Problems with Type C and D flanges
Thread Content
Everyone: How much do you know about Type C and Type D flanges, and what are their respective functions? I hope those with more experience can share their opinions and insights. It would be best to include illustrations, so that everyone can understand it more thoroughly. I hope the moderators can rate those who leave comments
Type C, D flanges? Seems I haven’t heard of it
The raised and recessed face flanges are classified into types A, B, C, and D; information can be found in the book \"Steel Pipe Flanges, Gaskets, and Fasteners\".
Sir upstairs: I’m not sure which specific sections of HG20592 you are referring to. It would be even better if there were illustrations along with the text; that might arouse greater interest among people to get involved
Flanges corresponding to A, B, C, and D type metal wound gaskets: Flanges are generally classified into raised face, flat face, male and female face, tongue and groove flanges, and grooved flanges. Type A metal wound gaskets are suitable for male and female face flanges, tongue and groove flanges, and grooved flanges. Type B metal wound gaskets are suitable for male and female face flanges. Type C metal wound gaskets are suitable for raised face flanges as well as flat face flanges. Type D metal wound gaskets are suitable for flat face flanges and raised face flanges. Metal wound gaskets provide multiple layers of sealing, are resistant to high temperatures and corrosion; once compressed, they can adapt to the irregularities of the sealing surfaces, filling any gaps there and ensuring good sealing performance even under changing system temperatures and pressures. Does not soften or creep at high temperatures ； It does not harden or shrink at low temperatures. It is not blown out at high pressure.
