クイックアンサー
HYSF underwater connectors are available with depth ratings from 100 meters (10 bar) to 6000 meters (600 bar). Standard product lines typically offer 300m, 1000m, 2000m, 3000m, and 4000m ratings. Custom connectors can be engineered for specific depth requirements beyond standard offerings. All connectors are pressure tested to 1.5x rated depth before shipment.
Standard Depth Ratings
Shallow Water (100-300m)
- アプリケーション Aquaculture, shallow ROV, diving equipment, harbor installations
- Pressure: 10-30 bar (145-435 psi)
- Product series: HYSF-SW series
- Typical cost: Most economical
Medium Depth (300-1000m)
- アプリケーション Work-class ROV, offshore oil & gas, scientific instruments
- Pressure: 30-100 bar (435-1450 psi)
- Product series: HYSF-MD series
- Typical cost: 中程度
Deep Water (1000-3000m)
- アプリケーション Deep sea ROV, subsea production systems, oceanographic research
- Pressure: 100-300 bar (1450-4350 psi)
- Product series: HYSF-DW series
- Typical cost: Premium
Ultra Deep (3000-6000m+)
- アプリケーション Hadal zone exploration, deep submergence vehicles, abyssal research
- Pressure: 300-600+ bar (4350-8700+ psi)
- Product series: HYSF-UD series (custom engineering)
- Typical cost: Highest (custom quoted)
Depth Rating Certification
All HYSF connectors undergo rigorous pressure testing:
- Factory acceptance test: 1.5x rated pressure for 24 hours
- Leak detection: Helium mass spectrometry for critical applications
- Cycle testing: Pressure cycling to simulate operational conditions
- Documentation: Test certificates provided with each shipment
Factors Affecting Depth Rating
素材の選択
- Housing: Titanium (best), stainless steel 316L, bronze, engineered plastics
- Seals: Viton, silicone, polyurethane (selected based on depth and temperature)
- Contacts: Gold-plated brass, stainless steel, or specialty alloys
Design Considerations
- Wall thickness and geometry
- Seal compression and retention
- Pressure balancing (oil-filled vs. dry)
- Cable entry and strain relief
Environmental Factors
- Temperature extremes (affects material properties)
- Salinity and chemical exposure
- Dynamic vs. static pressure loading
- Installation depth vs. maximum rated depth
Custom Depth Solutions
For applications requiring non-standard depth ratings:
- Engineering consultation: Review your specific requirements
- FEA analysis: Finite element analysis for custom designs
- Prototype testing: Validation testing before production
- Certification support: Documentation for class approval (DNV, ABS, etc.)
Depth Rating vs. Working Pressure
| Depth | Pressure (bar) | Pressure (psi) | Test Pressure (bar) |
|---|---|---|---|
| 100m | 10 | 145 | 15 |
| 500m | 50 | 725 | 75 |
| 1000m | 100 | 1450 | 150 |
| 2000m | 200 | 2900 | 300 |
| 3000m | 300 | 4350 | 450 |
| 4000m | 400 | 5800 | 600 |
| 6000m | 600 | 8700 | 900 |
