Saltwater-Proof Titanium Underwater Housing for Cameras

Product Introduction 

Saltwater-Proof Titanium Underwater Housing for Cameras — Marine-Grade Titanium Enclosure for Extreme Depth Applications

Engineered for professionals who demand zero compromise in extreme underwater environments, the Saltwater-Proof Titanium Underwater Housing for Cameras is precision-machined from Grade 5 Ti-6Al-4V titanium alloy, delivering a 1,000m depth rating with an IP69 protection level. It has a tiny form factor of only 2.5kg and 190×100×90mm, offering both strength and low weight. It has a self-healing TiO₂ oxide layer that gives lifetime anti-corrosion protection against chloride pitting in sea water. This enclosure is suitable for maritime and diving applications and is compatible with underwater lighting systems and may be completely customized to your designs and requirements.

Product Application

Deep-Sea ROV and AUV Systems for oil and gas pipeline inspection and research survey at depths more than 3,000m when freshwater cleaning between dives is not possible, mounted on remotely controlled or autonomous underwater vehicles

Long-Term Seafloor Observatories — Deployed on static benthic nodes for 1–5 year unattended operation, protecting 4K/8K sensors from biofouling-induced corrosion and long-term pressure fatigue.

Professional Marine Cinematography — Used by wildlife film crews working in high-current reef environments, where Saltwater-Proof Titanium Underwater Housing for Cameras' self-healing oxide layer prevents structural deterioration after contact with reef surfaces.

Why Choose Our Saltwater-Proof Titanium Underwater Housing for Cameras

Aluminum becomes rusty. The pressure on the polycarbonate. Stainless steel is just too hefty. Titanium addresses all three difficulties simultaneously.

Grade 5 Ti-6Al-4V has an 895-1,000 MPa tensile strength, just over twice that of 316L stainless steel, and a density of just 4.43 g/cm3 makes your deployment system nimble. The naturally generated TiO₂ layer is chemically inert in seawater up to 260°C, preventing galvanic pitting and crevice corrosion that degrade anodized aluminum after extended contact to saltwater.

The non-magnetic design avoids electromagnetic interference to ROV magnetometers and navigation compasses. O-ring seal integrity is uniform across thermoclines during deep dives due to low thermal expansion.

Manufacturing Process

Every housing starts with certified titanium billet. Complex geometries and precise sealing surfaces are achieved using CNC machining, 5-axis CNC machining, turning, milling, drilling and thread machining.

Critical sealing grooves are cut to tolerances measured in microns. CMM and micrometers are used to perform specific in-process dimensional inspections on O-ring seats, viewport interfaces and threaded features.

Secondary operations include deburring, surface finishing, and assembly. Forging and precision forging are available for structural components requiring enhanced grain refinement and mechanical integrity.

Quality Control

All housings are tested for hydrostatic pressure, and dimensions are verified using a CMM as well as O-ring groove tolerance check. NDT procedures that check weld points and structural integrity include ultrasonic testing and dye penetrant examination.

Material certification comprises Mill Test Certificates (MTC) showing chemical composition, hydrogen concentration, and conformance to ASTM B348. The surface roughness of sealing faces is measured and recorded before shipping.

Certifications

Our manufacturing plant is certified with ISO 9001 quality management system, from raw material verification to final inspection. All titanium materials conform to worldwide standards of ASTM, AMS, ASME and DIN.

FAQ

Q: Grade 2 or Grade 5 — which is better for my application?

A：Grade 5 (Ti-6Al-4V) suits deep-sea and high-pressure use due to superior tensile strength and thinner allowable wall thickness. Grade 2 offers slightly better corrosion resistance and works well for shallow-water deployments.

Q: Will titanium cause galvanic corrosion on my aluminum ROV frame?

A：Yes — titanium is more noble than aluminum in seawater. Use PEEK or Delrin isolation washers to electrically separate the housing from aluminum structural members.

Q: Can the viewport compromise the waterproof rating?

A：The glass-to-titanium seal is the most critical interface. We precision-machine the viewport seat to prevent unequal stress loading. Sapphire or borosilicate glass with redundant O-ring sealing is recommended for deep applications.

Q: Do you support custom depth ratings beyond 1,000m?

A：Yes. Wall thickness, geometry, and sealing systems are all adjustable. Full Ocean Depth configurations for 11,000m environments are achievable through custom engineering.

Q: What documentation is provided?

A：Each order includes material certificates, CMM inspection reports, pressure test records, and full traceability documentation.
