Product Description
DELLOK SCH 40 Studded Finned Tube
High-performance studded finned tubes designed specifically for oil refinery applications, featuring enhanced heat transfer efficiency and corrosion resistance.
Product Overview
Studded tubes are engineered for refining and petrochemical industries, serving as reliable alternatives to high-frequency welded finned tubes in fired heaters and furnaces.
Manufacturing Excellence
Steel studs are automatically resistance welded to the tube surface, creating high-quality forge welds that ensure optimal strength and heat flow.
Key Advantages
- Significantly increases heat transfer surface area - equivalent to 4-10 bare pipes
- Provides excellent corrosion protection by covering the base tube surface
- Easy to clean with high-pressure jets without damage
- Ideal for harsh environments and dirty fuel applications
- Superior mechanical resistance for extended service life
