Premium TA2 Titanium Flanged Rubber Flexible Joint for CCS Class Vessels | Custom-to-Drawing Solutions with Rapid Short Lead Times
Product Overview
This standard 115mm face-to-face DN65 rubber expansion joint is engineered in strict compliance with the CB/T 46-2007 marine standard, fully type-approved to meet rigid CCS (China Classification Society) certification requirements. Configured with premium TA2 (Grade 2 Pure Titanium) flanges and a rated working pressure of PN10, this heavy-duty rubber flexible joint is purpose-built to survive the most corrosive marine piping environments where standard galvanized or stainless steel components suffer rapid pitting failure.
The main expansion bellow is synthesized from high-density, multi-layered EPDM rubber reinforced with high-tensile synthetic fabric tire cord. This configuration provides exceptional structural elasticity, dampening high-frequency mechanical vibration and absorbing multi-axis thermal displacements simultaneously.
By integrating TA2 titanium flanges, this unit provides absolute galvanic corrosion immunity against high-velocity seawater, making it the definitive choice for critical shipboard systems. While this unit follows standard 115mm specifications, our facility specializes in full custom-to-drawing engineering. We provide bespoke soft-connection solutions based on your specific CAD blueprints, combining high-precision manufacturing with exceptionally short lead times to minimize vessel downtime.
Key Features
-
- TA2 Pure Titanium Flanges: Grade 2 titanium construction guarantees absolute immunity to chloride-induced pitting, crevice corrosion, and erosion under high-velocity seawater flow.
- CB/T 46-2007 & CCS Compliance: Fully certified for marine application, meeting all testing, pressure boundary, and material tracing protocols required by the China Classification Society.
- High-Density EPDM Rubber Bellow: Formulated for extreme ozone, UV, and thermal aging resistance, maintaining geometric stability under continuous PN10 hydraulic loads.
- 115mm Standard Face-to-Face: Drop-in dimensional compatibility for standard marine piping layouts, allowing swift integration during routine maintenance or fleet overhauls.
- Vibration & Shock Attenuation: The engineered elastomer profile effectively dampens structural noise and isolates hydraulic pulsations generated by high-RPM shipboard machinery.
- Rapid Delivery Cycles: Optimized production sequencing and responsive raw material inventory allow us to execute short lead times, ensuring critical parts reach the shipyard on schedule.
Applications & Equipment
-
- Central Seawater Cooling Systems: Installed directly at the suction and discharge ports of seawater circulation pumps and plate heat exchangers (PHE) to isolate structural vibrations.
- Ballast Water Management Systems (BWMS): Flexible soft connections on the manifold lines of electrolytic/UV ballast water treatment units and ballast pumps to prevent stress on composite piping.
- Marine Desalination Plants: Critical anti-corrosive flexible links serving reverse osmosis (RO) high-pressure pumps and multi-stage flash distillation headers.
- Scrubber Washwater Systems (EGCS): Reliable rubber flexible joint installations on exhaust gas cleaning scrubber pumps dealing with highly acidic, corrosive seawater recycling loops.
FAQ
Q: Why is the combination of TA2 titanium flanges and CB/T 46-2007 compliance critical for this DN65 rubber expansion joint in marine systems?
A: Marine piping systems operating with raw seawater face simultaneous threats from severe mechanical stress and electrochemical destruction. Our engineered rubber expansion joint resolves these critical shipyard vulnerabilities through four technical pillars:
-
- Elimination of Galvanic & Velocity Pitting: Standard stainless steel flanges (even 316L) face severe pitting under stagnant seawater or high-velocity turbulent flow. By utilizing TA2 titanium flanges, the metal components form an instantaneous, permanent passive oxide layer, eliminating localized corrosion and ensuring zero metallic contamination across the rubber-to-metal boundary.
- Verified CCS Class Compliance: Shipyard procurement requires stringent class documentation. This rubber bellow conforms strictly to CB/T 46-2007 marine specifications and holds full CCS type approval, meaning it has passed rigorous bursting, vacuum, and displacement tests required for unconditional installation in commercial vessel engine rooms.
- Bespoke Soft-Connection Engineering: We recognize that standard 115mm lengths do not fit every legacy refit or modified hull layout. If your engineering team requires custom vacuum reinforcement rings, specific tie-rod limit assemblies, or custom flange drillings (JIS, ANSI, or DIN offsets), we provide comprehensive custom-to-drawing manufacturing tailored to your exact CAD files.
- Premium Quality with Compressed Lead Times: Waiting for specialized titanium marine components from conventional overseas suppliers often stalls shipyard schedules. We combine rigid premium quality control protocols with a highly responsive supply chain, delivering fully certified, high-end marine expansion joints within tight delivery windows to keep your fleet on schedule.
