One of our company’s clients has a piece of equipment that needs to be sealed. We offer mechanical seals using metal bellows, but I’m not sure which material would be suitable. I would appreciate your advice on this matter. The fluid in question is liquid nitrogen; the temperature is -180 degrees Celsius, the rotation speed is 8400 RPM, and the pressure is 15 kg/cm2. Please give me some guidance.
