G type fin tube, also known as embedded finned tube, where g means slotted. It is formed by screwing fin strips made of copper or aluminum into machined grooves and backfilling to secure the lock. Fill the base tube material. Compared with other finned tubes, G type fin tubes are firmer. Therefore, it is widely used in places where high-temperature heat transfer is required. The G type fin tube is a circumferential finned tube in which the fin is mechanically embedded in the groove, the groove is plowed into the tube, and the roller is locked in place, thereby forcing the groove to tightly surround the fin base.

Advantages of G Fin Tube

1.High production efficiency, continuous winding production;

2.Low cost. It relies on the characteristics of high-frequency welding itself-skin effect to heat the surface of the workpiece to achieve the purpose of welding firmly, without adding any filler metal material during the welding process;

3.Since the high-frequency current only passes through the shallow surface of the steel pipe, the welding heat-affected zone is small, so the additional wall thickness caused by this need not be considered in the design calculation; the workpiece does not need to be heat treated after welding;

4.The welding is reliable, can withstand the thermal shock fluctuation caused by frequent opening and shutdown.
