ASME Standard Serrated Spiral Boiler Fin Tube with 1 Year Warranty and 5 Years Core Components Warranty for Natural Circulation Heat Exchange

The serrated spiral finned tube is an advanced extended surface design developed from standard spiral finned tubes. Using similar manufacturing processes to high-frequency welded spiral finned tubes, this variant features pre-cut strip gaps that naturally separate during winding to create a distinctive gear-shaped profile.

This innovative design offers superior performance characteristics including tight bonding, high strength, excellent thermal shock resistance, and enhanced heat transfer efficiency. The serrated configuration disrupts flow boundary layers to intensify heat exchange while maintaining minimal flow resistance and strong corrosion resistance.

• Significantly increased heat transfer surface area compared to bare tubes
• Optimized thermal performance with reduced material consumption
• Available in multiple manufacturing methods including high-frequency resistance welding, brazing, and integral spiral construction
• Maintains structural integrity under thermal and mechanical stress
• Long service life with minimal deformation in extreme temperature conditions

Our engineering team designs and manufactures safe, reliable, and efficient H-fin tubes tailored to specific customer requirements. All products are manufactured under strict quality assurance systems to deliver optimal heat transfer efficiency with minimal flue gas resistance in compact installations.
