Sealing issues in tube-and-sheet heat exchangers
Thread Content
In the design of U-tube sheet heat exchangers, can \"O\" rings be used as gasket materials at the tube sheet? During the production process, repeated disassembly and assembly may be required. If wound gaskets are used, they are generally discarded after just one use, and they require high standards for assembly. On the other hand, \"O\"-rings not only provide reliable sealing but can also be reused, thereby reducing the difficulty of assembly. Of course, the operating temperature of “O” definitely needs to be taken into consideration.
“It features an O-ring seal; the gasket tends to get stuck in the sealing groove, making it difficult to remove, and it is essentially ruined after just one disassembly.
It’s best to respect the original design; even O-rings come with many considerations, as well as differences in materials.
The operating pressure also matters; an \"O\" ring cannot be used at high pressures.
Pressure, medium, temperature, bolt strength – consider everything!
Normal heat exchangers aren’t disassembled and reassembled frequently, right? For O-rings, factors such as the temperature of the medium and its chemical properties need to be taken into account; they seem less reliable than gasketing materials. Moreover, large O-rings are difficult to manufacture, and their soft nature makes installation more challenging.
When removing it, the O-ring does not get stuck in the groove, making it easy to take out. I mainly want to know if it can be used and whether there are any standard regulations
We are the manufacturer, so the material of the O-ring is definitely something we take into consideration.
At what high pressure cannot it be used? Which standard specifies this clearly? I want to use an O-ring as a seal now, but I can’t find any basis for this; please advise
