With exports to 60+ countries, our TIG/Orbital Welded Tubes are widely used in WFI lines, purified water loops, vaccine manufacturing, dairy processing, beverage plants, fermentation systems, and analytical instrumentation circuits, making INOX STEEL INDIA a trusted partner for high-purity tubing worldwide.
TIG welded tubes are produced using a controlled electric arc to fuse tube edges, ensuring:
Orbital welding is a fully automated, computer-controlled, filler-less welding process where the torch rotates 360° around the tube. This produces:
Orbital welding is the gold standard for: WFI Lines, Injectable Drugs, Vaccines & Biologics, Pure Steam, and High-purity instrumentation.
TIG / Orbital Welded Tubes undergo a precise engineering cycle to ensure zero contamination and sterile flow:
