H-Finned Tubes

Overview

We operate two automated resistance welding production lines, capable of producing over 70,000 H-finned tubes annually. Steel fins are resistance welded to pressure tubes under controlled conditions to ensure consistent quality and performance.

Our custom-built welding machines provide precise indexing along the full tube length, ensuring accurate fin alignment and consistent attachment throughout production.

We manufacture proprietary single and double steel H-finned tubes in carbon steel, low alloys and stainless steel. Our double-finned tube design improves production efficiency, reduces support requirements and lowers overall installation costs.

Advantages of H-Fin Over Plain Tube

✔ Compact Design: Fewer tubes required, reducing capital investment. Steel H tubes have around 9 times more heating surface than a plain tube of the same length and diameter.

✔ Lower Costs: Capital cost is significantly lower than a plain tube unit for the same duty. Running costs are minimised due to lower pressure drop, decreasing energy consumption by pumps and fans.

✔ Enhanced Efficiency: Larger heating surface ensures quicker and more efficient fluid heating.

✔ Reduced Surface Fouling: Straight flue gas paths throughout the tube bank allow dust particles to pass easily, minimising maintenance requirements.

Design Flexibility

Design flexibility is a cornerstone of our services. We have more than 40 H-fin shapes and sizes, with bespoke designs available to meet specific application needs.

We integrate versatility in shape, geometry, and materials, considering factors such as fuel type, dust load, and operating temperatures, delivering optimised, highly efficient solutions.
