The vacuum flange is the flange on the tube end, which is used to connect the vacuum chamber, the pipeline and the vacuum pump to each other. Vacuum flanges are used in scientific and industrial applications to allow various devices to interact through physical connections, as well as vacuum maintenance, monitoring and operation from outside the vacuum chamber.
This is a pair of smart sealing assembly for tube vacuum furnace to tighten both ends of OD 3.5" (88 mm - 90 mm ) tube without any welding and gluing.
Factory supply, size can be customized according to customer requirements, if you need more details, please feel free to contact us.
Technical Parameters
| Made of Stainless Steel with double high-temperature silicone O-rings on the flange. Stainless steel needle valve with 1/4" pipe adaptor. The assembly kit will seal one end of 89-91 mm ( 3.5") diameter ceramic and quartz tube. Vacuum meter is installed in one side of flange. You may choose left side, right side or a full set of the flange at product option bar Note: You may order Digital Temperature Controlled Recirculating Water Chiller with 16L / min Flow, to cool the flange and save water. |
Vacuum Level | 10E-2 torr by a mechanical pump 10E-4 torr by a small turbopump and 10-6 torr by hi-speed turbopump |
Warming | Must put a refractory tube block between the flange and the sample to avoid melting the silicone O-ring by heat radiation. Please order a ceramic block in related products. Please do not over tighten the three hex screws on the flanges to avoid overpressure incidents. The recommended torque is 35~40 inch-lbs. For liability considerations, our company does not recommend or endorse the use of any toxic, flammable or corrosive gases with our flange assemblies. Please contact us with any concerns. |
| Max. furnace working temperature is 1100ºC without thermal block if tube furnace is installed with this water cold flange If furnace working temperature > 1100ºC , suggest you use a quartz thermal block . Please always use recirculating water chiller to save water and protect |
Related | Please contact the manufacturer to choose 1" to 12" flange according to your own requirements |
