What is the maximum temperature that a lined tower in China can withstand?
Thread Content
The company’s new project requires the use of a wash tower; the process involves materials that are weakly acidic or alkaline and contain solid resin particles. The operating pressure is 2 BAR, and the operating temperature is 95°C. Design pressure: 4 BAR, design temperature: 120°C. Previously, since the temperature was only 80 degrees, rubber-lined towers were always used. Is there still a suitable rubber-lined tower available for this operating condition? It is said that Sigri and the prince are nice people; does everyone know that? Also, if the rubber lining is not suitable, are there any other recommendations? :handshake
I didn’t understand; there are some issues with the way you expressed it!
It depends on the material used as the lining; for example, PTFE can withstand temperatures of 120 degrees.
Could you say something a bit more detailed?
So what kind of rubber do you use? There are many types of rubber! What kinds of media are there in your devices? Is there negative pressure?
For this, PTFE lining is generally the only option; as far as I know, rubber linings have not yet reached such a high standard.
I’m sorry, maybe I didn’t explain myself clearly. The rubber-lined towers we used before had an operating temperature of 80 degrees, with a design temperature of 90 degrees; therefore, butyl rubber was used for lining them. The temperature requirements for the equipment in use now have been significantly increased; the operating temperature must reach 95 degrees, with a design temperature of 120 degrees, under positive pressure. So now I’m struggling to find the right material. After checking, it is said that Sigri and Prince Jingjiang are the best. One is German technology, and the other is Japanese technology. And both of these companies promise to be able to reach a temperature of 120 degrees. But I’m still a bit worried, so I’d like to consult the experts here to make sure that it won’t break after just one year of use. Thank you all! :The specific operating conditions for handshake are:
The temperature is too high; using rubber-lined materials won’t work; under the conditions mentioned by the original poster, PTFE materials are the only option.
Thank you all. It seems I can only choose one lined with PTFE. But both of their companies told me that they could guarantee it, giving as an example equipment they use in some power plants that is designed to operate at a continuous temperature of 95 degrees. I wonder if the experts know?
Titanium lining is a one-time solution that offers excellent corrosion resistance, but it’s expensive!
120 degrees exceeds the operating temperature range for butyl rubber, but EPDM should be able to meet your application requirements; its operating temperature range is from –60 to +150°C.
