PTFE Expansion High Pressure Resistant Rubber Flexible Joint Bellow
In Piping Customized
Product Description
For industries demanding contamination-free fluid transfer, the
PTFE Flexible Joint Pipe sets new benchmarks in purity and
reliability. The seamless PTFE liner undergoes ultra-high molecular
weight processing to eliminate porosity, ensuring compatibility
with ultra-pure water (UPW), photoresists, and corrosive gases.
Reinforced with AISI 316L stainless steel or Hastelloy® alloy
braiding, the assembly withstands pressures exceeding 40 bar while
maintaining burst strengths up to 160 bar. This dual-layer
architecture provides exceptional flexibility in cryogenic
applications down to -200°C, making it suitable for LNG transfer,
pharmaceutical cryogenic storage, and aerospace fuel systems. The
patented convoluted bellows design further enhances vibration
damping capabilities, critical for reducing particle generation in
semiconductor fabs.
Performance characteristics
1. Flexibility: Accommodates axial, lateral, and angular movements.
2. Durability: Reinforced rubber flexible 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.
