Guided Tail Fin

Technical Specifications & Heavy-Scale Capabilities

Strict Shipbuilding-Grade Quality Control & Safety

To comply with international maritime safety and classification society standards, this large-scale structural piece is verified with complete zero-defect assurance:

• Linear Distortion & Straightness Check: 100% verified using dedicated alignment fixtures and CMM (Coordinate Measuring Machines) to ensure the 80CM length maintains perfect straightness without structural warping.
• Long-Through Hole Integrity: Inspected via industrial video-endoscopes to guarantee the internal tunnel is completely clear, smooth, and free of sand inclusions or shell residues.
• Subsurface Defect Inspection: Conducted via Liquid Penetrant Testing (LPT) and optional ultrasonic/X-ray testing to ensure no micro-voids, shrinkage cavities, or thermal tears exist within the 31.12kg solid metal body.
• Marine Material Verification: 100% analyzed by Spectrometers to ensure strict low-carbon and Molybdenum chemistry, vital for long-term anti-rust performance in offshore salt-spray zones.
