Product Features
Spiral coil design, enhancing heat transfer efficiency
The spiral wound stainless steel pipe adopts a spiral forming structure, which increases the contact area between the fluid and the pipe wall, and enhances the internal turbulence. This design enables the pipeline to achieve efficient heat exchange performance in compact thermal management equipment.
Reliable corrosion resistance suitable for industrial media
This product is made of high-grade stainless steel and can fully resist moisture, coolant, weak acids, and other common industrial media. It is suitable for long-term use in refrigeration, chemical processing, food production, and pharmaceutical industries.
Wide temperature applicability
It can operate normally in both low-temperature cooling conditions and high-temperature heat exchange systems. It is widely used in condenser units, liquid cooling devices, and various thermal management systems' condenser installations that require stable temperature control.
Reinforced structure for continuous operation
Compared to straight pipes, the spiral-wound structure has better mechanical strength and vibration resistance, making it suitable for equipment that requires long-term continuous operation.
Stable performance and long service life
Strict material selection and precise forming ensure the stability of quality. This pipe can maintain stable heat transfer efficiency during use, reducing maintenance frequency and operating costs.
Flexible custom manufacturing service
We can produce according to drawings or technical specifications, covering aspects such as diameter, wall thickness, spiral size, connection type, and material grade, to meet different installation and usage requirements.
Application Fields
Compact refrigeration and condenser equipment
The DN25 specification, combined with the spiral winding structure, makes it particularly suitable for installation in compact refrigeration devices and condenser components with limited space. It is commonly used in water chillers, cooling modules, and integrated thermal management system condenser equipment that require efficient heat dissipation.
Precise thermal control technology in chemical production systems
On chemical production lines, the stability of temperature directly affects reaction efficiency. The spiral-wound pipes have reliable heat exchange performance. They can adapt to continuous operation, pressure conditions, and corrosive medium environments, and are suitable for use in industrial heat transfer systems.
Hygienic cooling and heating systems for food machinery
The stainless steel structure of the product allows the pipes to be used in food-grade environments that require cleaning and stable temperature control. It is typically installed in cooling channels, heating circulation systems, and processing lines, where durability and hygiene are required.
Pharmaceutical equipment with strict temperature requirements
Many pharmaceutical processes require long-term stable cooling or condensation. Spiral-wound stainless steel pipes are suitable for production equipment, reactors, and temperature regulation systems that require reliability and consistency in control.
Liquid cooling and high-density heat dissipation devices
The spiral-wound design increases the heat transfer area, making it suitable for use in liquid cooling units, server cooling modules, and other high-load thermal management devices that must maintain stable operating temperatures.
Customized heat exchange systems and OEM equipment manufacturing
This type of pipe is also often used in non-standard heat exchangers and special cooling structures. We can customize it for different diameters, spiral sizes, material grades, and connection methods to adapt to different equipment layouts and operating requirements.
Customized Purchasing Advice
1. Before placing an order, please confirm the working conditions. Clearly define whether the pipeline is for cooling, condensation, or heat exchange, and also confirm the working temperature, pressure, and fluid type. Different working conditions may require different materials and structural strength.
2. Provide basic dimensions and installation requirements. To ensure the accuracy of production, customers need to provide key parameters such as outer diameter, wall thickness, coil diameter, total length, and quantity. For helical structures, it is recommended to provide installation drawings.
3. Select the appropriate material grade. 304 stainless steel is suitable for general environments, while 316/316L is more suitable for corrosive media or situations requiring higher stability, especially in chemical, pharmaceutical, and condenser equipment of thermal management systems.
4. Select the appropriate surface treatment method. For most industrial systems, standard acid washing and passivation treatment are applicable. For food processing, pharmaceutical, or clean cooling equipment, polishing or more advanced surface treatment processes would be better.
5. We support customized production of spiral wound stainless steel pipes.
Our customization services include dimensions, helix diameter, material, and connection type. DN25 spirally wound stainless steel pipes can be produced according to the drawings to fit refrigeration equipment, heat exchangers, condensers, and other non-standard thermal management equipment.
Specification Selection Guide
Select Pipe Size Based on Cooling Capacity
When choosing the specifications, the required cooling or condensation capacity should be considered first. Systems with higher flow demands often require a larger pipe diameter, which can reduce resistance and maintain stable heat transfer efficiency.
Consider Pressure and Structural Strength
For equipment operating under high pressure or subjected to long-term continuous load, it is recommended to use a thicker pipe wall to ensure mechanical strength and safe operation, especially in applications such as condensers in refrigeration and thermal management systems.
Match the Helix Diameter to the Equipment Space
Choose the winding diameter of the helix according to the internal installation space of the heat exchanger or cooling device. An appropriate coil diameter helps improve heat exchange performance and makes the structure more compact.
Check the Compatibility of Connection Dimensions
The pipe diameter and interface type should be compatible with the connections of the condenser, pump, or heat exchanger to avoid problems such as leakage, vibration, or installation difficulties during operation.
