ASTM A312 TP316L Studded Finned Tube For Heat Exchange Systems
Studded finned tubes are manufactured through resistance welding of studs onto bare tubes. The fins are created by welding fin material, which consists of studs or rods, to the tube base using resistance welding technology.
Manufacturing Process & Advantages
Electricity passes through both the tube and the stud base during welding. The stud shape is specially designed to facilitate the welding process. During fin welding, the stud is mechanically pressed against the tube at the weld point, resulting in an excellent mechanical bond. This type of finned tube performs exceptionally well under high pressure and high temperature conditions.
The mechanical connection is extremely robust, making these tubes suitable for applications with extreme mechanical stresses, such as during machining or cleaning processes.
Applications
These finned tubes are used in finned tube bundles, air coolers, heat exchangers, and similar equipment. They are the preferred choice for industries including petrochemical plants, power generation facilities, chemical processing plants, and steel mills.
Key Features
- Manufacturing Process: Resistance welding
- Tube Bonding: Excellent
- Heat Transfer Efficiency: Excellent
- Mechanical Resistance: Excellent (can withstand frequent high-pressure cleaning, reducing downtime and extending service life)
- Corrosion Protection: Provides excellent protection for the base tube by fully covering it (except for exposed ends)
- Temperature Range: Dependent on material properties of fins (studs) and tubes
