Product Overview
The DN125 PN25 Marine Rubber Compensator is a premium, hand-built solution engineered for the high-pressure demands of modern vessel piping. Unlike standard molded joints, the hand-layering process ensures a reinforced, high-density EPDM carcass capable of maintaining structural integrity at 2.5 MPa (25 Bar).
Designed specifically for Marine Engineering, this unit features SS304 floating flanges for superior salt-spray corrosion resistance. The specialized asymmetric sealing design—with one RF (Raised/Ring Face) end and one Full-Face end—allows engineers to bridge the gap between different equipment standards (such as pumps to main-line piping) without compromising leak-proof performance.
Key Features
- Superior PN25 Rating: Robust multi-layer reinforcement allows for safe operation in high-pressure ballast, fire-main, and cooling systems.
- Hand-Built Longevity: Each joint is meticulously crafted to ensure uniform wall thickness and enhanced fatigue resistance against marine engine tremors.
- Non-Asymmetric Sealing Geometry:
- RF (Ring Face) End: Provides high-concentrated sealing pressure for specialized marine valves.
- Full-Face End: Offers a broad contact area for standard piping, reducing flange stress.
- SS304 Floating Flanges: Effortless bolt-hole alignment and maximum protection against harsh offshore corrosive environments.
- Single-Arch Design: Minimizes fluid turbulence and prevents the buildup of marine sediment or bio-fouling within the arch.
Applications
- Shipboard Fire-Fighting Mains: High-pressure seawater delivery for emergency response.
- Ballast Water Treatment Systems (BWTS): Reliable flexible links for high-flow transfer lines.
- Central Cooling Systems: Compensating for thermal expansion and vibration in main engine seawater loops.
- Marine Desalination Units: Corrosion-resistant connectors for high-pressure brine and fresh water piping.
FAQ
Q: Why choose an asymmetric (RF to Full-Face) flange configuration for a PN25 marine rubber compensator?
A: In complex shipboard machinery spaces, piping often transitions between different flange standards. This configuration solves three critical engineering challenges:
- High-Pressure Sealing Integrity: The RF (Ring Face) end creates higher unit pressure on the gasket area, which is vital for maintaining a seal at 25 Bar when connecting to precision-machined pump or valve outlets.
- Stress Distribution: The Full-Face end is used on the side connecting to standard piping, distributing the bolt load over the entire flange surface to prevent deformation of the rubber face during the ship’s structural flexing.
- Versatility in Installation: The floating (lap-joint) flanges on both ends allow for 360-degree rotation, making bolt-hole alignment simple even in the confined, “tight-fit” spaces typical of marine engine rooms.
