Valve for Marine and Shipbuilding Industry

Marine piping systems expose Valve to seawater, salt-laden atmospheres, vibration and limited installation space. Speciality Valve offers corrosion-resistant valve solutions for shipbuilding, seawater systems, offshore installations and onboard fluid handling. Materials chosen and valve design are suitable to seawater environment, pressure, service and available space at the installation point.

Marine Valve Applications on Ships:

Shipbuilding Valve is required in:

Sea-water intake systems
Sea chests
Ballast-water systems
Bilge pipelines
Main-engine cooling
Fire-main lines
Fuel-oil systems
Lubrication lines
Freshwater systems
Cargo-transfer pipelines
Pump suction and discharge
Offshore utility systems

Valve Types for Marine Piping:

Butterfly Valve – Compact isolation for ballast and seawater lines
Ball Valve – Fast quarter-turn shut-off
Gate Valve – Straight-through isolation
Globe Valve – Flow regulation in utility systems
Check Valve – Pump and pipeline backflow protection
Safety Valve – Pressure-equipment protection
Bronze Valve – Selected seawater and marine duties
Aluminium Bronze Valve – Demanding seawater and chloride exposure
Cryogenic Valve – Qualified LNG marine applications

Best Valve Materials for Marine and Seawater Service:

Aluminium Bronze Valve – Widely suited to seawater cooling, ballast and marine piping
Bronze Valve – Used for selected shipboard water and utility systems
Duplex Valve – Suitable for chloride-bearing seawater applications
Super Duplex Valve – Used for demanding offshore and high-chloride seawater service
Monel Valve – Suitable for selected seawater and marine applications
Titanium Valve – Used where very high resistance to seawater corrosion is required
Seawater Corrosion and Galvanic Compatibility:
Seawater contains chlorides and acts as an electrolyte, making corrosion control particularly important.
Engineers should consider:
Pitting resistance
Crevice corrosion
Galvanic compatibility
Seawater velocity
Stagnant conditions
Fastener material
External marine atmosphere
Cathodic-protection interaction
Speciality Valve manufactures marine Valve and shipbuilding Valve for seawater, ballast, bilge, coolant and fuel handling applications. Corrosion resistant materials, compact designs, actuation, testing and documentation can be specified according to vessel requirements.
