The key points of selecting the corresponding fin tube for the heat sink of the cooling equipment

-
The heat medium (steam or hot water) of the heating system transfers heat to the room mainly by means of convective heat transfer (convective heat transfer is greater than radiant heat transfer) through the wall surface of the heat dissipation equipment. This kind of heat sink is generally called convection heat sink. The convection heat sink made of steel fin tube is generally called steel fin tube convection heat sink.
Laser welded composite fin tube manufacturer Murphy introduces the key points of fin tube selection:
1) the steel finned tube convection heat sink shall meet the requirements of heating system working pressure and system pressure, and shall meet the standards of China or the industry.
2) rigid heat sinks shall not be used in open heating systems and rooms with high ambient humidity (such as bathrooms and swimming pools).

 3) verify whether the standard heat dissipation per meter marked by the product sample is ≥ the industry standard in JG / T 3012.2-1998. According to the "standard heat dissipation test report per meter" and "pressure test report" issued by the manufacturer and tested by the recognized unit in China, check the test results and the data of product sample identification (it is required that the tested product is a sample, the test report within the past two years).
4)the manufacturer shall provide the water resistance characteristic data of steel fin tube convection heat sink.
5) check the appearance of steel fin tube convection heat sink. All welding parts shall be flat and smooth, and the processing surface at the interface shall be fine and ensure the perpendicularity and flatness. The surface coating shall be uniform and smooth, firmly adhered and free of bubbles.
 6) the applicable working pressure of the product is 1.0MPa for hot water heating medium and 0.3MPa for steam heating medium.
5) check whether the steel pipe used for heat sink is of good quality (seamless steel pipe or steel pipe for low-pressure fluid transmission), and whether the joint process between steel pipe and fin pipe is tight (for the joint using high-frequency welding process, JG / T 3012.2-1998 requires that the total actual weld length at the measurement point of each meter of fin pipe should be more than 85%, and the length of non continuous welding should not be more than 50 mm). The fin height shall be greater than 15mm.

Everything you should know about U bend tube

  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.
