High temperature CF flange connection vacuum bellow hose

In vacuum technology,non-braided annularly corrugated hoses are typically used with standardised small CF flanges as quick-assembly vacuum hose assemblies for the connection of devices,pump,measuring equipment and test benches. 

Hydra annularly CF flange vacuum hose without plastic seals can be heated up to 450℃ and can therefore be used in ultra high temperature vacuum applications.If connections are used as small flanges, the vacuum bellow hose assemblies can be used at pressures down.If an external supporting ring is used in addition,then the vacuum CF flanges are used for inside over pressure up to approx. 1.5bar. 


Standard Specifications

 
Material
Hose SUS304, SUS316L
Tube end/Flange SUS304, SUS316L
Braid SUS304 or without Braid
Working PressureVacuum ~1.5Mpa ,vacuum~atmospheric pressure
Allowable Leak Rate1.33x10^10Pam3/sec or less

Vacuum Connection Type 
1. KF (NW) is applied in the vacuum system of the quick unloading flange, tube diameter is generally in 50mm (2 inches) or less, twist the wing nut simply by hand can be loosened or compressed for coupling.
2. CF is a flange connection for ultra-high vacuum, it’s metal static sealing, high sealing performance and low leakage rate, withstand high-temperature baking.
3. LF (ISO) connections that can be used from atmospheric pressure to high vacuum, often used in detachable applications. The tube diameter is generally more than 50mm (2 inches), ISO flange’s two common forms are ISO-K and ISO-F.


Vacuum Hose Features 
1. Vacuum hose tube is formed from strip welding, hydraulic forming, finished product assembly and leakage detect to ship.
2. Indicators of vacuum hose tube (Flexible Tube), can be produced according to customer’s indicator
3. Non-oxidation technology of welding, so it’s not need process of mechanical polishing, electrolytic polishing which harmful for quality.
4. Fully automatic welding assembly to ensure product quality stability.
5. The vacuum hose’s working temperature range -196 ~ +450 ℃
6. Helium leakage rate: 5 * 10-10Pa • m3 / s or less
7. Vacuum hose can be welded with KF, ISO, CF, VGF, GB and non-standard flanges.
8. Provide rigid hose with small shrinkage and excellent flexibility hose to meet customer needs.
9. Mainly applied in aerospace, aviation, shipbuilding, vacuum, electricity, gas and other industries.
