What are the precautions for welding vacuum bellows when ordering vacuum bellows? 1. First, 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. If non-standard flanges need to provide drawings. 2. The customer needs to explain the use environment and temperature, and the requirements for the leakage rate. As a manufacturer, we can choose the appropriate product to recommend to you, or if you have standard drawings, we can make and process according to the drawings. 3. The customer needs to explain the medium in the vacuum bellows (whether it is corrosive or not). There are differences in the material of the vacuum bellows. Generally speaking, stainless steel 316L is used for corrosiveness, and stainless steel 304 can be used for non-corrosiveness."
