DELLOK Carbon Steel Laser Welding Finned Tube Coil - 12 Million Meter Annual Capacity with Anti-Corrosion Protection

DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) specializes in high-performance carbon steel laser welding finned tubes designed for superior heat transfer efficiency and exceptional corrosion resistance.

Established in 2002 with 66 million yuan in fixed assets, our facility employs over 200 staff including 33 technical experts. We operate 47 finned tube production lines with an annual capacity exceeding 12 million meters, supported by comprehensive quality control systems throughout the entire production process.

• Advanced laser welding process ensuring 99%-100% complete weld coverage
• Superior heat transfer efficiency compared to HF welding and wrapped fin tubes
• Zero bubbles or gaps between fins and base tube
• Space-saving design with enhanced thermal performance
• Exceptional anti-corrosion properties for extended service life
• Robust structural integrity resistant to shock and thermal stress
• Available in straight, bent, or coiled configurations

Our laser welding process utilizes high-intensity laser beams to create precise metal-to-metal bonds without filler materials. The operation occurs within a protective atmosphere, ensuring weld purity and eliminating impurities for optimal performance.

• 100% metallurgical bond between fin and base tube
• Minimal thermal resistance for maximum heat exchange
• Enhanced durability against thermal expansion and contraction
• Energy-efficient operation with long service lifespan
• Cost-effective solution through reduced maintenance requirements

Our laser welded finned tubes feature complete fusion welding without filler materials, processed under protective atmosphere conditions to maintain weld seam purity and structural integrity.
