How to maintain finned tubes

-
Take good care and maintenance can extend the use, laser welded finned tube coil is the same, so what are the specific aspects of finned tube maintenance? Let's take a look at the introduction given by the Murphy expert of laser welded composite fin tube.
 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 according to the number sequence on the fins, which should be corrected.
Murphy experts suggest regularly check whether the cleaning of each finned tube is perfect, whether there are depositions, coking, rust layer and other scaling adhesion, and clean 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 is in good condition, so as to avoid leakage caused by rubber washer degumming and damage.

The plate heat exchanger pressing nuts and upper and lower guide rods shall be lubricated with lubricating grease frequently.
All instruments shall be regulated by specially assigned person, operation and maintenance shall be carried out in strict accordance with operating procedures.
When the rubber gasket needs to be replaced or the degummed part needs to be repaired, the finned tube shall be removed and placed on the table, remove the old gasket, or wiped out the glue traces in the groove of the finned tube by fine sandpaper at the degumming place, then wiped out the oil traces in the groove with carbon tetrachloride or trichloroethylene, and then the back of the new rubber gasket shall be wiped out with fine sandpaper, similarly with carbon tetrachloride or trichloroethylene The solvent wiped out the oil. Then, apply a thin layer of glue on the back of the groove and rubber washer, and let it dry a little bit, so as not to stick fingers, but it still sticks. That is to say, the rubber washer is embedded in the groove, the four sides are flattened, a layer of talcum powder is applied, and then the finned tube is installed on the equipment rack and clamped gently. The glue can be put into operation after a period of time according to the instructions.

  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...

  A heat exchanger is a device designed to transfer heat between two or more fluids with different temperatures (ie liquid, vapor or gas). Depending on the type of heat exchanger used, the heat transfer process can be gas-to-gas, liquid-to-gas or liquid-to-liquid and takes place through a solid separator that prevents fluid mixing or direct fluid contact. Other design features, including building materials and components, heat transfer mechanisms, and flow configuration, also help to classify the types of heat exchangers available. After discovering applications in a wide range of industries, we designed and manufactured a variety of heat exchange equipment used in heating and cooling processes. This article focuses on heat exchangers, exploring various available designs and types, and explaining their respective functions and mechanisms. In addition, this article outlines the selection considerations and common applications of each type of heat exchange equipment. Heat Exchanger t...

How to Optimize the Design of Finned Tube Phase Change Heat Storage

  Finned tube structure 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 transfer 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.   Finned tube material The finned tube has a wide range of materials, including stainless steel, carbon steel, titanium and copper alloys, etc. The corrosion resistance of the industry has greatly increased.
