Product Description
DELLOK Nailhead Tube for Corrosive Environments
DELLOK studded tubes (nailhead tubes) are engineered for high-temperature, corrosive industrial applications where conventional finned tubes are unsuitable due to heavy fouling or aggressive cleaning requirements.
Product Overview
Studded tubes feature resistance-welded studs that significantly increase heat transfer surface area while providing superior durability in harsh operating conditions. These tubes are commonly used in petroleum refineries, fired heaters, boilers, and chemical processing equipment.
Key Advantages
- Enhanced heat transfer efficiency equivalent to 4-10 bare pipes
- Superior resistance to corrosive environments and high temperatures
Manufacturing Process
Studs are automatically welded to tubes using precision electric resistance welding with PLC-controlled parameters, ensuring consistent weld quality and structural integrity.
