The superiority of metal spiral wound gaskets for mechanical seals

　2016-12-29　　

Metal spiral wound gaskets are used for mechanical seals—expanded graphite spiral wound gaskets not only have the advantages of asbestos spiral wound gaskets. And it avoids the aging of asbestos due to the removal of crystal water under high temperature, which has the disadvantage of 'capillary' appearance and lead to leakage. Moreover, the 'capillary fibers' of asbestos penetrate into the human respiratory tract, which is extremely harmful to the human body. At present, my country not only has expanded graphite wound gaskets of tinplate, low carbon steel, and stainless steel, but also developed gaskets wound with expanded graphite and polytetrachloroethylene in titanium, Monel alloy, etc. Sealing problem. Recently, pure expanded graphite wound gaskets have appeared, which have better performance than metal wound gaskets, and are simple in structure, easy to produce, and low in cost.　　218.html,
