Product Description & Specifications

Product Overviewย 

The DN65 PN25 Marine Rubber Compensator is a high-end flexible solution engineered specifically for the harsh environments of ship chemical piping. This marine rubber expansion joint combines the robust pressure resistance of an EPDM carcass with a fully integrated PTFE liner, providing universal resistance against corrosive cargo and chemicals handled by modern vessels and tankers.
To address the extreme space constraints in ship engine rooms and pump modules, we provide a specialized milled flange service. While the bellows maintain a standard 115mm length, the SS316 flanges are precision-milled according to your CAD drawings to ensure a perfect fit in compact marine installations. Our product serves as a top-tier quality replacement for global premium brands, delivering reliable shipboard performance with a shorter lead time.

Key Featuresย 

  • Ship-Grade Chemical Resistance: The PTFE lining creates an impenetrable barrier, protecting the marine rubber compensator from aggressive acids and solvents found in chemical tankers.
  • Space-Saving Milled Flanges: We solve shipboard installation issues by milling SS316 flanges to your exact drawings, reducing the footprint in tight vessel compartments.
  • Marine-Grade SS316 Construction: Specifically selected for its resistance to salt-spray and maritime corrosion, ensuring long-term durability at sea.
  • High-Pressure PN25 Reliability: Precision-molded for ship piping systems that demand a high safety factor (2.5MPa) during fluid transfer.
  • Rapid Delivery for Ship Refits: We understand that vessel downtime is costly; we provide high-quality customized solutions much faster than traditional international suppliers.

Applicationsย 

  • Chemical Tankers & Oil Vessels: Flexible links for cargo handling and aggressive chemical transfer.
  • Ship Scrubbers & Fuel Modules: Reliable connections in corrosive marine exhaust and fuel treatment systems.
  • Offshore Engineering: High-pressure chemical lines on FPSOs and drilling rigs.

ย FAQย 

Q: How do your custom-milled flanges solve space-saving problems for ship engineers?
A: On a ship, every millimeter of space is valuable. Our marine rubber flexible joint is designed to solve real-world vessel piping challenges:
  1. Custom-to-Drawing Solutions: We don’t just sell standard parts. If your ship’s piping layout is too compact for a standard flange, we can mill the SS316 flanges according to your blueprints, ensuring the joint fits perfectly into existing modules.
  2. Universal Maritime Compatibility: The PTFE lining allows one ship rubber expansion joint to handle various chemicals, reducing the need to stock multiple spare types in the vessel’s inventory.
  3. High-Pressure Marine Security: Despite the custom milling, every unit is pressure-tested to verify its PN25 rating, matching the safety standards of global premium brands like Trelleborg for maritime use.
  4. Optimized Lead Times for Marine Repairs: We offer the precision of custom engineering with the speed of standard production, ensuring your ship refit stays on schedule.
