A non-asbestos gasket
Thread Content
What kind of gasket is it that consists of reinforced synthetic fibers bonded with NBR sheets (non-asbestos)? Is it similar to a covering pad?
Regarding NBR materials, according to the wiki, nitrile butadiene rubber (NBR) is a synthetic rubber that is a copolymer of acrylonitrile and butadiene, and it possesses excellent oil resistance. Commercial production was first initiated in Germany. http://en.wikipedia.org/wiki/Nitrile_rubber
Reinforced synthetic fibers bound with NBR sheets Note: pause here
It might be a “nitrile rubber pad”.
Reinforced synthetic fibers: enhanced synthetic fibers; bound with: literally means to tie or attach. NBR sheets: thin sheets of NBR. In my understanding, the core of this material is the enhanced synthetic fibers, while the outer layer consists of NBR sheets. I’m not sure if this is correct; it’s the first time I’ve seen this type of gasket. I appreciate it if everyone can share their opinions on this. Thank you very much.
Enhanced synthetic fiber pad made of extruded nitrile rubber (non-asbestos type) --------------------------------FYI--------------------------------
Reinforced synthetic fiber pads made of extruded nitrile rubber (non-asbestos type): I agree quite a bit with what was said above, but I’m not sure which standard specifies this
Your continuous interest has sparked my desire to learn more; therefore, I entered “gasket design manual” in Gudog and found the book titled “Practical Manual for Sealing Gaskets Used in Flanges”. The download address is: http://bbs.hcbbs.com/viewthread.php?tid=116932. By checking the table of contents, I found information on PTFE-coated gaskets (located on page 8 of the PDF file). If one does not think deeply about it, then by simply changing the word order of the answer for Y, it can be expressed as: Nitrile rubber-coated reinforced synthetic fiber pad (non-asbestos type). I am not competent enough to go any further in my answers. I hope informed individuals will continue to discuss this.
