Welded U-tubes - Steamline Industries Ltd

Stainless Steel Welded U-Tubes

TIG-welded and precision-bent stainless steel U-tubes manufactured to ASTM A249 standards for heat exchangers, condensers, and process equipment.

What Are Stainless Steel Welded U-Tubes?

Stainless steel welded U-tubes are manufactured from high-quality stainless steel strip using advanced TIG welding and precision bending processes. These tubes provide a cost-effective solution for heat exchangers, condensers, and process equipment while maintaining excellent dimensional consistency and corrosion resistance.

At Steamline Industries, our welded U-tubes undergo post-weld annealing and comprehensive non-destructive testing to ensure long-term performance and reliability in demanding industrial applications.
