PTFE Lined Flexible Expansion Joint axial bellows expansion flexible compensator for pipe
A: PTFE lined expansion joints combine the properties of metal and PTFE into the most advanced expansion joint available for highly corrosive piping systems.Our expansion joints are made of contour moulded PTFE, providing exceptional corrosion resistance and flex-life. The flexible liner is moulded over the metallic sealing face which eliminates troublesome separate gaskets and reduces the chances of bacteria build up. Different numbers of convolutions accommodate varying degrees of misalignment, axial travel and angular deflection between components.
Features
1. Excellent chemical resistance
2. High and low temperature resistance(-100°C to 260°C)
3. High pressure resistance
4. Anti-aging,long life without an aging problem
5. Wear resistance, high lubrication
6. Anti-corrosion ,non-stick, easily cleaned
7. Fire resistance
8. Electrically insulated
9. Excellent flexibility
Structure
Inside: PTFE hose, the hose can be smoothbore PTFE , and also convoluted , for high and low temperature used, anti-corrosive, non-stick.
Outside: Stainless steel braided. High pressure resistance. All kinds of couplings can be available.
