What is Spiral Wound Finned Tube or Crimped Fin Tube?
Crimped finned tube also known as cold-rolled finned tube,it is a heat transfer element commonly used in heat exchangers and coolers. It uses cold processing technology to tightly wrap the fins around the base tube, and spot welds the head to prevent the fins from falling off, thereby increasing the heat exchange area and optimizing the heat transfer path, improving the heat transfer efficiency.
Quality control for crimped finned tube
The quality of the crimped finned tube is assured by hydrostatic or pneumatic testing, eddy current testing and tensile testing to verify the mechanical bond between the inner tube and the outer fins.
Crimped finned tube surface treatment:
For caron steel tube and carbon steel strip, normally hot galvanizing after fining. The galvanized crimped finned tube highly increase the anti rust capacity.
Delivery condition:
The tube ends are square cut, free of burrs, dry and blown clean on the inside and varnished on the outside on both ends. Desiccant is also put into each package for continental shipping.

Difference Between High Frequency Welded Fin Tubes and Crimped Fin Tubes
High frequency welded fin tubes: The manufacturing process is complex, high frequency welding equipment is required, and the cost is high, but the welding is firm and not easy to loosen.
Crimped fin tubes: The manufacturing process is relatively simple, the production cycle is short, and the cost is low, but it is easy to loosen and requires regular maintenance.

High Frequency Welded Spiral Fin Tube Application
The spiral fin tube radiator for vegetable and flower greenhouse is an efficient and durable heating equipment, especially suitable for greenhouse cultivation in cold seasons.
During the breeding and brooding process, the high-frequency welded fin tube radiator improves the heat exchange efficiency by increasing the heat dissipation area, and can raise the temperature in the brooding house to the required level in a short time. This design enables the farm to quickly reach and maintain a suitable temperature range (15-20 degrees Celsius) when heating in winter.
Hot-dip galvanized spiral wound fin tube for greenhouse heating, as a key component of the heating system, can efficiently and evenly transfer heat to keep the temperature in the greenhouse within a suitable range
As a high-efficiency heat exchange element in modern industrial and civil heating systems, the unique design of the helical tension wound finned tube radiator for steam heating not only significantly improves the heat transfer efficiency, but also optimizes the space utilization rate, becoming an indispensable thermal energy source in many fields. equipment.
The working principle of the crimped fin tube is based on the principles of heat conduction and convection. When the hot water or steam of the heating system flows through the finned tube, the heat is quickly transferred to the heat sink through the fins and then dissipated into the air. This design makes the heat exchange more efficient and is particularly suitable for workshop environments that require a lot of heat dissipation.
