Customized Industrial Grade Spiral Fin Tubes For High Stiffness Low Flow Resistance

Customized Industrial Grade Spiral Fin Tubes For High Stiffness Low Flow Resistance

What are the common failure modes of Boiler Fin Tubes and how to prevent them?

         Common failure modes include fin-tube bonding separation (due to poor welding/bonding), corrosion (from acidic flue gas), and erosion (from high-velocity dust particles). Prevention measures: use high-quality welding/bonding processes (e.g., TIG welding), select corrosion-resistant materials, install dust collectors to reduce dust content, and regularly inspect the fin-tube surface.

Product Introduction

         The spiral finned tube is a finned tube that is cold-wound at room temperature, and the steel strip is reinforced on the steel tube in a winding way, which is an efficient heat transfer element with spiral fins, and its heat transfer area is several times or even dozens of times that of the plain tube. Spiral fin tubes have been widely used in heat recovery of boiler economizers, air preheaters and waste heat boilers, as well as heat exchange equipment in various fields such as chemical industry and pressure vessels.
