32 custom designed VSG or VSG Pro pressure seals, shipped in a single day? Been there, done that.
When it comes to shipping the same old off-the-shelf graphite pressure seals, day-after-day, 32 is a pretty insignificant number. But, when you have to custom engineer every single one of those 32 seals AND they must be shipped on the same day, that’s a compelling achievement.
It happened on March 20, 2019. “We had multiple aftermarket customers who had to replace pressure seals and packings for outages at the same time,” said Rob Garlock, engineer for the custom designed graphite pressure seals. “Some of the pressure seals were small measuring just 6” in diameter. Others were as large as 18”. Regardless, every pressure seal takes the same time to custom design to fit the application, but luckily EGC has the engineering staff to support this type workload. It definitely wasn’t easy”
“The condition of a valve in a power plant changes as it moves from a brand-new installation to when it’s time to be repaired,” says Rob. “Among other things, the valve may be steam cut, have pitted surfaces, could be oversized or even out-of-round. So, at EGC, we must look at the valve as it is right now, not as it was when it was brand new.”
According to Stu Padgett, Corporate Purchasing for Industrial Valve in Mobile Alabama and an EGC customer, “They’ve all got to be dead-tight! We’ve got to have a 100% seal on every one of them. The problem is that you’re using a VSG graphite seal in a valve that could be 50 years old. Any part you put in there may be less than perfect. But the flexibility of graphite is so forgiving that you don’t need perfect parts to get a 100% seal. They seal every time.”
The high-density VSG Graphite pressure seal is resilient, so it guards against high cycling. It’s a direct replacement for metal seals and won’t fuse to valve components. In time studies, you can save nearly 75% of your time installing graphite over metal. It works in out-of-round, oversize, steam-cut and pitted bonnet cavities. And, its custom engineered for each individual application. Best of all, it’s delivered in 48 hours. Same day, if necessary!
That’s exactly what EGC did on March 20. And they did it 32 times.
