G-type finned tube is a heat exchange element that improves heat transfer efficiency by adding fins to the surface of the heat exchange tube. G-type finned tube significantly improves heat transfer efficiency and reduces heat transfer resistance by increasing the outer surface area (or inner surface area) of the heat exchange tube, thereby enhancing the heat transfer effect.
Characteristics of G-type finned tube
High-efficiency heat transfer:
The heat transfer characteristics of G-type finned tube are related to the contact thermal resistance between its fins. The heat transfer characteristics of welding chips and sleeves are better, while the insertion and winding methods are worse. After re-crimping, the contact area is increased and the heat transfer characteristics are higher.
Corrosion resistance:
The bottom tube of G-type finned tube is protected by the wing to prevent atmospheric corrosion. Different types of finned tubes have different abilities to resist atmospheric corrosion.
Manufacturing process:
The embedded finned tube consists of a base tube and fins embedded in the base tube. The base tube is usually made of metal materials such as steel tube and copper tube, which has good thermal conductivity and pressure resistance. Fins can be made of metal materials such as aluminum and copper, and are embedded on the base tube through a specific process, which greatly increases the heat exchange area and improves the heat exchange efficiency.
Application fields of G-type finned tubes
G-type finned tubes are widely used in power engineering, metallurgical industry, cement industry, construction engineering, petrochemical industry and other fields. Its high efficiency heat transfer performance and energy-saving effect make G-type finned tubes perform well in these fields, which can significantly reduce the size of facilities and the consumption of metal materials, and improve the economy and reliability of operation.
Fins:
Mechanical bond (fin embedded in tube groove).
Maximum Tube Wall Operating Temperature: 400°C.
Type of Service: High temperature.
Manufacture
Fin strip is rolled in a uniform taper, helically wound into a plowed groove into the tube wall and simultaneously backfilled (by flat rotating discs) on both sides to lock the fin to the tube.
No tube material is removed. This gives an excellent bond with high pull out loads.
