Studded Finned Tubes
Anand Seamless Ltd. manufactures Studded Finned Tubes using precision electric resistance welding (ERW) technology to fuse metal studs directly onto the outer surface of seamless tubes. This high-strength bonding method ensures that each stud is welded with full fusion for maximum thermal efficiency and structural integrity.
Studded fin tubes are ideal for applications involving:
- High-temperature flue gases
- Aggressive corrosion or fouling
- High-pressure environments
By increasing the external surface area, studded tubes improve heat transfer while minimizing the risk of corrosion under the fins. Their rugged construction allows for long service life and easy cleaning under demanding process conditions.
