Our annual capacity exceeds 20,000 tons of aluminum processing and 12 million meters of finned tubes.
Quality assurance is integrated throughout our entire production process, with systematic sampling and testing for every batch to ensure product reliability.
Studded Tube Product Overview
Studded tubes feature welded studs arranged in specific formations along metal tubes to increase surface area for enhanced heat transfer efficiency. These components are essential in boilers, refineries, and reheating applications.
Manufacturing Process
Steel studs are precision-welded onto base tubes, available in cylindrical, elliptical, or lens-type configurations.
Key Advantages
- Superior connection surface with minimal heat loss
- Welding connection rate exceeding 90%
- No welding power required with minimal welding tumor formation
- Narrow heated surface zone preserves base tube structural integrity
- Automated welding parameters ensure consistent quality and eliminate manual operation variability
Product Properties
- Space-efficient compact design
- Exceptional durability for harsh environments
Industrial Applications
Studded tubes are extensively used in heat recovery systems for petrochemical plants, oil & gas facilities, and chemical processing operations. They perform reliably in convection ovens and extreme temperature conditions with corrosive elements like sulfuric acid.
