Applications of Laser Welded Finned Tubes of Murphy Thermal Energy

-
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 enhanced heat transfer effect.

Murphy Thermal (Suzhou) Co., Ltd. has been focusing on the development and research of laser welding finned tubes. Compared with other processes, it has greatly saved material costs, achieved high penetration rate, can prevent gap corrosion, prolong service life, and reduce heat transfer Thermal resistance, now it has been applied in various fields such as boilers, chemicals, ships, waste heat power generation, and home improvement. In the boiler industry, the heat exchange area is larger, and it is environmentally friendly, energy efficient, and meets national emission requirements. The advantages of integrated finned tubes have been fully utilized.
In terms of quality control:
1. Using of the CCD monitoring system in the production process, monitoring the welding area throughout.
2. The first article is approved, and a metallographic analysis system is used to obtain the welding status to ensure continuous production after the product quality is qualified.
3. Using of high-quality, high-standard materials, starting from the source to ensure that the product quality is qualified.
4: Break through the material limitation and use different materials for processing.
5: Easy for re-processing, can be directly coiled and bent.
6: The welding heat-affected zone is small, and the metallographic changes are small, making small-diameter finned tube processing possible.
7: The thickness of the base pipe can be 0.8-1.5 mm, and the thickness of the fins can be 0.3-1 mm. Compared with other processes, the material cost is greatly saved.

  Murphy can make  U bend tube  in our factory according to customer requirements. The elbow is heat treated according to the customer’s requirements, and then hydrostatic pressure test and dye penetration test are performed as needed. U-shaped elbows are widely used in  heat exchanger  systems. Heat exchanger equipment based on stainless steel U bend tube plays an important role in the nuclear industry and petrochemical machinery manufacturing. U bend tube heat exchangers are specially designed for high temperature applications, especially steam condensing or hot oil systems. When the differential expansion makes the fixed tube-sheet heat exchanger unsuitable, and in some cases the floating head type (HPF) cannot be selected, the U bend tube heat exchanger will be selected. The surface of the finished U-shaped elbow should be free from scale and scratches after bending. Dimensional tolerance U-bend pipes are in accordance with relevant regulations of TEMA R.C.B. and ASTM A566 and ASTM

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

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
