Flanged metal flexible hoses, also known as stainless steel corrugated flexible pipe connections, consist of stainless steel corrugated pipes, steel wire braided mesh, and end fittings. They feature flexible bending, vibration damping and noise reduction, high pressure and high temperature resistance, and corrosion resistance, making them specialized pipe fittings for pipeline compensation, vibration reduction, and handling corrosive media.
1. Inner Corrugated Hose: 304/316 stainless steel, can bend and stretch freely
2. Steel Wire Braid: Double-layer steel wire wrap, enhancing pressure resistance and explosion prevention
3. End Fittings: Flange type, threaded type, grooved type, welding type
4. Sealing Gasket: High-temperature resistant rubber/PTFE gasket, sealing to prevent leakage
Relying on the flexibility of stainless steel corrugation to absorb pipeline thermal expansion and contraction displacement
Reducing vibration of pump equipment, preventing vibration from transmitting along the entire pipeline
Compensating for pipeline installation misalignment and foundation settlement deviations
Corrosion and high-temperature resistant, transporting special media without corrosion or damage
1. High-temperature and high-pressure resistant, suitable for steam and high-temperature hot water
2. Acid and alkali resistant, corrosion resistant, suitable for chemical wastewater media
3. Strong flexibility, can bend freely, easy to install
4. Good vibration and noise reduction effect
5. Anti-aging, long service life
6. Tight sealing, not easy to leak water or air
1. Vibration damping for pump room pump inlets and outlets
2. High-temperature thermal steam and heating pipelines
3. Firefighting water supply and drainage projects
4. Chemical corrosive media pipelines
5. Mechanical equipment inlet and outlet connections
6. Pipeline settlement and displacement compensation positions
