Stainless Steel Crimped Finned Tube
Stainless Steel Crimped Finned Tube is a high-efficiency heat transfer component made of stainless steel, where a metal strip is mechanically crimped and spirally wound around a base tube to form tightly bonded fins. This process eliminates welding, ensuring excellent thermal conductivity and corrosion resistance.

Stainless Steel Crimped Finned Tube Manufacturing Process
-
Material Preparation:
- The base tube is typically made of high-strength low-carbon steel or stainless steel (e.g., 304, 316) for pressure resistance and structural stability.
- The fin material is a thin, high-quality steel strip that undergoes oil and rust removal pretreatment to ensure compatibility with subsequent processing.
-
Spiral Winding and Crimping:
- Specialized equipment wraps the steel strip around the base tube at a preset spacing (5–12mm) while applying high-frequency induction heating to fuse the contact surfaces, creating a seamless metallurgical bond.
- This crimped design ensures minimal contact resistance, enhancing heat transfer efficiency.
-
Quality Control:
- After welding, the tube undergoes a hydrostatic test (≥1.2MPa) and visual inspection to eliminate leakage risks and structural defects.
Stainless Steel Crimped Finned Tube Advantages
- Enhanced Heat Transfer: The crimped fins maintain minimal contact resistance, improving thermal conductivity efficiency.
- Corrosion Resistance: Stainless steel (e.g., 304, 316) forms a self-healing oxide layer, making it ideal for harsh environments like coastal areas or chemical plants.
- Structural Stability: The spiral design provides mechanical strength, withstanding heavy winds, ice buildup, and extreme temperatures with minimal deformation.
- Durability: The crimped fins are resistant to rust and corrosion, ensuring a long lifespan with minimal maintenance.

Stainless Steel Crimped Finned Tube Appearance Dimension Inspection
Stainless steel crimped finned tube 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.
Stainless Steel Crimped Finned Tube Bending
Bending of fin tubes is an important step in the production process of stainless steel crimped finned tubes. Bending is to bend the helical stainless steel crimped finned tubes 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.
