pipeline system is defined as chemical reactions, electrochemical reactions, and microbial erosion...

Induction melting furnaces used in industry include crucible furnace (coreless induction furnace) and melting trench furnace (cored induction furnace). The crucible is made of refractory or steel and has a capacity ranging from several kilograms to dozens of tons. Its melting characteristic is that they melt in the crucible is subjected to electric power, forcing the liquid level of the molten pool to bulge, and the melt flows from the center of the liquid level to the periphery, causing circular flow. This phenomenon is called the electric effect, which can make the melt composition uniform. The disadvantage is that the slag is biased towards the periphery and the coverage is poor. Compared with melt trench furnace, crucible furnace has a flexible operation, high melting temperature, low power factor, and high power consumption. The inductor of the melt trench furnace consists of an iron core, an induction ring, and a melt trench lining. The melt trench is one or two belt-shaped annular trenches filled with melt connected with the melt pool. In principle, the melting trench furnace can be regarded as an iron core transformer with only one turn of the coil in the secondary and short circuit. The induced current...
With the development of science and technology and the improvement of product quality requirements, many jewelry manufacturers and handicraft manufacturers have chosen medium frequency melting furnaces to smelt non-ferrous metals, and have achieved remarkable results. So, what are the advantages of medium frequency electric furnaces in metal smelting? The actual operation of the medium frequency smelting furnace is simple, and the temperature rises quickly, and it can be opened at any time. The application of energy consumption is reduced, which can ensure the control and smooth development of the whole melting process, and relieve the troublesome work of the workers in the melting furnace. The adoption of new technologies, new materials, and new processes has improved the performance and application effects of the medium frequency furnace, showing more and more vitality, and has achieved significant social and economic benefits. The medium frequency smelting furnace adopts an automatic frequency tracking system, and the frequency can be automatically adjusted with the load change without switching the capacitor. In recent years, the medium frequency furnace adopts KGPS induction heating device, which has high component density, outstanding performance, better start-up, more reliable use, simple maintenance, small footprint, and more advanced manufacturing technology. The furnace...
The most common fault phenomenon in the use of a medium frequency furnace is that it cannot start normally. The following list of common reasons and detection methods for failure to start: 1. Thyristor breakdown, multimeter measurement, resistance are almost zero. 2. If the water-cooled cable is broken, the two ends can be stripped and connected to the two ends of the cable. If it can be started, it indicates that the cable is broken. Attention should be paid not to pull high power to avoid unnecessary danger caused by burning off the power cable with a high current. 3. The intermediate frequency transformer burns out. Measure the resistance of 1000V gear, which should be around 70. 4. Intermediate frequency output sintering, because the intermediate frequency output line is too small, the power has been lost in heat energy. 5. The harmonic current resistance of the current transformer burns out. 6. There is a problem with the inverter pulse transformer. 7. If the electric heating capacitor burns out, remove the copper bar and check it with a 1000V insulation resistance meter or a multimeter to see the charging and discharging. 8. The smelting furnace passes through the furnace and measures...
