Structure and manufacturing technology of laser welded stainless steel finned tube

-
Stainless steel finned tube can be divided into two basic types: longitudinal type and radial type. Other types are the development and deformation of these two types. For example, the shape of large helix angle finned tube is close to the longitudinal, and the shape of small helix angle finned tube is close to the radial fin has circular, rectangular and needle shape.

Laser welded stainless steel finned tube can be set outside the tube, called outer finned tube, or inside the tube, called inner finned tube or both. Products can be classified into integral finned tube, welded finned tube, high-frequency welded finned tube and mechanically connected finned tube according to their manufacturing process.
The laser welded composite fin tube is manufactured by brazing or inert gas welding. Murphy uses modern welding technology can make the fins of different materials connected together, and can effectively make the fin tube simple, economic, with better heat transfer and mechanical properties, which has been widely used.

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.
