What is a fin tube coil?
Finned tube coils are heat exchange elements formed by bending finned tubes through coiling machines and other equipment to form a specific shape. Its core feature is to increase the heat exchange efficiency by increasing the surface area, while optimizing the structure to meet the needs of specific working conditions.
Structural features of fin tube coils
Finned tube coils consist of a base tube and fins welded on the surface. Through the coiling process, spiral and double-layer structures are formed to reduce fluid resistance while ensuring heat exchange efficiency. This structure can effectively increase the heat transfer area, especially in high temperature, high pressure and corrosive environments.
Application scenarios of finned tube coils
It is mainly used in air conditioning and refrigeration, automobile cooling, petrochemicals, electric power and other fields. For example, air conditioning condensers and evaporators use finned tube coils to achieve heat exchange, while automobile radiators use their optimized structures to ensure the normal operating temperature of the engine.
What is a laser welded finned tube coil?
Laser welded finned tube coil is a heat exchange element that tightly connects the fins to the base tube through laser welding technology, and is commonly used in industrial heat exchange systems. Its structure uses a laser beam to fix the fins on the surface of the base tube to form an efficient heat dissipation structure.
Structural features of laser welded finned tube coil
Laser welded finned tube coil consists of a base tube and fins. The base tube is usually made of metal materials such as stainless steel and carbon steel. The fins are firmly attached to the surface of the base tube through laser welding technology, and the heat transfer efficiency is improved by increasing the heat exchange area.
Application scenarios of laser welded finned tube coil
It is mainly used in chemical industry, power, refrigeration, oil and gas mining and other fields, especially in industrial scenarios that require high heat exchange efficiency, such as boilers, heat exchangers and other equipment.
Advantages of laser welded fin tube coil technology
High-efficiency heat exchange: Laser welding ensures that the fins are tightly combined with the base tube, reducing thermal resistance, and the heat exchange efficiency is 20%-30% higher than that of traditional fin tubes;
Various materials: Supports a variety of material combinations such as stainless steel, carbon steel, and copper to meet the needs of different working conditions;
Strong corrosion resistance: Surface treatment technology can improve corrosion resistance and extend service life.

Finned tube coils Appearance Dimension Inspection
Finned tube coils appearance dimension inspection is one of the important links to ensure the quality and performance of fin tubes.
The inspection items mainly include fin height, fin spacing, fin thickness, base tube wall thickness and outer diameter, etc.
Datang Finned tube coils Bending Processing
Bending of fin tubes is an important step in the production process of finned tube coils. Bending is to bend the finned tube coils material through specific mechanical equipment to form a suitable curvature to meet different usage requirements.
This step requires strict control of the bending angle and curvature to ensure the fit between the fin and the base tube and the heat dissipation effect.
Finned tube coils Pull Off Test
Finned tube coils pull-off test is a test used to detect whether the fin tube will fall off when subjected to tension, mainly used to ensure the quality and reliability of the fin tube.
Datang’s this test is very important in the production process because the finned tube coils will be subjected to various stresses during operation, such as temperature changes and pipe expansion, which may cause the fin to fall off, thereby affecting the performance and safety of the heat exchanger .
