Pipe Fittings for Shipbuilding & Marine Industry
Marine piping systems must withstand constant vibration, saltwater corrosion, and classification society scrutiny. Our class-approved pipe fittings serve newbuild shipyards, ship repair facilities, and offshore vessel operators worldwide.
Applications in Shipbuilding & Marine
Ships and offshore structures contain vast piping networks that are critical to vessel safety and operation. Every fitting must be approved by the relevant classification society and manufactured to strict marine standards:
Propulsion & Engine Room
Main engine cooling, fuel oil service, lubricating oil, starting air, and exhaust piping. Heavy-wall carbon steel and galvanized fittings for continuous operation under heavy vibration.
Bilge & Ballast Systems
Bilge collection, ballast water transfer, and treated water discharge. Galvanized and coated carbon steel fittings resistant to seawater and bilge chemicals.
Cargo & Tank Piping
Cargo oil handling, tank cleaning, inert gas, and venting systems on tankers and bulk carriers. Stainless and carbon steel fittings per cargo type.
Firefighting & Safety
Seawater fire main, foam concentrate, CO2 flooding, and sprinkler systems. Galvanized fittings with classification society type approval.
Classification Society Approvals
All marine pipe fittings must be certified by the vessel's classification society. We supply fittings with certificates from the major class societies:
