What are the advantages of metal seals compared to traditional ones?

The metal hollow O-ring, as its name implies, is a metal hollow circle, which is a kind of gasket. Its application field is very wide, and it has more advantages compared with the traditional metal closed ring. It is in the traditional metal closed ring The above is improved and perfected, so it is deeply loved by consumers. In addition, what are the advantages and disadvantages of metal hollow O-rings compared with traditional metal sealing rings?

The comparison of metal hollow O-rings and traditional gaskets is relative to traditional seals, such as aramid fiber rubber gaskets (non-asbestos gaskets), rubber gaskets, PTFE gaskets, rubber O-rings, and metal hollow O-rings. The advantage is temperature resistance, even if the ordinary 316L or 321 material, it can continue to withstand high temperatures above 450 degrees, if special alloy materials are used, it can work at 700 degrees for a long time, and the seal structure can be changed to adapt to higher temperatures. Working conditions.
　　
Compared with the traditional solid copper gasket and solid stainless steel gasket, the metal hollow O-ring only needs a small load to achieve a considerable sealing effect. In addition, the metal hollow O-ring has high resilience characteristics, which is also Solid metal sealing ring can not be compared.
　　
Compared with metal spiral wound gaskets and metal coated gaskets, metal hollow O-rings have high pressure resistance, low leakage rate and product reliability, and the cleanliness required by special materials are also spiral wound gaskets and coated gaskets. What the film doesn't have.
　　
In summary, the metal hollow seal ring is indeed a good product.
