Welcome to Murphyfinnedtubes!

 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-temperatur...

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 tu...

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 ...

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...

In this video we will introduce the mainstream high frequency finned tubes currently on the market. We will show you around our factory, our finned tube prodution line.

The  high-frequency induction welding  process is currently a commonly used welding process in the field of pipelines. Its high efficiency and environmental protection characteristics have attracted the favor of many pipe welding producers and have been widely used. In practical applications, high-frequency straight-seam induction welding was originally applied to the welding of ordinary carbon steel, that is, the welding application of ordinary materials. With the maturity of high-frequency induction welding technology and the technological advancement of high-frequency welding machine power supply, the current high-frequency straight-seam induction welding technology has been applied to the welding of some special materials, including aluminum alloy, copper, stainless steel and other metals The pipeline welding of materials provides pipeline manufacturers with a new way to manufacture products and innovates the traditional production technology of some products. Princip...

A heat exchanger is an energy-saving device that realizes heat transfer between materials between two or more fluids at different temperatures. It is to transfer heat from a fluid with a higher temperature to a fluid with a lower temperature so that the fluid temperature reaches the process. The specified index meets the needs of process conditions and is also one of the main equipment to improve energy efficiency. The heat exchanger industry involves nearly 30 kinds of industries such as HVAC, pressure vessels, water treatment equipment, chemical industry, petroleum, etc., forming an industrial chain with each other. Data show that the market size of China’s heat exchanger industry in 2010 was about 50 billion yuan, mainly concentrated in the fields of petroleum, chemical industry, metallurgy, electricity, shipping, central heating, refrigeration, and air conditioning, machinery, food, pharmaceuticals, and other fields. Among them, the petrochemical industry is still the largest ...

In the marine turbine, the  heat exchanger  is to ensure that the turbine is in normal equipment. Of course, there are many common heat exchangers, such as runner type and plate type. The advantages and disadvantages of different heat exchangers are very obvious. The plate type heat exchanger is often used in the electrical equipment of the turbine engineering. This type of heat exchanger is small in size and relatively high in efficiency. It has been used in marine turbines, but it is in urgent need of further promotion. Based on the current situation, the actual application of the plate heat exchanger is introduced in detail. In the marine turbine, heat exchange is undoubtedly a very critical factor to ensure the normal use of the turbine. When the turbine is working, it needs to maintain a certain temperature to ensure the normal operation of the machinery. At present, there are many heat exchangers in the marine turbine. Among them, the plate type is a very important one...

Spiral  plate heat exchanger  is made of two parallel metal plates made of two spiral channels, heat exchanger between the hot and cold fluid through the spiral plate wall, especially in the treatment of slurry containing particles or fibers in suspension Materials or various viscous fluids. The two most important links in the production process of spiral plate heat exchangers are plate rolling and fixed-length column welding. Murphy has a fully automatic spiral plate flexible production line. The welding of coiled plates and fixed-length columns is performed by CNC operations. The studs are welded with studs, and the welding current is automatically controlled to ensure that the studs are firmly welded, free of overburning and under-welding defects. The fixed-distance columns have high welding efficiency and accurate positioning; the plate rolling force is automatically controlled to ensure The spiral body after rolling has the best tightness, so that the positioning colum...
