Spiral finned tube is a highly efficient heat transfer element with spiral fins for power plant Boilers. Its heat transfer area is several to several tens of times that of a bare pipe, which can Enhance heat transfer, reduce flow resistance, and reduce metal consumption, thereby Improving the economy and operational reliability of heat exchange equipment. At present, Spiral finned tubes have been widely used in various industrial boilers. Other tubes such as Finned tubes, H type finned tubes is also provided.
