Due to their strong chemical resistance, PTFE expansion joints are very suitable for absorbing thermal expansions in applications with corrosive media.
The bellows of the PTFE expansion joints consist of several waves. The standard versions consist of 2, 3 or 5 waves, but other designs are also possible. Externally, the bellows are reinforced by stainless steel reinforcement rings and on both sides the bellows are fitted with loose-fitting flanges in steel or stainless steel. The flanges have tapped holes drilled according to EN or ASME. The compensators are also equipped with tie rods in steel or stainless steel.
In addition to the standard compensators, there are also compensators with bellows in Extra Heavy Duty and anti-static versions with black PTFE instead of the standard white PTFE. Versions with coating of the flanges, anti-snaking flange, hinges, vacuum support ring and other designs are also possible by appointment
