Specifications and quality requirements for metal wound gaskets
Thread Content
Where can I find the specifications and quality requirements for metal wound gaskets? For the wound gaskets we use on site, there is no graphite in the outer part of the steel strip; are there any regulatory requirements regarding this? What are the acceptable coverage requirements for the area where the steel strip is wound in graphite-metal wound gaskets? In my opinion, the steel strip winding part of the metal wound gasket should be completely covered with graphite; there should be no uncovered areas. . .
Take a look at \"JBT 6369-2005 Technical Requirements for Flexible Graphite Metal-Wound Gaskets\" and \"NBT 47025-2012 Wound Gaskets\"
Even when both are in use, normal operation still results in graphite seeping into the gaps between the metal winding strips
