Classification of shell-and-tube heat exchangers
Thread Content
I have a shell-and-tube heat exchanger in the synthesis section of an ammonia synthesis system, which is commonly referred to as the synthesis cooling coil. The high-pressure section header is φ273*40, with L=7400. The branch pipe is φ85*15, L=8000, and the sleeve is φ159*5, L=7800. The pressure in the high-pressure section is 31.4 MPa. This type of heat exchanger was not previously classified; it was classified as Category I under the 2009 regulations, and no inspection is required. According to the rules of version 16 with large capacity, it should be classified as Category III A1. I would like to ask the experts: how do you classify similar shell-and-tube heat exchangers at present?
It can only be classified according to the rules of version 16 with a large capacity.
Just here to hang out; I’ll take a look and see what the conclusions are
