Finned tube radiator is a kind of heat exchanger widely used in gas and liquid heat exchangers. It can enhance heat transfer by adding fins to ordinary tubes. The base pipe can be made of steel pipe, stainless steel pipe, copper pipe, etc. Fins can also be made of steel strips, stainless steel strips, copper strips, aluminum strips, etc.

Finned tube radiator can be divided into winding type, tandem type, welding type and rolling type in fin structure.

At present, steel finned tube is widely used. It uses the pressure resistance of steel tube to compound on a special machine tool. The finned radiator manufactured with steel finned tube has the advantage of high cost performance that other types of finned tube radiators can not replace.
