PUSTVAC Vacuum CF Zero Length Reducing Flange

<>: >Vacuum zero-length variable diameter flange
Brand:
Brief introduction:
Post Vacuum is a company specializing in the design and manufacturing of ultra-high vacuum parts. It mainly produces various high-pressure vacuum parts. Vacuum and ultra-high vacuum components.
The flange is composed of two symmetrical knife-edge flanges connected by bolts and nuts.
Flanges are available in two forms: threaded hole flange and through-hole flange. Threaded hole flange can be selected, or metric thread.
In order to facilitate installation, flanges are divided into fixed flanges and rotating loop flanges. For installation locations with required installation angles, rotating loop flanges can be selected.
Threaded flanges usually have a through hole on one flange, and the other supporting flange is threaded. Stainless steel bolts pass through the through hole flange and are locked on the threaded flange. No nuts required
Through-hole flanges are fixed to each other through stainless steel bolts and nuts or steel plate nuts. The center of the steel plate nut is in the middle of two adjacent holes, which can replace the external hex head nut.

Product vacuum packaging
Branded vacuum products are vacuum packaged after vacuum degassing is completed.
Vacuum zero-length reduction installation and assembly diagram
b It is recommended to use high-quality high-temperature thread lubricant on all flange threaded fasteners (to avoid trouble caused by fastener slippage).
bWhen operating and installing components, it is recommended to use dust-free gloves for assembly. Because even the slightest fingerprint or other stain can greatly affect the vacuum's performance.
b Carefully check the smoothness or roughness of each flange sealing surface and sealing gasket surface before installation.
b Make sure the sealing gasket and the flange surface are parallel, align the leakage test grooves of the mating flanges, and then install the bolts and tighten them
b Tighten the bolts in clockwise or counterclockwise direction. Use the appropriate torque value to tighten each bolt one turn at a time until the mating flange surface is in contact
b. The torque value for tightening the bolts is listed in the table below
