Overview
The EUROTECH XTR60 Tube Forming Extrusion Line is a fully integrated, CE-certified industrial system engineered for the continuous conversion of metal strip (typically stainless steel, carbon steel, or aluminum alloys) into precision-welded, round, seamless-appearing tubing. Unlike conventional polymer extruders, this system operates on a cold-forming principle: it combines roll forming, TIG (Tungsten Inert Gas) welding with argon–hydrogen shielding gas mixtures, in-line roundness correction, longitudinal straightening, and precision cutoff — all within a single synchronized production line. The process eliminates the need for secondary drawing or annealing in many applications, delivering dimensional stability, consistent wall thickness, and high surface integrity. Designed for 24/7 operation in ISO 9001-certified tube manufacturing facilities, the XTR60 meets mechanical and electrical safety requirements per EN 60204-1 and electromagnetic compatibility standards per EN 61000-6-2.
Key Features
- Modular roll-forming station with CNC-machined, hardened steel forming rolls (standard 8–12 station configuration), enabling rapid profile changeover for diameters from Ø12 mm to Ø60 mm and wall thicknesses ranging from 0.3 mm to 2.5 mm.
- High-frequency TIG welding unit with programmable arc current ramping, real-time arc voltage monitoring, and dual-gas (Ar + 3–5% H₂) delivery for oxide-free fusion and reduced porosity in austenitic stainless steels.
- Integrated sizing and roundness correction module utilizing adjustable mandrel-and-die assemblies with hydraulic pressure control, ensuring O.D. tolerance ≤ ±0.08 mm and ovality < 0.15% across production runs.
- Post-weld inline straightening unit with multi-point, servo-controlled bending rollers and automatic deflection compensation — capable of achieving straightness ≤ 0.3 mm/m over lengths up to 12 m.
- Hydraulic shear cutoff system with programmable length setting (±0.2 mm repeatability), blade synchronization to line speed, and chip-free cutting geometry optimized for burr minimization.
- Optional pre-feeding subsystem including motorized decoiler, accumulator loop, and resistance spot welder for continuous strip joining — supporting uninterrupted operation during coil changeovers.
Sample Compatibility & Compliance
The XTR60 accommodates cold-rolled, pickled, or bright-annealed metallic strip substrates conforming to ASTM A240, EN 10088-2, or JIS G4305 specifications. Compatible materials include AISI 304, 316L, 430, and 2205 duplex grades, as well as low-carbon steels (e.g., DC01, SPCC) and 1xxx/3xxx/5xxx aluminum alloys. All electrical cabinets carry CE marking; machine safety complies with EN ISO 13857 (safe distances) and EN ISO 14120 (guarding). Optional validation packages support IQ/OQ documentation per GMP Annex 15 for pharmaceutical-grade tubing production.
Software & Data Management
The line is controlled via a Siemens SIMATIC S7-1500 PLC with a 10.1″ HMI panel running WinCC Runtime Advanced. Process parameters—including roll gap settings, welding current/voltage, travel speed (0.5–30 m/min), and cutoff length—are stored in encrypted project files with timestamped revision history. Audit trail functionality logs all operator interventions, parameter modifications, and alarm events in accordance with FDA 21 CFR Part 11 requirements when configured with electronic signature modules. Exportable CSV reports include weld seam inspection data (via optional integrated eddy-current probe), dimensional measurement logs, and maintenance cycle alerts.
Applications
- Manufacture of sanitary tubing for food & beverage processing (3A-compliant finishes achievable with post-line polishing)
- Production of instrument air lines, hydraulic conduits, and heat exchanger tubes meeting ASME B31.1/B31.3 design codes
- Supply of precision capillary tubing for medical device OEMs (e.g., catheter shafts, biopsy needles)
- High-volume fabrication of structural hollow sections for architectural and automotive sub-assemblies
- On-site pilot-line deployment for material qualification testing under ASTM E8/E21 tensile protocols
FAQ
What strip widths and thicknesses does the XTR60 accept?
Standard configuration supports strip widths from 150 mm to 650 mm and thicknesses from 0.3 mm to 2.5 mm. Custom roll sets are available for narrower or thicker gauges upon engineering review.
Is post-weld heat treatment (PWHT) required for stainless steel tubing produced on this line?
Not inherently — the low-heat-input TIG process and controlled cooling rate minimize sensitization in 304/316 grades. However, PWHT per ASME BPVC Section VIII may be specified for critical pressure applications.
Can the system integrate with existing MES or ERP platforms?
Yes — OPC UA server interface is standard; Modbus TCP and Siemens S7 protocol gateways are available as factory-installed options for direct SCADA or SAP ME connectivity.
What level of operator training and technical support is provided?
EUROTECH delivers 5-day on-site commissioning and operator certification, including preventive maintenance scheduling, troubleshooting flowcharts, and spare parts cross-reference documentation. Remote diagnostics via TeamViewer is supported under annual service agreements.
