Studded Tube for Furnace (ASTM A312 TP304)
Studded tubes are specialized heat transfer components widely used in furnace, waste heat recovery systems, industrial boilers, and process heating equipment. By welding metallic studs uniformly onto the outer surface of the tube, the effective heat transfer area is significantly increased, resulting in enhanced thermal efficiency, improved gas-side heat exchange, and optimized equipment performance.
Our Studded Tubes for furnace are manufactured using ASTM A312 TP304 austenitic stainless steel tubes, offering excellent corrosion resistance, oxidation resistance, and long-term reliability under elevated operating temperatures. The studs are securely welded to ensure strong metallurgical bonding and consistent heat transfer performance throughout the service life of the equipment.
- Manufactured from ASTM A312 TP304 stainless steel.
- Excellent resistance to oxidation and atmospheric corrosion.
- Increased external heat transfer surface area.
- Enhanced thermal efficiency in HRSG applications.
- Uniform stud welding with high bond strength.
- Suitable for high-temperature flue gas environments.
- Reduced equipment footprint through improved heat recovery.
- Reliable performance under cyclic thermal loading.
- Customizable stud dimensions and tube lengths.
