Seal Ring Carbon PTFE for Subsea Applications

Seal Rings - Carbon Filled

At WKH Group, we take pride in delivering the highest quality parts and components tailored to the requirements of our customers in a diverse range of industries. Recently, we manufactured seal rings made from Carbon PTFE for a customer in the subsea sector. 

What Our Client Required

The subsea sector demands materials that can withstand extreme underwater conditions, including high pressure, temperature variations, and corrosive elements. Our customer needed robust and reliable seal rings with superior sealing properties to prevent leaks and ensure equipment integrity which is why they chose carbon-filled PTFE.

 

Why Carbon-Filled PTFE?

  1. Enhanced Mechanical Properties: Carbon fillers improve PTFE's compressive strength, wear resistance, and load-bearing capacity.
  2. Improved Thermal Conductivity: Better thermal management, crucial for subsea applications.
  3. Chemical Resistance: Maintains PTFE’s resistance to chemicals, oils, and corrosive substances.
  4. Dimensional Stability: Ensures the seal rings maintain their shape under high pressure.
  5. Low Friction and Wear Resistance: Results in longer-lasting seal rings with minimal maintenance.

 

Our Manufacturing Process

We utilised advanced CNC (Computer Numerical Control) routing machines for manufacturing. The process began with using CAD software optimised to the drawings of our customer, followed by testing to ensure it was set up correctly.

The material was loaded onto CNC machines, which precisely shaped it into the desired seal ring geometry. Each seal ring underwent rigorous quality control, including:

  • Dimensional inspection
  • Surface finish evaluation
  • Performance testing

After passing these checks, the seal rings were deburred, polished, and prepared for shipment. CNC routing machines offer several advantages, including:

  • Precision and Accuracy: Achieving tight tolerances.
  • Consistency: Producing identical high-standard parts.
  • Efficiency: Faster production times.
  • Flexibility: Quickly reprogramming for different parts or design adjustments.

 

Final Applications

Leveraging the properties of carbon-filled PTFE and the precision of CNC routing, we delivered components that meet the rigorous demands of subsea applications. Our customised solutions, backed by engineering expertise and advanced manufacturing, ensure enhanced performance and reliability for our customers.

We continuously invest in research, technology, and process improvements to remain a leading provider of high-performance components for all environments including the most extreme ones. At WKH, no project is too big, too small, or too complex. For any precision engineering needs, simply call us on 0113 239 1909, email us at enquiries@wkhgroup.co.uk, or request a quote.
