What is the lifespan of flexible teflon tubing under continuous use?

 The lifespan of flexible Teflon (PTFE) tubing under continuous use can vary based on several factors, but it typically ranges from 5 to 10 years or more. 

Here are some key factors that influence its lifespan:

Factors Influencing Lifespan

  1. Temperature and Pressure Conditions

    • PTFE tubing can withstand a wide temperature range (-200°C to +260°C) and varying pressures. Operating near the extreme limits of these ranges can reduce its lifespan.
  2. Chemical Exposure

    • While PTFE is highly resistant to most chemicals, prolonged exposure to aggressive substances, especially at elevated temperatures, can lead to degradation over time.
  3. Mechanical Stress

    • Continuous bending, flexing, or movement can cause wear. The design of the application (e.g., tight bends or high flex cycles) may affect longevity.
  4. Installation and Handling

    • Proper installation and handling are critical. Kinks or sharp bends during installation can compromise the integrity of the tubing.
  5. Quality of the Tubing

    • The manufacturing quality and grade of the PTFE tubing also play a significant role. Higher-quality tubing may have additives that enhance durability and performance.

Summary

Under optimal conditions, flexible Teflon tubing can last 5 to 10 years or longer with continuous use. To maximize its lifespan, it's essential to consider the operating conditions and application requirements, ensuring they align with the tubing's specifications. Regular inspection can also help identify any signs of wear or degradation early.
