Description
Main Tube Inspection
Quality assurance is integral to our tube mill production lines. Each system incorporates multiple inspection stations for comprehensive quality control throughout the production process. The following inspection procedures ensure that all produced tubes meet applicable international standards and customer specifications.
• Online Eddy Current Testing for continuous weld defect detection with automated marking of suspect sections.
• Hydrostatic Pressure Testing at 5 MPa minimum per EN39 standard to verify weld seam integrity and pipe body soundness.
• Dimensional Inspection of OD (48.3mm ±0.5mm), WT, and length using laser gauging for consistent fitting with couplers.
• Zinc Coating Thickness Test using magnetic induction method, ensuring minimum 40 µm coating per ISO 1461 for corrosion protection.
• Tensile and Yield Strength Testing to confirm pipe mechanical properties meet EN39 Grade S235GT requirements.
Product Features
Our tube mill production lines incorporate advanced engineering features designed to maximize productivity, ensure consistent quality, and provide operational flexibility. The following key features distinguish our equipment in the global marketplace and deliver value throughout the equipment lifecycle.
• Dedicated roll forming tooling optimized for 48.3mm OD scaffolding pipe delivers production speeds up to 100 m/min.
• Quick-change roll cassette system enables size changeover within 30 minutes, supporting flexible production scheduling.
• High-frequency welder with auto-adaptive power control maintains consistent weld quality across varying line speeds.
• Online zinc coating thickness monitoring ensures uniform galvanizing layer for extended service life in outdoor environments.
• Servo-controlled flying saw provides precise cut-to-length with ±2mm tolerance for standardized scaffolding pipe lengths.
