Staubli Corporation - Quick-Release Coupling Systems

Stäubli is an international organization with a worldwide network. Experts in high-quality quick-release coupling systems for more than 50 years, Stäubli develops quick connections for any fluid or other energy circuits that you may need.

Our expertise will help you with all your connector applications either for:

• Mono couplings
• Balanced couplings
• Stab plates

With our expert knowledge of offshore applications and by working closely with our technical staff, we can bring you up-to-date replies to your most specific requirements.

Stäubli Couplings materials and design meet the American Petroleum Institute standards (API code)

Testing techniques adapted to the offshore industry:

• High pressure and high temperature (HP HT)
• Hyperbaric pressure vessel (pressure equivalence: 3,000m)
• Gas under pressure (air, nitrogen, helium) up to 50,000psi
• Oil under pressure up to 58,000psi
• Water up to 100,000psi
• Temperature testing from -110°F to +350°F
• Temperature cyclings
• Thermal shocks

Techniques and materials adapted to an offshore environment (pressure constraints, temperature, corrosion and leak tight seals) and for remote control use (multi-connection and self-aligning).

METAL SEALS

The seals on our couplings may be completely or partially metallic:

• For long term water immersion
• For good resistance to low and high temperatures and pressure
• In order to reduce operating costs due to seal wear and tear

We offer a patented system with self-aligning couplings with metal seals.

COMPENSATION OF MISALIGNMENTS

Our coupling systems allow simple and efficient connection and disconnection on your installations to eliminate maintenance costs caused by misalignment. Provided by:

• A pre-guiding system together with an elastic connection
• Double guiding system
• Swivel couplings

HIGH PRESSURE LEVELS

Stäubli offers you a range of products adapted to demanding pressure and temperature constraints. Well-balanced connections:

• Eliminate the consequences of pressure by a repelling action
• Simplified locking system
• Connection and disconnection under pressure.

Our products are particularly adapted to high flow, and pressure shock.

ANTI CORROSIVE MATERIALS

Materials chosen for a corrosive atmosphere, conforming to the NACE standards.

• Stainless steel
• Inconel®
• Springs in mp35n

Compatible with many fluids, including:

• Corrosion inhibitors
• Methanol
• Glycol water
• Wax inhibitors

MULTI-CONNECTION STAB PLATE

Quick and simultaneous connection of all services is possible: pneumatic, gas, hydraulic and electric. In one movement, all your circuits are connected saving time and optimizing security.

The multi connection stab plate allows ease of maintenance. There is no need to touch the pipe system when interchanging sockets and plugs:

• No tubes to be cut
• No need for welding
• Stab plates for simultaneous energy connections
• A complete solution with hydraulic lines and electrical connectors
• Proven long term reliability

A few samples of applications covered by our products:

• Hydraulic motor supply for winch
• Completion
• Liquid injection via the ROV device
• Seismic analysis
• Fluid injection for Christmas trees, control modules
• Connections between manifold and Christmas trees
• Tool connection via ROV operations
• Automatic push-pull valve coupling for suction pile installation
• Sealing tests on risers and pipelines
• Pipeline welding
• Cooling circuits for the power generators
