Product Description & Specifications

Product Overviewย 

Theย DN200*150 (210mm length) Concentric Reducer Custom Flexible Jointย is specifically engineered for the high-pressure, corrosive environments ofย Offshore Oil & Gas engineering. As a high-performanceย rubber expansion joint, it facilitates the seamless transition between differing pipe diameters while mitigating the intense vibrations of offshore pump stations.
We take pride in ourย Hand-Built (Hand-Layered)ย manufacturing process. By moving away from standardized molds, we offer aย 100% custom-to-drawingย service, allowing us to adjust reinforcement layers forย 16 Barย reliability and precision-match theย SS316 flanges to your specific platform standards (ANSI/JIS/DIN).

Key Featuresย 

  • Expert Customization:ย Every joint is built to your CAD drawings. We can customize the eccentric/concentric taper, the exact 210mm face-to-face length, and flange drilling.
  • Marine-Grade SS316 Flanges:ย Superior resistance to pitting and crevice corrosion in salt-heavy offshore atmospheres.
  • Hand-Built Safety Margin:ย Manual layering of high-tenacity fabric ensures structural integrity that surpasses mass-produced alternatives, especially under 16-bar cyclic loading.
  • EPDM Resilience:ย Premium EPDM elastomer provides long-term ozone and UV resistance, essential for open-deck offshore installations.
  • Optimized Flow Dynamics: The concentric design ensures a smooth fluid transition, reducing turbulence in critical cooling or fire-main systems.

Applicationsย 

  • FPSO & Jack-up Rigs:ย Main seawater cooling and ballast water transfer lines.
  • Offshore Fire-Fighting:ย High-pressure fire-main reducers requiring SS316 durability.
  • Coastal Desalination: Flexible links for high-salinity brine intake systems.

FAQ

Q: How does your “Custom-to-Drawing” capability benefit offshore piping engineers specifically?
A:ย Offshore engineering leaves zero room for “forced fit” installations. Ourย custom flexible joint service addresses this through:
  • Dimensional Accuracy:ย If your platform’s pipe gap is exactlyย 210mm, ourย hand-builtย process ensures the joint fits perfectly, preventing “initial stress” that often leads to premature failure in standardย rubber expansion joints.
  • Pressure Tailoring:ย Forย 16 Barย offshore systems, we don’t just use more rubber; we strategically layer the reinforcement plies according to your system’s surge pressure requirements specified in the technical drawings.
  • Material Traceability:ย We understand the compliance needs of marine projects. Every custom unit can be supplied withย SS316 material certificates (EN 10204 3.1) and individual pressure test reports to ensure it meets offshore safety standards.
