Product Description & Specifications

Overview

The DN200 Marine Rubber Compensator is a high-performance flexible joint specifically developed for corrosive seawater environments. Equipped with BFe10-1-1 (90/10 Copper-Nickel) flanges, this joint ensures perfect electrochemical compatibility with Cu-Ni piping systems, effectively eliminating galvanic corrosion.
This product carries the prestigious ABS (American Bureau of Shipping) Type Approval, meeting the stringent safety and quality standards required for international maritime vessels. It is the definitive solution for managing vibration and thermal expansion in critical shipboard cooling and ballast networks.

Key Features

  • Anti-Corrosive BFe10-1-1 Flanges: Also known as CuNi 90/10, these flanges offer exceptional resistance to pitting, crevice corrosion, and high-velocity seawater erosion.
  • ABS Type Approved: Fully certified for marine use, ensuring compliance with international maritime insurance and safety regulations.
  • Natural Anti-Fouling: The copper-nickel alloy naturally inhibits the growth of marine organisms (barnacles/algae) on flange surfaces, maintaining system efficiency.
  • Premium EPDM Bellows: High-resilience EPDM provides superior damping of engine room vibrations while offering excellent aging resistance in salty atmospheres.
  • Elimination of Galvanic Stress: Designed to be used in conjunction with Cu-Ni pipelines to prevent the accelerated corrosion common with dissimilar metal joints.

Applications

This rubber compensator is ideal for:

  • Marine Seawater Cooling Systems: Connecting main engine coolers and heat exchangers.
  • Shipboard Ballast & Bilge Lines: Managing high-salinity water intake and discharge.
  • Offshore Platform Firefighting Water: Reliable flexible connection for fire-main headers in salt-spray environments.
  • Desalination Plant Intake: Providing corrosion-free joints for raw seawater suction lines.
