The vacuum bellows refers to a tubular elastic sensor connected by a foldable wrinkle sheet in the direction of folding and expanding. The main use of vacuum bellows is as a measuring element of a pressure measuring instrument, which converts pressure into displacement or force. What do we generally need to pay attention to when ordering vacuum bellows?
Notes for ordering vacuum bellows:
- First of all, the customer must clarify the connection method at both ends, generally including KF vacuum flange, ISO vacuum flange, CF vacuum flange, GB vacuum flange and non-standard vacuum flange, etc. For non-standard flanges, drawings are required.
- The customer needs to explain the environment and temperature used, and the leakage rate requirements. As a manufacturer, we can choose the most suitable product to recommend to you, or if you have standard drawings, we can make and process according to the drawings.
- The customer needs to explain the medium inside the vacuum bellows (whether it is corrosive). There is a difference in the material of the vacuum bellows. Generally speaking, stainless steel 316L is used for corrosion, and stainless steel 304 is used for non-corrosion.
