Welcome to Murphyfinnedtubes!

High-frequency welding finned tube is one of the most widely used spiral finned tubes. It is now widely used in the waste heat recovery of power, metallurgy, cement industry and petrochemical industry. How does high   frequency welding finned tube  work? The high-frequency welding finned tube   use the skin effect and proximity effect of the high-frequency current to heat the outer surface of the steel strip and the steel tube while the steel strip is wound around the steel pipe, until the plastic state or melting, a certain pressure on the wound steel strip Complete welding next. This high-frequency welding is actually a solid-phase welding. Compared with inlaying, brazing (or integral hot-dip galvanizing) and other methods, it is excellent in terms of product quality (high welding rate of fins, up to 95%), productivity and degree of automation. High-frequency welding uses solid resistance heat as energy source. The resistance heat generated by the high-freq...

1. Metal material heat exchanger Common materials are carbon steel, alloy steel, copper and copper alloy, aluminum and aluminum alloy, titanium and titanium alloy. Because the thermal conductivity of metal material is large, the heat transfer efficiency of this kind of heat exchanger is high. 2. Non-metallic material heat exchanger Commonly used materials are graphite, glass, plastic, ceramics, etc. Because of the small thermal conductivity of nonmetallic materials, the heat transfer efficiency of this type of heat exchanger is low. Often used in corrosive systems. hashtag www.murphyfinnedtubes.com 1. Tube heat exchanger A heat exchanger that conducts heat through a tube wall. It can be divided into shell heat exchanger, coil heat exchanger, tube heat exchanger, fin heat exchanger and so on. 2. Plate heat exchanger A heat exchanger that conducts heat through a plate surface. According to the structural form of heat transfer plate can be divided into plate type, spiral plate ...

The long-term use of any item can not be separated from the care and maintenance. Murphy laser welding fin tube is no exception. So what are the specific aspects of fin tube maintenance? Generally, when water is used for circulation at the beginning of operation, there may be slight leakage. When the temperature rises to the sterilization temperature, the leakage will disappear by itself. If the leakage does not stop, the finned tube must be compressed a little more. If it is still ineffective, it is necessary to open and check the rubber gasket. It is also possible that the finned tubes are arranged in the order of numbers on the fins, which should be corrected. Regularly check whether the finned tubes are complete, whether there are deposits, coking, rust layer and other scaling adhesion, and clean them immediately. At the same time, it is also necessary to check whether the adhesion between each fin tube and the rubber washer is tight, and whether the rubber washer itself ...

Compared with other technologies, laser-welded stainless steel finned tube can greatly save material cost and achieve high penetration rate, effectively prevent the corrosion of its gap during use, thus effectively extend the service life of its equipment to a certain extent, and reduce the thermal resistance of its heat transfer. In terms of quality control of laser-welded stainless steel finned tube, its equipment mainly adopts its CCD monitoring system in the production process, monitors the welding area in the whole process, approves the first piece, USES the metallographic analysis system, obtains the welding status, and ensures the product quality qualified before continuous production. www.murphyfinnedtubes.com Laser-welded stainless steel finned tubes are widely used in chemical engineering, power engineering, air conditioning engineering, petrochemical engineering and refrigeration engineering, such as surface air cooler, air heater, fan coil used in air conditioning engi...

Finned tube is a common heat exchange component in our heat exchangers. In these finned tubes, the functions of finned tube in each category are different, the differences are as follows: Single metal composite finned tube is made of aluminum tube rolled as a whole, called aluminum rolled finned tube, no contact thermal resistance, high strength, heat resistance and mechanical vibration, good thermal expansion performance, and has considerable expansion heat transfer surface. This kind of fin tube heat exchanger, the effect is preferred to the series or wrap heat exchanger, is a very wide use of heat exchanger. The single metal composite finned tube can also be directly rolled by steel tube or copper tube. The difference between bimetallic finned tube and single metallic finned tube technology center home page straight  straight  double metal finned tube and single metal finned tube, the difference between finned tube is a common heat exchange component in our heat exchanger...

Spiral plate heat exchanger improved heat transfer, actually also is in order to improve the efficiency of the spiral plate heat exchanger and the ability to, first of all, we actually is to pay attention to, and also reduce the thickness of the plate thickness plate design, and on its corrosion resistance would have no relation, is associated with the bearing capacity of spiral plate heat exchanger equipment. If the plate is thickened, the pressure capacity of the heat exchanger can be improved. , spiral plate heat exchanger on the plate if using combination of chevron plate, this time also is to pay attention to each other with respect to its adjacent plate upside down, on the corrugated will have to contact each other, at this point, we also is to pay attention to, actually this time also can form high density, homogeneous distribution of fulcrum, plate Angle away L and its edge sealing structure has gradually improve, make the heat exchanger equipment has the very good bearing cap...

Today Murphy experts will share some basic knowledge of heat exchanger. 1. Definition of heat exchanger The heat exchanger is a heat exchange device that transfers part of the heat of the hot fluid to the cold fluid, so that the temperature of the fluid reaches the index specified in the process flow. 2. Function The main function is to ensure the specific temperature required by the process for the medium, and also to improve energy utilization, recover waste heat, waste heat and low-level heat energy. 3. Application The heat exchanger has a wide range of applications. It is general-purpose equipment widely used in industries such as chemical industry, oil refining, power, atomic energy, light industry, food pharmacy and machinery manufacturing. The heat exchanger can be a separate device, such as a heater, a cooler, and a condenser; it can also be a component of certain process equipment, such as a heat exchanger in an ammonia synthesis tower.       ...

Finned tube heat exchanger is one of the earliest and most successful discoveries in the process of improving tube heat transfer. Up to now, this method is still the most widely used of all kinds of tube heat exchange surface enhanced heat transfer methods. It is not only suitable for single finned tube heat exchangers and is widely used in power, chemical, petrochemical, air-conditioning and refrigeration engineering. Finned tube heat exchangers are widely used in power, chemical, petrochemical, air-conditioning and refrigeration projects, such as surface-type air coolers, air heaters, and fan coils used in air-conditioning projects. Refrigerator evaporators and frost-free refrigerator evaporators used in refrigeration projects are not only suitable for the flow of single-phase fluids, but also have great value for phase change heat. At present, most of the finned tube heat exchangers for clean gas use a new and efficient fin surface structure, which has achieved a significant en...

Known as the boiler, it is most of the time we  use, the boiler with finned tube is mainly used for heat transfer, so whether the boiler finned tube fin, the more the better, the answer is no. When the heat transfer area of finned tube used in our boiler is doubled, the heat transfer coefficient cannot be doubled, but a discount, usually (0.9-- 0.7), and the higher the fin, the greater the discount value, even reduced to (0.5) below. After the appeal, we can know that the higher the fin, the lower the use efficiency will be, so the production cost of finned tube for each boiler is increased, but its use effect is not increased, so it is not cost-effective. https://szmurphy.en.alibaba.com/product/62416452056-811592052/Murphy_Aluminum_boiler_laser_welding_heat_exchanger_Laser_Welded_Finned_Tubes_heat_exchange_for_Solar_Water_Heating.html?spm=a2700.icbuShop.89.9.118b4a24IC9Riu Murphy heat technology laser welded stainless steel finned tube design is mainly to improve the he...
