Can be Customized Pipe Expansion Joint Flange Type PTFE Bellows

Can be Customized Pipe Expansion Joint Flange Type PTFE Bellows

Product Description

Addressing complex piping geometries and thermal transients, the PTFE bellows incorporates advanced kinematic design principles. Its three-dimensional flexibility—permitting axial compression/extension, lateral offset, and torsional rotation—mitigates stress concentrations caused by building settlement, thermal cycling, or seismic activity. PTFE bellows core's low friction coefficient (μ < 0.1) facilitates smooth bending without energy loss, while the metallic reinforcement layer prevents over-extension and kink resistance. Tested to exceed 10,000 cycle durability in fatigue testing, this component minimizes maintenance requirements in marine exhaust systems, geothermal power plants, and nuclear reactor coolant loops. Optional FDA-compliant silicone-free liners are available for food-grade applications.

Performance characteristics

1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced Rubber Joint provides long-lasting performance.
3. Corrosion Resistance: Resists aggressive environments and chemicals.
4. Noise & Vibration Reduction: Dampens vibrations and shock waves.
5. Ease of Installation & Maintenance: Compact design and standard flange connections facilitate installation and upkeep.
