مقدمة

G fin tube, a specialized heat transfer element, is extensively used in industrial المبادلات الحرارية, condensers, and air coolers. The tube is manufactured with fins embedded in the grooves of the base tube, creating a strong mechanical bond that enhances thermal performance, corrosion resistance, and durability. In particular, G fin tubes find widespread applications in power plants, petrochemical industries, and air-cooled مبادل حراري systems due to their exceptional heat transfer efficiency and long-lasting performance.

ما هو أنبوب الزعنفة G?

A G fin tube is a heat transfer tube that is characterized by embedding the fin inside a pre-cut groove in the outer surface of the base tube. The fin is then inserted into the groove, and the groove is closed tightly to lock the fin onto the base tube. This process creates a strong metal-to-metal contact, ensuring maximum thermal conductivity and preventing the fin from loosening due to high temperatures or vibrations.

The fin material is commonly made of aluminum or copper due to their high thermal conductivity, while the base tube can be made of various materials such as carbon steel, stainless steel, copper, copper-nickel, and titanium, depending on the specific application requirements.

Manufacturing Process

• A continuous spiral groove is milled on the outer surface of the base tube.
• Fin strip (usually aluminum or copper) is inserted into the groove.
• The groove is mechanically closed and locked, creating a strong mechanical bond.
• The finished G fin tube is inspected for dimensional accuracy and adhesion strength.
• Compared to L-type or KL-type fin tubes, G fin tubes have higher mechanical strength and better heat transfer performance.
