Product Overview
The DN1800 PN6 Custom Flexible Joint is a pinnacle of engineering designed specifically for the extreme conditions of Power Plant Flue Gas Desulfurization (FGD) systems. Handling slurry with high chemical aggressiveness requires more than a standard solution; this rubber expansion joint features a full PTFE lining integrated into a hand-built EPDM carcass, providing an impenetrable barrier against acidic media and abrasive particles.
With a 350mm face-to-face length, this large-diameter rubber compensator is engineered to absorb massive thermal expansions and vibrations in FGD ducting. Our hand-layered construction ensures that the structural reinforcement is optimized for PN6 pressure ratings, while the SS304 flanges and Full Face Sealing design eliminate leak paths and corrosion at the connection points.
Key Features
- Superior Chemical Resistance: The integrated PTFE lining offers near-universal chemical inertness, specifically protecting the EPDM bellows from the corrosive slurries found in FGD scrubbers.
- Hand-Built Structural Integrity: For a massive DN1800 size, our manual winding process allows for precise placement of high-tenacity reinforcement plies, ensuring a higher safety factor than mass-produced alternatives.
- 100% Custom-to-Drawing: We specialize in solving complex engineering gaps. Whether you need specific flange drilling, non-standard lengths, or vacuum rings for suction lines, we build exactly to your CAD blueprints.
- Full Face Sealing Interface: The PTFE/EPDM face extends to the outer edge of the SS304 flanges, providing a continuous, leak-proof sealing surface that protects the metal flanges from corrosive media.
- Vibration & Noise Isolation: High-elasticity EPDM construction dampens mechanical vibrations from large-scale desulfurization pumps and blowers.
Applications
- Power Plant FGD Systems: Inlet and outlet piping for limestone slurry pumps and absorbers.
- Chemical Processing: Large-diameter acidic fluid transfer lines where metal bellows would fail.
- Water Treatment: Handling chemically treated industrial wastewater in heavy industries.
- Mining & Slurry: Transporting abrasive media where chemical resistance is also a priority.
FAQ
Q: How do your custom DN1800 joints solve the specific challenges of power plant FGD systems?
A: FGD systems are notorious for destroying standard piping components. Our custom flexible joint addresses these engineering “pain points” through:
- Anti-Corrosion Synergy: We combine the structural flexibility of a rubber expansion joint with the chemical “shield” of PTFE. This hybrid design prevents the premature swelling or cracking of the EPDM when exposed to harsh desulfurization chemicals.
- Precision Engineering for Large Bore: A DN1800 joint is a critical point of failure. By using a hand-built process, we can reinforce the “shoulders” of the arch specifically to handle the weight of the slurry and the internal pressure, preventing the “ballooning” effect often seen in low-quality joints.
- Direct Drawing Compliance: Power plant retrofits often involve mismatched pipe gaps. Because we are a drawing-based manufacturer, we can adjust the 350mm length or flange thickness to match your existing site conditions perfectly, ensuring a stress-free installation.
- SS304 Material Security: We use high-quality SS304 for the flanges to prevent external atmospheric corrosion in the humid, sulfur-rich environment of a power plant, ensuring the joint remains serviceable for its entire design life.
