Brief introduction:
Post Vacuum is a company specializing in the design and manufacturing of ultra-high vacuum parts. It mainly produces various high vacuum and ultra-high vacuum components. Vacuum parts.
Bellows can be used in ultra-high vacuum systems and can achieve bending, telescopic and eccentric functions
Bellows are usually divided into two types: formed bellows and welded bellows, which are used in ultra-high vacuum systems. The bellows material is generally stainless steel.
To make formed corrugated pipes, first roll the stainless steel plate into a cylinder shape and weld the joints. The cylinder is inserted into the corrugated pipe mold, and the production of the formed corrugated pipe is completed by hydraulic pressure.
In ultra-high vacuum systems, the bellows connecting the high vacuum pump and the backing pump mostly uses formed bellows with flanges at both ends.
The advantages of formed corrugated pipes are simple production and low cost. The disadvantage is lack of stretch and flexibility. What makes up for the shortcomings of formed bellows is welded bellows.
Welded bellows is a thin-walled corrugated hose formed by alternately welding circular stainless steel sheets with inner and outer diameters. The welding method is plasma welding. This kind of bellows has great flexibility and is an indispensable component in the connection of ultra-high vacuum systems and various motion introducers. Reasonable selection of the natural length of the corrugated pipe can provide a service life of more than hundreds of thousands of times.
Various series of complete bellows are manufactured for most industrial applications. It can be used in a variety of installation and connection places to achieve flexible connection. The connection and transition between fixtures becomes easier and easier.

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
