High Fin Tube
High Fin Tube - seamless steel tube
Welded spiral finned steel tubes for industrial heat exchangers, boilers, waste heat recovery & drying equipment with high heat exchange performance.
Spiral finned tubes are high-efficiency heat transfer elements designed to maximize external surface area while maintaining compact equipment geometry.
The fins are helically wound around a base tube, significantly increasing the effective heat transfer area without enlarging the core footprint. This configuration enhances heat exchange performance, reduces gas-side flow resistance and lowers overall metal consumption.
The base tube is typically manufactured from carbon steel, stainless steel, copper or aluminum. Fins can be produced from the same material or from a higher-conductivity alloy such as copper or aluminum to further improve thermal performance.
In most designs, fins are tension-wound onto the tube to ensure intimate contact and long-term mechanical stability under thermal cycling and vibration.
Mass production welded spiral finned tubes for boiler and waste heat recovery equipment
Our factory adopts full-automatic high-frequency spiral fin welding production lines. The fins are tightly fused with base tube without gaps, low contact thermal resistance, stable structure under long-term temperature fluctuation, no fin shedding risk. This series finned tubes serve as core heat transfer elements for multiple industrial thermal equipment under medium-high temperature working conditions.

Spiral finned tubes are widely used wherever extended surface area is required to compensate for low gas-side heat transfer coefficients, improving thermal efficiency and reducing equipment size.
All spiral finned tubes follow strict full-process quality control:
Ceramic lined pipe is made through self-propagating high-temperature synthesis (SHS) technique.
Cast basalt lined steel pipe is composed by lined with cast basalt pipe, outside steel pipe and cement mortar filling between the two layers.
Ceramic tile lined pipes have very uniform coating of specially formulated ceramic material that is affixed to the inner of the pipe.
The material of the rare earth alloy wear-resistant pipe is ZG40CrMnMoNiSiRe, which is also the grade of rare earth alloy steel.
Tubes Erosion Shields are used to protect boiler tubing from the highly erosive effects of high temperatures and pressures thereby greatly extending tube life.
The ASTM A213 T91 seamless tubes are primarily used for boiler, superheater, and heat-exchanger.
