H Type Finned Tubes are high-efficiency heat transfer components made from carbon steel or stainless steel tubes with welded fins using high-frequency welding technology. The base tube and fins are metallurgically bonded to ensure excellent heat transfer performance, corrosion resistance, and mechanical strength, making them ideal for industrial heat exchanger systems.
Fin Type: H-shaped double rectangular fins
Fin Height: 12–30 mm
Fin Thickness: 1.0–1.5 mm
Tube Outer Diameter: 25–63.5 mm
Tube Wall Thickness: 2.0–6.0 mm
Tube Length: Up to 12 meters (customized available)
Fin Material: Carbon steel, stainless steel, or alloy steel
Base Tube Material: ASTM A179, A192, A210, A213, A333, or equivalent
Superior Heat Transfer Efficiency: H-shaped fins increase the contact area, enhancing thermal exchange performance by up to 30% compared with spiral finned tubes.
High Welding Strength: The high-frequency welding process ensures a strong metallurgical bond between fins and base tube, preventing fin detachment under thermal cycling.
Excellent Corrosion Resistance: Available in stainless steel or alloy materials for long-term durability under corrosive or high-temperature environments.
High Mechanical Stability: The H-fin structure resists deformation and provides strong rigidity for applications under high-pressure or high-velocity air flow.
Customizable Designs: Tube and fin materials, sizes, and configurations can be tailored to meet specific project requirements.
From a professional manufacturer’s perspective, we focus on quality assurance and process control to address customer concerns such as straightness, tolerance accuracy, and welding consistency:
Strict Dimensional Control: Tube straightness tolerance within ±1.5 mm/m; fin pitch deviation ≤0.2 mm ensures consistent assembly.
Uniform Welding Quality: 100% high-frequency weld inspection ensures continuous and strong bonding between fins and tubes.
Material Traceability: Each tube batch is traceable with mill certificates and chemical analysis reports.
Enhanced Surface Treatment: Optional anti-corrosion coating or galvanization improves service life in harsh environments.
Efficient Production Capacity: Automated production lines enable quick turnaround and consistent quality.
