PTFE-lined Viton (FKM) rubber expansion joints with carbon steel flanges are designed for demanding chemical and industrial piping applications. The inner PTFE lining provides excellent resistance against strong acids, alkalis, solvents, and corrosive chemicals, while the outer Viton (FKM) rubber layer offers superior high-temperature and oil resistance. This advanced composite structure effectively absorbs pipeline vibration, reduces noise, and compensates for axial, lateral, and angular displacement. Customized sizes, pressure ratings, and flange standards are available to meet different engineering requirements.
Main Features
1. Dual-layer construction with an inner PTFE lining and outer Viton (FKM) rubber body for enhanced protection and durability.
2. Excellent corrosion resistance against aggressive chemicals, strong acids, alkalis, solvents, and corrosive media.
3. Viton (FKM) rubber provides outstanding performance under high-temperature and oil-resistant operating conditions.
4. Effectively absorbs axial, lateral, and angular movements while reducing vibration and pipeline noise.
5. Carbon steel flanges with a painted blue coating provide convenient bolt-on installation and reliable sealing performance.
6. PTFE lining prevents corrosive media from contacting the rubber body, extending service life in harsh chemical environments.
7. Fully customizable options including DN size, pressure rating, flange standard, and other specifications according to customer requirements.
