Re: [papercreters] tank boy

After working in the oil and gas industries for 40 years I would not put water in this tank without the most through cleaning and sealing. And then I would have it tested over and over again, hydrocarbons work their way into the tank material and then just when you do not expect it leach out. Often with fatal results. Please be careful with this. --- On Wed, 8/13/08, x <personx@mindspring.com> wrote: From: x <personx@mindspring.com> Subject: [papercreters] tank boy To: papercreters@yahoogroups.com Date: Wednesday, August 13, 2008, 5:15 PM Hello all I'm still in the planning stages and thought I would run them by you-all for your expert feedback. This is a fuel tank (1000gal. 4'dia. By 12' long) that I will be converting to a hot water tank for a solar system that will sit outside. I want to use the PC to insulate it, about 2' all around. I first thought of doing a traditional mounting with three supports on a concrete footers that went below the freeze level (2' here) and then doing the PC all around. With the concern with heat loss through the supports and how to minimize that I have now revised it to just using PC for the whole support and doing a stronger mix for the part that will support the weight of the tank (apx. 4 tons) running the full length of the tank of course. Setting it 4' below ground level on a bed of gravel using treated plywood and plastic sheeting as a vapor/water barrier. Having a couple of drainage trenches and piping running downhill from it to keep water from pooling there. Any thoughts on my ideals would be greatly appreciated. Thanks -x-
