SEA-CURE - The Condenser Solution

SEACURE Condenser Tubing Logo

Our super ferritic SEA-CURE® is the most cost effective tubing solution for applications where Titanium, Admiralty Brass and Copper-Nickel are causing unwanted outages.

SEA-CURE boasts:


This alloy is specifically designed for applications where chloride induced pitting, crevice and stress corrosion cracking may be encountered. Plymouth's  SEA-CURE stainless steel is used in Electric Power Plant Condensers and Feedwater Heaters, BOP Exchangers, Various Chemical, Petrochemical and Refining Applications, and Desalination Heat Exchangers.

    • The ferritic structure of SEA-CURE stainless steel provides a high strength/low work hardening material with good ductility.
    • These properties allow high design stress limits with good fabrication characteristics. Because of the nickel addition, SEA-CURE has a lower ductile-to-brittle transition temperature than similar ferritic steels without nickel additions.
    • Significantly higher modulus that allows the use of a lighter wall with less problem of vibration
    • Higher steam and water droplet erosion resistance allowing a greater cushion in cases where upset conditions may occur
    • Weldability to other stainless steels
    • Higher strength and modulus which allows more tolerance for those tough designs and installations
    • Over 30 years of commercial history with an outstanding performance record
    • Superior Corrosion Resistance
