The gaskets used for centrifugal ductile iron pipes are T-type sealing gaskets, which are the standard gaskets for the installation of ductile iron pipes.
Requirements for the rubber sealing ring assembly are as follows:
1. Rubber seals should maintain excellent sealing performance within the working pressure and a certain temperature range, and automatically enhance their sealing effectiveness with increasing pressure.
2. The friction between the rubber seal ring assembly and the moving parts should be minimal, and the coefficient of friction should be stable.
3. Rubber seals have strong corrosion resistance, are not prone to aging, offer a long service life, and possess good wear resistance, capable of auto-compensating to some extent after wear.
4. Simple structure, easy to use and maintain, extending the lifespan of rubber seals.
