About Fin Tube

翅片管是一种热交换元件。为了提高热交换效率，通常通过在热交换管表面增加翅片来增大热交换管的表面积（或内表面积），从而达到提高热交换效率的目的。

性能要求

翅片管作为一种热交换元件，长期工作在高温烟气条件下，如锅炉热交换器中使用的翅片管环境恶劣，高温高压，处于腐蚀性大气中，这就要求翅片管具有较高的性能指标。
1) 防腐性能
2）、耐磨性（抗磨损）
3)， low contact resistance (lower contact resistance)
4) Higher Stability
5），抗灰尘能力

High frequency welding spiral fin

High frequency spiral fin tube is one of the most widely used spiral fin tube， and is widely used in power， metallurgy， cement industry waste heat recovery and petrochemical industry. The high frequency welding spiral finned tube is to heat the outer surface of the steel strip and steel pipe until the plastic state or melting by using the skin effect and proximity effect of high frequency current while the steel strip is winding the steel pipe， and weld under a certain pressure of the winding steel strip. This high frequency welding is actually a solid phase welding. It is more advanced than inlaying， brazing (or overall hot dip galvanizing) methods， both in terms of product quality (fin welding rate is high， up to 95%)， and productivity and automation.

ASTM A106 is a common seamless carbon steel pipe material， its main components are carbon and iron. It is a kind of high temperature and high pressure pipeline material， widely used in oil， natural gas， chemical industry， electric power， aviation， shipbuilding and other fields.

The main features of a106 pipeline are high temperature resistance， pressure resistance， corrosion resistance， wear resistance and so on. It has excellent high temperature resistance and can withstand high temperatures of up to 600 ° C， so it is very safe and reliable to use in high temperature and high pressure environments. a106 pipeline also has good corrosion resistance， can be used in acid， alkali， salt and other corrosive media for a long time.

There are two main manufacturing processes for a106 pipeline， one is cold drawing process and the other is hot rolling process. The cold drawing process is to heat the billet to a certain temperature， and then draw the billet into a pipeline through the drawing machine. Hot rolling process is to heat the billet to a certain temperature， and then roll the billet into a pipe through the rolling machine. Each of the two processes has advantages and disadvantages， and the specific choice of the process depends on the use environment and requirements.

Pipeline a106 is a very excellent pipeline material， with good high temperature resistance， pressure resistance， corrosion resistance and other properties， widely used in various fields. During use， it is necessary to pay attention to the installation， maintenance and maintenance of the pipeline to ensure its long-term stable operation.
