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.

The 13Cr pins add some cost, but for sour service in furnaces, it's worth it. Already seeing longer run times between turnarounds compared to before.

Good oxidation resistance, matches well with the T9. No scaling or thinning noticed.

the SS409 pins resist sulfur corrosion better than carbon steel pins we used earlier. In furnace service, that means longer runs between maintenance.
