The Corrosion-Resistant Tube for Marine Environments is specifically engineered to withstand the highly aggressive conditions found in seawater, brackish water, and coastal atmospheric applications. Manufactured from molybdenum-bearing austenitic stainless steel or duplex grades, this tube offers exceptional resistance to pitting, crevice corrosion, and stress corrosion cracking caused by chlorides. Its seamless construction eliminates weld-related weak points, ensuring long-term reliability in offshore and marine applications.

PREN = Pitting Resistance Equivalent Number (Cr% + 3.3*Mo% + 16*N%). Higher PREN indicates better chloride resistance.

Tested in accordance with ASTM E8 / E8M.

• Excellent Chloride Corrosion Resistance – Withstands seawater, brine, and salt spray

• High Pitting Resistance Equivalent Number (PREN) – Critical for long-term immersion service

• Stress Corrosion Cracking Resistance – Performs well in high-temperature seawater

• Good Biofouling Resistance – Smooth surface reduces marine organism attachment

• Proven Offshore Performance – Widely used in oil & gas, desalination, and shipbuilding

• Offshore Platforms – Seawater cooling lines, firewater systems, hydraulic lines

• Shipbuilding – Ballast water systems, fuel lines, deck drainage

• Desalination Plants – High-pressure brine piping, reverse osmosis systems

• Subsea Equipment – Umbilicals, flow lines, hydraulic control lines

• Coastal Infrastructure – Bridge drainage, seawater intake structures

• Marine Exhaust Systems – Wet exhaust and scrubber systems

• Aquaculture – Seawater supply and recirculating systems
