Helical finned tubes are a highly efficient heat transfer element with helical fins. Its heat transfer area is several times to dozens of times that of the light pipe, which can enhance heat transfer, reduce flow resistance, and reduce metal consumption, thereby improving the economy and operational reliability of heat exchange equipment. Spiral finned tubes have been widely used in various boilers. Spiral finned tubes can be manufactured by a variety of methods. The finned tubes used in boilers, pressure vessels and other heat exchange equipment mainly include the following manufacturing methods: high frequency resistance welding spiral finned tubes, brazing spiral finned tubes and Integral helical finned tube. The manufacturing method, performance evaluation index, application and advantages of integral spiral finned tube are introduced in detail.
