Features
Unique protection against chemical, corrosion and high temperatures • Low spring rates for axial, lateral and angular movements to protect stress sensitive equipment al elevated temperatures. • High or low temperature performance • Absorption of large movements with short overall length due to high flexibility.
Temperature-Pressure
Teflon expansion joints withstand temperatures as high as 230’C and as low as -70’C. Temperatures of the system affect the pressure rating of the expansion Joints. For vacuum service, anti-vacuum rings made of stainless steel and encapsulated with PFA tube are put inside the convolution.
