Sinowon Ultrasonic Hardness Tester: Revolutionary Solution for Pipeline Inner Wall Coating Hardness Measurement

Industry Challenges in Pipeline Coating Hardness Testing
Thin coatings (0.05-0.2mm) with mirror finishes on complex geometries (elbows, deep boreholes) demand innovative solutions beyond traditional Leeb hardness testers:
• Indentation Damage: Leeb methods leave 0.1mm+ visible marks
• Access Limitations: 50% of pipeline inner diameters <100mm restrict conventional tools
• Accuracy Issues: 20-30% HV errors from substrate interference

SU-300 Ultrasonic Hardness Tester: 3 Core Breakthroughs
H2: Non-Destructive Hardness Testing with UCI Technology

• Micro-Indentation (0.003mm)

• 10x smaller than Leeb methods, visible only under 400x microscopy
• MP-1000 probe's magnetic alignment ensures 90°±0.5° measurement accuracy

• Multi-Scale Precision (±1.5HRC)

• Supports HV/HRC/HRB/HB scales with ASTM A1038 compliance
• AI algorithm eliminates 98.7% substrate interference

• Adaptive Pipeline Testing Solutions

• Modular probes: MP-300/500/800/1000 (3N-10N load) for 6mm+ deep grooves
• 500g handheld unit with Bluetooth SPC software (1000-data capacity)

Case Study: Automotive Bearing Coating Inspection
• Problem: Leeb tester caused 0.15mm indentation marks on 0.08mm chrome plating
• Solution: SU-300 achieved:

• Zero visible surface damage
• 6s/measurement (20x faster than Vickers)
• 100% traceable data meeting IATF 16949
