Re: Diesel corrosion

Again, quite interesting, Zane. Some years ago, I had an opportunity to do autopsies on about 100 dispensers - pumps, valves, and filters. Although I observed some internal surface corrosion, and elastomer deterioration, I didn't see anything that looked like erosion wear. Seems like this is a desig...

Re: Diesel corrosion

Were are you seeing this erosion wear? UST floor under fill line? Somewhere else?

Re: Diesel corrosion

Interesting, Zane. How are you defining pressurized piping (i.e., what pressures are you talking about?)? Product delivery to retail and fleet UST? I've only seen gravity flow deliveries, except for home heating oil delivery where product is often pumped from the truck to the tank (AST or UST). The ...

Re: Diesel corrosion

Bummer, Zane: I just wrote a reply to your last post. But if vaporized when I clicked "preview." Rather than rewrite the whole post I'll cut to my bottom line: New information can be very useful for indicating the most cost effective means of minimizing corrosion damage to fuel dispensing systems. H...

Re: Diesel corrosion

I recall reading about the planned study and applaud the effort. One tough issue to grapple with, is sample size. There are statistical tools that can be used to determine the size of a representative population - the number of tanks/dispensers from which samples must be collected and tested in orde...

Re: Diesel corrosion

Zane: We've both been around for more than a few years. In ancient days (as many EU dispensers still are) dispensers had suction pumps within their housing. Dates are fuzzy but my recollection is that the general shift from suction pumps to submerged turbine pumps occurred in the late 80s - around t...

Re: Diesel corrosion

No argument here, Zane. Except that few manifold spill containment wells are all that water-tight. Consequently, invariably, water accumulates in spill containment wells. Once there it goes through nearly daily cycles of evaporation and condensation. If hydrocarbon, ethanol, or both are part of the ...

Re: Diesel corrosion

Okay, Zane. I'm guessing that - like me - you have seen >1,000 turbine distribution manifold sumps (spill containment wells). What percentage (of those in operation for more than a few months) have been have been corrosion-free? What percentage have had moderate to heavy corrosion covering the turbi...

Re: Diesel corrosion

Funny, Zane: I have yet to see data on: 1. Historical in UST corrosion rates or incidence of corrosion related failures (with approximate cost per incident). 2. Current, annual incidence rates (same as #1). Without both of these, I'm scratching my head about your comment about the issue has been res...
