Flanged bellow expansion joint lined with PTFE is a pipeline connection component with special structure and performance.
1, Structural characteristics
Flange type corrugated pipes are usually composed of a metal corrugated pipe body and flanges at both ends. PTFE lining is a layer of PTFE material tightly adhered to the inner wall of a metal corrugated pipe. PTFE has a smooth surface, which can reduce fluid flow resistance and effectively prevent direct contact between metal bellows and the conveying medium, thus avoiding metal corrosion.
2, Performance advantages
1. Strong corrosion resistance: PTFE has excellent resistance to most chemicals, whether it is acid, alkali, salt solution or organic solvent, it is difficult to corrode it, which makes PTFE lining flange corrugated pipes suitable for use in harsh chemical environments.
2. High and low temperature resistance: PTFE can be used for a long time in the temperature range of -200 ºC to+260 ºC, ensuring stable operation of the pipeline system under different temperature conditions.
3. Good sealing performance: The metal corrugated pipe itself has a certain degree of elasticity and flexibility, coupled with the smooth surface of the PTFE lining, which can provide good sealing performance and effectively prevent leakage.
4. Excellent wear resistance: The low friction coefficient of PTFE material gives it excellent wear resistance, extending the service life of the corrugated pipe.
3, Application Fields
1. Chemical industry: used for transporting various corrosive chemical media, such as strong acids, strong bases, organic solvents, etc.
2. Petrochemical industry: In refining and petrochemical facilities, it can be used as a connecting pipeline to adapt to complex process conditions.
3. Pharmaceutical industry: Meet the strict requirements for hygiene and corrosion resistance in the drug production process.
4. Environmental engineering: used for treating wastewater, exhaust gas, etc. containing corrosive substances.
