Function and efficiency of finned tube

-
Increasing the surface area or internal standard area of the heat exchange tube can also improve the heat exchange efficiency of the murphy finned tube.
Murphy finned tube is a kind of wear-resistant, new and efficient heat exchange material. It is an efficient and energy-saving heat exchange component in the process of use. The equipment mainly uses high-frequency power supply as the heat source, effectively heating the steel pipe and steel strip at the same time, so it will be welded together.
Murphy laser welded stainless steel fin tube has the advantages of high heat exchange efficiency and large heat dissipation area, long service life of the whole product and wide temperature range. The product is widely used in petrochemical industry, economizer, waste heat recovery, greenhouse, power station boiler, wood drying and other industrial fields.

The installation of stainless steel finned tube is simple and economical, which reduces the connection point, so that the equipment installation will become more economical and fast, and to a certain extent, it also reduces the probability of water leakage at the connection point. The product maintenance is simple, and after the installation, it is basically unnecessary to carry out maintenance.
The fin tube has high efficiency of use. In the process of manufacturing, the steel tube and the fin are effectively wound and welded in full contact. The heat dissipation area of the fin tube is more than 8 times of that of the smooth tube. The inner part of the product will be more smooth and the resistance of the internal water flow is relatively small.

  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

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

Spiral plate heat exchanger equipment can be broken down, mostly because of quality problems. Compared with the heat transfer surface of other heat exchangers, the heat transfer surface of this heat exchanger is quite thin, that is, 0.5mm, and the allowable high corrosion degree is 0.05mm/ year. The material of common spiral plate heat exchanger equipment usually USES alloy material (304 or 316), 304 is the low cost of austenitic stainless steel, has the ability to resist corrosion to a certain range of organic matter, but the ability to resist hydrochloric acid and sulfuric acid is weak. Spiral plate heat exchanger equipment can be broken down, but also because of its own maintenance problems. Spiral plate heat exchanger equipment is an important component of heat exchange technology in process industrial equipment. The resilient gasket that seals between the various helical fins is a vulnerable part and also an easily aged part under natural conditions. Its service life has an impo
