PTFE Bellows Expansion Joints

PTFE bellows expansion joints (PTFE corrugated compensators) are high-performance piping components engineered with a PTFE corrugated core and metal flange/end fittings, designed to absorb thermal expansion/contraction, vibration, and misalignment in corrosive fluid systems.

Core Advantages

Extreme Chemical Inertness: PTFE bellows resist nearly all acids, alkalis, solvents, and oxidants (except molten alkali metals/fluorine), ideal for harsh chemical processing.
Thermal & Mechanical Flexibility: Corrugated structure compensates for axial/lateral/angular movement (-200°C to 260°C operating temp), protecting rigid pipeline sections from stress.
Leak-Tight Sealing: Integrated metal flanges (stainless steel 304/316) ensure secure connections, with PTFE’s non-stick surface preventing media adhesion and clogging.
Low Friction & Purity: Smooth PTFE inner surface minimizes pressure loss and avoids medium contamination—suitable for high-purity pharmaceutical/electronic fluid transport.

Key Applications

Chemical processing (acid/alkali transfer), pharmaceutical production, semiconductor manufacturing, and wastewater treatment systems with corrosive media.whatsapp:+8613910195827
