What Are TIG & Orbital Welded Tubes?

TIG Welded Tubes (GTAW – Gas Tungsten Arc Welding)

TIG welded tubes are produced using a controlled electric arc to fuse tube edges, ensuring:

  • Low heat input
  • Minimal oxidation
  • Clean and smooth weld seams
  • High corrosion resistance
  • Suitable for food, beverage & general pharma duties

Orbital Welded Tubes (Autogenous High-Purity Welding)

Orbital welding is a fully automated, computer-controlled, filler-less welding process where the torch rotates 360° around the tube. This produces:

  • Mirror-smooth internal weld (ID)
  • Zero crevice formation
  • Zero entrapment points (bacteria control)
  • Consistency in every weld
  • ASME BPE compliant weld geometry

Orbital welding is the gold standard for: WFI Lines, Injectable Drugs, Vaccines & Biologics, Pure Steam, and High-purity instrumentation.

How TIG / Orbital Welded Tubes Are Manufactured

TIG / Orbital Welded Tubes undergo a precise engineering cycle to ensure zero contamination and sterile flow:

Manufacturing Steps:

  1. Raw Material Selection: High-purity 316L low carbon stainless steel is selected for its exceptional performance against chemicals, sterilization cycles, and cleaning agents.
  2. Forming & Precision TIG Welding: The stainless steel strip is roll-formed and welded using TIG, ensuring a narrow, controlled weld bead with excellent fusion.
  3. Orbital Welding: Advanced machines perform autogenous welding with real-time arc monitoring and uniform 360° weld penetration for crevice-free welds.
  4. Bright Annealing (BA): Restore corrosion resistance, eliminate carbide precipitation, and straighten the grain structure.
  5. Polishing: Depending on application: 0.8 µm Ra (Food/Beverage), 0.4 µm Ra (Pharma SF1), or 0.25 µm Ra (Electropolished SF4).
  6. Passivation & Cleaning: Nitric or citric passivation to remove microscopic contaminants.
  7. Weld Inspection: Boroscopy ensures full penetration, smooth internal weld, and zero pits / cracks / inclusions.
  8. Sterile Packaging: Nitrogen-purged, capped, bagged, and packed to maintain cleanliness.

Key Advantages:

  • Ultra-smooth weld ID (sterile fluids)
  • No crevice, no dead-leg → zero bacterial entrapment
  • Electropolished to 0.25 µm Ra (ASME BPE SF4)
  • Superior corrosion resistance with 316L
  • CIP/SIP resistant for repeated cycles
  • FDA-compatible finishes
  • Consistent welds due to automated process
