Description

PTFE-lined Viton (FKM) rubber expansion joint with carbon steel flange. Inner PTFE lining resists strong acids, alkali, and corrosive chemicals. Viton outer rubber layer provides high temperature & oil resistance. Absorbs pipeline vibration, noise, and multidirectional displacement, widely used for chemical corrosive medium piping. Custom sizes are supported.

Main Features 

1. Dual-layer structure: Inner PTFE lining, outer Viton(FKM) rubber body
2. Outstanding corrosion resistance against strong acid, alkali, solvent, and chemical media
3. Viton(FKM) rubber performs well in high-temperature, oil-resistant working conditions
4. Absorb axial, lateral, and angular displacement; dampen vibration and reduce pipeline noise
5. Carbon steel painted blue flange for easy bolt-on installation, good sealing performance
6. Prevent medium erosion to rubber body, extend service life in harsh chemical environment
7. Customizable: DN size, pressure rating, flange standard can follow customer requirements

Application 

1. Chemical & petrochemical industry 
2. Wastewater treatment plant 
3. Pharmaceutical processing pipeline 
4. Pickling & electroplating workshop 
5. Corrosive fluid transmission system
6. Paper-making industrial piping
