What is the maximum operating pressure achievable for internal plate-fin heat exchangers in cold storage units in China at present? Please ask an expert to answer.
Waiting for a response; normally it’s 45 kilograms.
Reply to 1# yfq4308: I can give you a definite answer. There is a company specialized in cold boxes that has come to our institution for promotion (the company name will not be mentioned); they claim to be able to handle up to 130 kilograms. Of course, it’s not clear whether there are any applications available domestically. However, they are foreign companies with a long history of manufacturing, and I personally find them to be reliable. However, they also say that applications are generally not that large, usually under 100 kilograms. I hope this can help you.
Yes, it seems to be used in hydrogenation or certain special chemical syntheses
In China, those made of aluminum alloy currently face difficulties in reaching 8 MPa; only smaller-sized ones can achieve this. Abroad, stainless steel plates can be used; pressures of over 10 MPa are no problem. At present, it is not yet possible in China to manufacture cold boxes made of stainless steel
