Product Overview
The DN65 PN40 Custom Flexible Joint is a high-integrity engineering solution specifically developed for the extreme pressures and oil-intense environments of marine hydraulic systems. Operating at a working pressure of 40 Bar (4.0MPa), this rubber expansion joint utilizes a premium NBR (Nitrile) liner, providing exceptional resistance to mineral oils and hydraulic fluids.
Constructed via a meticulous hand-built (hand-layered) process, the bellows are reinforced with high-tenacity synthetic plies to ensure maximum structural stability. A key technical advantage is our integrated vulcanization technology, where the NBR sealing face and the SS316 flanges are fused into a single, inseparable unit. Designed as a top-tier quality replacement for global premium brands, this joint is equipped with safety control units to prevent over-extension in high-vibration shipboard environments.
Key Features
- Integrated Vulcanized Sealing: The rubber carcass and SS316 flanges are vulcanized as one, providing a leak-proof “monoblock” interface that excels under high-frequency pulsations.
- Oil-Resistant NBR Construction: Specifically formulated to prevent swelling and degradation when exposed to hydraulic oils (HLP, HM, HV) and lubricants.
- PN40 Rated Hand-Building: Manual winding of reinforcement layers offers a superior safety factor that matches the performance benchmarks of international premium manufacturers.
- Safety Control Units: Integrated limit rods protect the rubber compensator from axial over-extension during intense hydraulic surges.
- 100% Custom-to-Drawing: We solve complex installation issues by manufacturing to your precise 175mm technical drawings, ensuring zero-stress piping alignment.
Applications
- Marine Hydraulic Power Units (HPU): High-pressure discharge lines for steering and deck machinery.
- Ship Steering Gear Systems: Absorbing shocks and damping vibrations in critical maneuvering lines.
- Offshore Cranes & Winches: Reliable flexible links for heavy-duty deck hydraulics.
FAQ
Q: How does this custom hand-built joint serve as an equivalent quality replacement for global premium brands in PN40 hydraulics?
A: Our custom flexible joint is engineered to meet and exceed the benchmarks set by top-tier global manufacturers through:
- Equivalent Structural Reliability: Much like the industry’s most respected series, our hand-built rubber expansion joint undergoes a manual layering process that ensures the bellows maintain geometric stability under 40 Bar pressure.
- Seamless Vulcanized Interface: While standard joints rely on loose gaskets, our integrated vulcanization fuses the NBR directly to the SS316 flanges. This creates an impenetrable seal that is essential for maintaining zero-leakage in shipboard hydraulic circuits.
- Active Safety Protection: For PN40 duty, the risk of pipe elongation is critical. Our included control units provide a fail-safe mechanism, ensuring the joint operates within safe displacement limits at all times.
- Drawing-Based Customization: We specialize in solving engineering problems. If your installation requires a specific 175mm length, we build according to your CAD drawings to ensure a perfect fit that protects your high-value hydraulic components.
