Tetrafluoroethylene wound gasket
Thread Content
Recently, a new batch of gaskets arrived at the warehouse, and things were finally clarified. This gasket is made of stainless steel as its core material; it is coated with PTFE on the outside, and then wrapped in layers. I’m not sure about the performance of this gasket; please discuss it. What is the maximum temperature it can withstand, is it resistant to corrosion, and what is the operating pressure?
It can withstand temperatures up to 300 degrees, is resistant to corrosion, and has a pressure resistance of at least 10 MPa – this is what I’ve seen
This type of gasket is indeed better than ordinary ones
I used this type of gasket when creating pipe section lists; it is resistant to high temperatures and pressures, and very useful.
It is useful, but it is a bit expensive! If the process requirements demand it, it’s worth it!
Isn’t this the legendary PTFE-lined metal wound gasket? Generally, the pressure rating is 16 kilograms or 25 kilograms; it is corrosion-resistant, and can withstand temperatures up to 300 degrees. The sealing performance is excellent, though the price is a bit high – DN25 units cost several dozen yuan each.
