SS304 KF(NW) flange clean vacuum hose
Size DN6(1/4”)- DN300(12”)
The vacuum technology is widely used in the semiconductor, LCD , LED, space development, accelerator and food industries and is one of the indispensable technologies in these days. Our SS304 KF flange vacuum hose is based on this principle. The KF flange vacuum hoses for vacuum use are manufactured in a clean environment so that vacuum hose can be used in these vacuum technology fields. You can be reassured to buy and use our clean vacuum hoses.
SS304 flange vacuum hose is used for a variety of high vacuum and ultra-high vacuum environment in pipeline, with characteristic of flex corrugated pipe wall to absorb pipe's specific displacement ,KF flange vacuum hose which cohesion vacuum pump can also slow down the vibration affected generated by the equipment when vacuum pump in working. The vacuum hoses also have many other advantages, like flexibility, thermostability, anti-corrosion and so on. Daming provide two type vacuum bellows, one is the flexible but can't be compressed, and the other one is flexible and also compressible. You can choose one vacuum hose which is suitable for you. Both ends of the flanges can be welded standard KF, ISO, CF etc and non-standard ones. NW vacuum hose is widely used in a variety of industrial devices, such as semiconductors, radio and television, solar industry and other equipment. And the products which have same function are stainless steel SS304,SS316L,SS321 vacuum hose, flexible hose for vacuum, flexible pvc vacuum hose and so on, you can click and select them.

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.
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 indicators
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.
Application
· Vacuum pump vibration absorption
· Absorb displacement and installation of hard pipe
· Pipeline which can not be installed in rigid pipe system
· Research and development, samples of temporary piping system components,
· Add braids outside to produce high-pressure metal flexible hose
