Custom Titanium Alloy Subsea Pressure Housings

Product Overview 

Our Custom Titanium Alloy Subsea Pressure Housings are precision-engineered to protect critical electronics, sensors, and instrumentation in the world's most demanding underwater environments. Manufactured from premium-grade titanium alloys GR5 (Ti-6Al-4V), these housings deliver an unmatched combination of lightweight strength, seawater corrosion resistance.

Whether you are deploying autonomous underwater vehicles (AUVs), remotely operated vehicles (ROVs), ocean landers, or subsea observation systems, our custom titanium alloy subsea pressure housings provide the secure, leak-proof enclosure your mission depends on.

Advantages

Extreme Strength-to-Weight Ratio: Titanium Grade 5 offers tensile strength comparable to many stainless steels but at nearly 45% less weight. This dramatically reduces the displacement and payload burden on AUVs, ROVs, and towed arrays.

Tailored Customization: Our core competency is the realization of your unique design requirements. We offer complete custom formatting for dimensions, wall thickness , end-cap configurations, and internal mounting interfaces.

Precision Machining: CNC-turned, milled, drilled, and threaded with tight tolerances to ensure perfect O-ring sealing and component fit.

Applications

Remotely Operated Vehicles (ROVs): Protection for telemetry systems, hydraulic power units, and control electronics.

Subsea Sensor Packages: Deployment of sensitive instruments like hydrophones, CTDs, or magnetometers.

Underwater Camera Systems: Pressure housings with integrated optical ports for deep-sea photography and video.

Subsea Power Distribution: Sealed enclosures for transformers, switches, and connectors.

Deep-Sea Drilling Equipment: Monitoring tools and data-logging enclosures.

Customization Options

• Geometry: cylindrical, spherical, hemispherical.

• Material grade:GR5, or GR5 ELI for full-ocean-depth.

• End ConfigurationsEnd caps, flanges, bulkheads, and penetrator.

• Surface finishes: Sandblasting, anodizing, etc.

Why Titanium？

Titanium is the material of choice for deep-sea pressure vessels. Its strength-to-weight ratio is superior to steel – approximately 44% lighter – significantly improving buoyancy, reducing power consumption, and simplifying deployment logistics . The naturally formed oxide layer provides exceptional resistance to chloride attack in seawater, eliminating concerns over corrosion fatigue and galvanic corrosion.
