Advanced Welded Pipe Production Lines

TIG produces dense, clean welds ideal for sanitary fluid tubes in food, beverage, and pharmaceutical applications where inner surface roughness, inclusions, and porosity are critical. It pairs well with ultrasonic cleaning and inner polishing, and meets ASTM A270 to support entry into high-end export markets.

Check rated duty cycle (e.g., 95%), air/water cooling options, and pump specs (head and flow). For example, UTS‑500 offers 95% duty cycle, air/water cooling, up to 35 m head and 30 L/min flow—ensuring long, stable welding and consistent seams with minimal current fluctuation.

Typical ranges: outer shielding 1.5–15 L/min, inner shielding 3–30 L/min, gas inlet pressure 0.2–0.5 MPa. Tune by material, wall thickness, and line speed to balance protection and cost, preventing oxidation from under‑shielding and waste from over‑shielding.

Maintain 380 V ±10% power quality, ambient −10 to +40 °C, and chiller settings around 25 °C for torch coolant. Keep adequate clearance around equipment to limit thermal drift and spatter—stabilizing the arc and weld consistency while reducing defects and downtime.

For thin‑wall, small seams sensitive to centerline deviation, consider photoelectric or vision tracking (e.g., TIG‑SJ). This improves weld consistency and yield, reduces manual adjustments, and lowers rework costs.

Use small stepwise speed increases with inner/outer shielding and current ramp scans. Combine melt pool/weld visualization with borescope and pressure tests to define a stable line speed. Pre‑verify straightness on forming/squeeze units when needed to scale throughput without sacrificing sanitary weld quality.

Our standard TIG welding lines deliver stable operation at speeds of 3–6 m/min, processing pipes with a wall thickness of 0.3–6 mm. This setup is ideally suited for achieving an annual production output of 2,000–5,000 tons, providing a robust and efficient solution for medium-scale manufacturing requirements.

TIG welds meet ASTM A269/A270 and EN 10217‑7 and are widely adopted in food, pharmaceutical, and semiconductor sectors—supporting smooth third‑party testing and market access in Europe and North America.

Typical TIG lines run at 20–30 kW with 40–50 kVA electrical capacity. Plan for 70–100 m length and 6–8 m width to avoid retrofits or costly site changes later.

Common uses include beverage transfer piping, pharmaceutical sanitary fluid tubes, drinking water treatment piping, and laboratory high‑purity lines. Benchmarking against these scenarios helps confirm TIG process fit and avoids mis‑selection.
