Production Process: Engineered for Perfection
VertexFlowtubes’ production process is a masterclass in precision, setting the benchmark for stainless steel piping suppliers:
- Raw Material Selection: Only prime coils from TISCO, POSCO, and Baosteel; 70% recycled content for sustainability.
- Slitting & Forming: High-precision slitting to ±0.05mm; robotic roll-forming for consistent roundness.
- TIG Welding: Nitrogen + argon shielding prevents oxidation; AI-monitored weld penetration.
- Internal Weld Smoothing: Proprietary bead rolling for 100% flush inner seams—critical for sanitary flow.
- Annealing & Pickling: Continuous bright annealing in hydrogen atmosphere; eco-friendly nitric-free pickling.
- Finishing & Polishing: 8-head automated polishers deliver uniform 600# to 8K mirror finishes.
- Quality Control: In-line dimensional scanners, eddy current flaw detection, and third-party SGS/TUV audits.
- Packaging & Traceability: QR-coded labeling, protective capping, and export-grade crating.
This closed-loop system ensures zero rework and 99.97% first-pass yield—statistics few stainless steel piping suppliers can match.
