Ürün Tanımı

H Type Finned Tubes Welded Finned Pipes Tubes For Heat Exchanger 0

H Type Finned Tubes Welded Finned Pipes Tubes For Heat Exchanger

Material Introduction

H-type finned tubes are high-efficiency heat transfer elements consisting of carbon steel or alloy steel base tubes with H-shaped fins welded on both sides. These tubes are primarily used in industrial heat exchangers, economizers, and air preheaters for power plants, refineries, and boilers. The H-shaped fin design maximizes heat exchange surface area, reduces air resistance, and enhances overall thermal efficiency.

Specifications

Tube Material: Carbon steel, alloy steel, stainless steel
Fin Material: Carbon steel, alloy steel
Tube Outer Diameter: 25 mm – 63.5 mm
Fin Height: 12.5 mm – 25 mm
Fin Thickness: 1.0 mm – 1.5 mm
Fin Pitch: 3.2 mm – 10 mm
Fin Type: H-type double rectangular welded fins
Tube Length: Up to 12 meters (customizable)

Main Features

Enhanced Heat Transfer Efficiency: The H-shaped fins form a continuous and wide heat transfer surface, increasing the heat exchange rate by over 30% compared to spiral fin tubes.
Excellent Structural Strength: Welded fins ensure superior mechanical bonding and durability under high temperature and pressure conditions.
Low Air Flow Resistance: The parallel fin arrangement creates smooth airflow channels, effectively reducing dust accumulation and pressure drop.
Corrosion and Oxidation Resistance: Available in various grades of carbon steel or alloy steel, suitable for harsh service environments.
Easy Maintenance: The rectangular fin structure facilitates cleaning and inspection, improving system reliability and service life.

Our Advantages

From a professional manufacturing perspective, customers typically care about heat transfer efficiency, welding quality, dimensional tolerance, and operational reliability.
We address these concerns as follows:

Precision Welding: Using high-frequency resistance welding ensures uniform fin attachment, minimizing thermal stress and improving bonding strength.
Dimensional Accuracy: Fin height tolerance within ±0.2 mm and tube straightness within 1 mm/m guarantee easy assembly and stable performance.
Material Traceability: All tubes and fins are sourced from certified mills with full inspection reports, including tensile, impact, and hardness tests.
Thermal Performance Optimization: Custom fin pitch and height configurations available for specific gas flow and heat transfer requirements.
