mechanical sintered silicon carbide seal ring

mechanical sintered silicon carbide seal ring

Carbide mechanical seal rings are widely used in petroleum, chemicals, machinery and other pipesealing, like dry gas seals ,Oil film seals, Spring mechanical seal, High speed pumps.

With advanced molding technology, can produce a variety of complex shapes of carbide products; can be produced according to user's drawing.

Pressureless sintered silicon carbide (SSIC) is produced using very fine SiC powder containing sintering additives. It is processed using forming methods typical for other ceramics and sintered at 2,000 to 2,200° C in an inert gas atmosphere.As well as fine-grained versions, with grain sizes < 5 um, coarse-grained versions with grain sizes of up to 1.5 mm are available.

SSIC is distinguished by high strength that stays nearly constant up to very high temperatures (approximately 1,600° C), maintaining that strength over long periods!
