Welcome to Murphyfinnedtubes!

Finned tube is a kind of heat exchange element, which is often used in high temperature and flue gas space. In daily life, such as boilers, finned tubes need to be used for heat exchange execution. In such a harsh environment During daily operations, the finned tube itself is required to have corrosion resistance and stability. The finned tube is a typical heat exchange element, in order to improve the heat exchange efficiency, usually by adding fins on the surface of the heat exchange tube to increase the outer surface area of ​​the heat exchange tube, so as to improve the heat exchange For the purpose of efficiency, such a heat exchange tube. Finned tubes work under high-temperature flue gas conditions for a long time. For example, finned tubes for boiler heat exchangers are used in harsh environments, high temperature and high pressure and in corrosive atmosphere, which requires finned tubes to have high performance indicators. For example, excellent corrosion resistance. Many tim

 Heat transfer oil radiator (to reduce the heat generated by equipment operation) is a relatively common equipment in the industry in recent years, but we also know that some large industrial equipment will have some unsafe factors in use, which will cause us to Degree of damage. The air heater is an electric heating device that mainly heats the gas flow. The heating element of the air heater is a stainless steel electric heating tube, and the inner cavity of the heater is equipped with multiple baffles (baffles) to guide the gas flow direction and extend the residence time of the gas in the inner cavity, so that the gas is fully heated and the gas Heating evenly and improving heat exchange efficiency. The heating element of the air heater is stainless steel heating tube, which is made of seamless steel pipe with electric heating wire, and the gap is filled with magnesium oxide powder with good thermal conductivity and insulation. When the current passes through the high-temperature re

The problem of tube oxygen corrosion in  finned tube heat exchanger s has always been a key problem to be solved in the industry. If we can solve the problem of finned tube corrosion in oxygen-containing medium, it will play a positive role in the development of the existing technology. In the long-term production practice, Murphy also summarized some methods to solve the problem of internal corrosion of the fin tube. When designing the heating system of the finned tube heat exchanger, it is necessary to avoid mutual circulation with oxygen as much as possible and to seal as much as possible. When replenishing water to the fin tube, it should be deoxidized. When the finned tube heat exchanger stops heating, it should be fully maintained with a drying method or deoxygenated water. Also, when testing the pressure of the newly installed finned tube heat exchanger, whether it is hydraulic testing or adding solvents, non-toxic rust inhibitors should be used. During use, if the finned tube h

Finned tubes  are widely used in power, chemical and other industries. Many spiral heat transfer surfaces or threaded tubes can be regarded as finned tubes. It has a significant effect on expanding the heat exchange area and promoting turbulence, and it has a great effect on both single-phase-convection heat transfer and phase-change convective heat transfer. The structure of the finned tube heat exchanger is basically the same as the general shell and tube heat exchanger. Just use finned tubes instead of light tubes as the heat transfer surface. Finned tube heat exchangers are also often used to heat or cool the gas outside the tube, and steam or water is passed through the tube, such as air coolers, boiler economizers, radiators, etc. The finned tube has a wide range of materials, including stainless steel, carbon steel, titanium-copper alloy, etc. The corrosion resistance of the industry has greatly increased. Laser welding spiral fin tube is a new, wear-resistant and efficient heat

In the petrochemical industry, the application of Murphy heat exchangers are indispensable. High-efficiency #plateheatexchangers : can better deal with higher pressure and temperature. Specifically, the welded plate heat exchanger has strong convenience, small size, light weight, good heat transfer performance and low price. Therefore, it has been better used in the petroleum production process. The high-efficiency plate heat exchanger can cool mechanical lubricating oil and fresh water, can cool oil field related intermediate products, and can also heat crude oil. #Spiralheatexchanger: This is a modern and efficient heat exchanger equipment, widely used in many countries and the petrochemical industry in the region. Compared with traditional heat exchangers, spiral plate heat exchangers have many advantages, mainly including: high heat transfer coefficient, self-washing and anti-deposition, etc. Spiral baffle heat exchangers have achieved very good application effects in the petrochem
