EGC’s Engineers worked with a manufacturer that was dealing with a system that exhibited temperatures as high as 1,600 degrees Fahrenheit. While graphite is considered a high-temperature fluid sealing material, this particular situation required EGC’s engineers to experiment with ways to handle the heat.

The Engineers started by reviewing the application, which involved processing soot in a way that pushed hot gas through the system to rid the atmosphere of harmful emissions; thereby causing temperatures in the whole system to increase to as high as 1,600 degrees F. At those temperatures, traditional flexible graphite is no longer suitable.

The Engineers at EGC developed a seal that contained a combination of ceramic, silica, vermiculite and other high-temp materials including metal. A fibrous material, a very tight filter of sorts, was added to provide obstruction to the flow of particles. The cavity itself had to expand or contract due to temperature swings while in service. EGC’s Engineers had been looking at 0.040” in a linear format and 2 degrees angular. They tested the newly engineered material to simulate actual field conditions both at EGC and the manufacturing facility. The result was a seal that did exactly what it was intended to do!

With a non-graphite material, the seal fiber is rated at 2,300 degrees F and stood up to extreme temperatures. As particulates from the emissions built up in the seal, it acted like a blocking agent and increased its seal-ability.
