Specification

Category	Parameter	Specification Range	Remarks
Base Tube	Material	Carbon Steel (ASTM A179/A192), Stainless Steel (304/316L), Alloy Steel (T11/T22), Copper, Nickel Alloys	Selection depends on corrosion/thermal requirements.
	Outer Diameter (OD)	15mm–50mm (Common: 25mm, 38mm)	Customizable.
	Wall Thickness	1.5mm–4mm	Higher pressure requires thicker walls.
	Length	≤12 meters (standard)	Longer lengths possible but constrained by transport.
Fins	Material	Same as base tube or compatible (e.g., aluminum fins for carbon steel tubes).	Aluminum fins for low-temperature applications (<150°C).
	Fin Height	8mm–20mm	Higher fins = larger surface area but increased airflow resistance.
	Fin Thickness	0.3mm–1.2mm	Thicker fins improve durability but reduce heat transfer efficiency.
	Fin Spacing (Pitch)	3mm–12mm	Closer spacing for high heat transfer; wider spacing for dusty environments.
	Attachment Method	Spiral-wound (L/LL footed) or Welded (HFW)	Welded fins offer better bond strength for high-temperature applications.
Performance	Heat Transfer Area Ratio	5x–15x bare tube area	Depends on fin density/height.
	Temperature Range	Carbon Steel: -20°C–400°C; Stainless Steel: -200°C–650°C; Aluminum: ≤150°C	Material limits apply.
	Pressure Resistance	≤6MPa (depends on base tube)	Complies with ASME/EN/JIS standards.
	Surface Treatment	Galvanized, Painted, Aluminized	Anti-corrosion or high-temperature oxidation protection.
Standards	Manufacturing Standards	ASTM B111 (Copper), EN 10204, JB/T 6512	Certifications available (e.g., ISO 9001).
	Tolerances	Fin Height: ±0.3mm; Fin Spacing: ±1mm per 10 fins	Critical for consistent performance.
Applications	Typical Uses	Boilers, Heat Exchangers, Waste Heat Recovery, HVAC Condensers/Evaporators	Suitable for air/gas/steam/oil fluids.
Customization	Options	U-bends, Flanged Connections, Anti-fouling Designs (e.g., wider spacing for dust)	Tailored to system requirements.
