PTFE Spring-Energized Cryogenic Seals Revisited

Cryogenic Seals

Cryogenic seals must not only handle unbelievable low temperatures, but also perform under highPTFE-spring-energized-cryogenic-seals.png pressure conditions.  If you aren’t familiar with cryogenic seals, a cryogenic seal is a special type polymer seal used with media at temperatures below -238°F and down to -460°F (absolute zero).  Cryogenic seals can be found in a variety of industries, from LNG compressors and loading arms in the petroleum industry to rocket propulsion systems in the aerospace industry.

Polymeric Seals for Wind Turbines in Rigorous Conditions

Wind Turbine Seal Challenge

Because of the wide variation in where wind turbines are located, seals are expected to operate under temperatures between -40°F in the Artic to 140°F as a maximum standard operating temperature.  Wind turbines are exposed to UV and ozone, vibration, and high stresses.  Wind turbine parts are expected to last for twenty years – a considerable challenge for such rigorous conditions, but a challenge that is being met.  One area where these issues are being addressed is in the design and retrofitting of seals.
