Snyder Industries 10000 Gallon ASTM XLPE Double Wall Tank

The slab you have already poured

Where this tank sits is often a slab that already exists, and that is the first thing to check rather than the last. At 6,400 pounds empty this is the lightest listing on the 142 by 142 by 226 inch shell, and the sheet gives 83,400 pounds for a full charge of water or 125,100 pounds at the published 1.5 rating. If you are replacing an existing vessel on an existing base, those are the three numbers to hand to whoever owns the structure, along with the 142 inch footprint, before anything is ordered. A retrofit onto sound, level, evenly bearing concrete is the cheapest installation in this catalogue; a retrofit onto a base that was poured for something lighter is the most expensive, and the difference is found by asking in advance. Where the pad is new, it is a designed slab on a designed subgrade, level across the whole base, with nothing packed under one edge to make it sit flat. The other half of the site argument is the containment area. A single wall vessel of this size normally stands inside a bund with walls, a floor, a sump and rainwater to manage; this listing carries the second wall with it, so the concrete is the pad and nothing else, and the tank can sit where the process wants it rather than where an enclosure fits. No monitoring port, gauge or alarm for the space between the walls is published on this sheet, so that arrangement is specified separately and it is worth specifying, because being able to show the space is still empty is the whole value of a second barrier. Before the order, read the wall thickness at the vapour saturated headspace guide, because the hardest service a polyethylene wall sees is above the liquid rather than under it, and the Captor double wall freeboard sizing guide, because the usable volume of a contained tank is not the nameplate figure. Then run your numbers through the tank sizing calculator and the tank sizing guide.

Three ten thousands and an eight thousand seven hundred

Read that table carefully, because the sheet contains something it does not explain: two listings carry the same name, ASTM XLPE Black, on the identical 142 by 142 by 226 inch shell at 6,400 pounds and 7,400 pounds. It is also the reason to order by part number rather than by name on this family. The case for this listing against its shellmates is its own three fields. It is cross-linked linear polyethylene, natural white, rated at a specific gravity of 1.5 with 125,100 pounds of max contents, and it publishes 140 F / 60 C where the sulfuric acid listing on the same shell publishes a lower limit on its own sheet. So this is the 10,000 to price when the duty runs warm, and the one to look past when the liquid is significantly heavier than water, since the high density listings in this family carry a higher rating on their own sheets. Natural white is the third argument, and it is practical: on a vessel with one opening nineteen feet up, a lighter wall is the level reference somebody actually uses. The 8,700 gallon row is the honest alternative if the budget or the crane is tight, at 197 inches and 5,000 pounds on the same plan.

The published outlet, and the manway above it

• The outlet: the field reads "1 Manway / Lid", with the inlet field blank. That is an opening, not a pipe size, so no outlet dimension, thread, bulkhead, flange or valve is claimed on this page. Give us the duty, the line size and the pump and we will confirm what this part number carries.
• The manway: 18 inches, threaded and vented, and the only opening on this sheet. It is the fill route, the inspection route and the cleaning route at once.
• The vent: listed as vented. The air has to move as fast as the liquid does during a bulk fill or a hard draw, so keep the path clear and never blank it to hold a smell back.
• Height to the top: 226 inches, close to nineteen feet. Fixed access, a fall protection arrangement and a fill connection at ground level all belong in the installation design.
• Structure: the sheet lists eight lifting lugs, ladder lugs and two flange lines, with no position, rating or size published for any of them.
• The space between the walls: no monitoring port, gauge or alarm is published, so that arrangement is specified separately.
• Limits: 140 F / 60 C on this sheet, a specific gravity rating of 1.5, and a 3 Year Warranty.

Tell us what goes in it when you order. On a contained vessel every wetted part is chosen against the chemistry, and the fitting is the one route a release can take out of a tank that otherwise has two walls.

Warm feed and wash-down chemistry at plant scale

The service limit on this sheet is what puts the tank on the list, and the duties follow it: clean-in-place and sanitation chemical storage at food, beverage and dairy plants, heated wash and rinse supply, boiler and cooling water conditioning, metal finishing and plating at plant scale, pulp and paper process chemistry, and bulk storage standing outdoors where a summer roof works on the headspace all day. It is also a straightforward replacement for a steel tank inside a bund that has failed its own inspection, because the containment comes with the vessel rather than with the concrete. Two pieces of reading pay for themselves before the order goes in. The hardest service a polyethylene wall sees is at the vapour line rather than under the liquid, which the wall thickness at the vapour saturated headspace guide works through, and it matters more on a warm duty. And the usable volume of a contained tank is not the nameplate figure, which is the subject of the Captor double wall freeboard sizing guide. Put the tank where somebody walks past it on a normal shift, not behind the stillage racking.

The lightest of the ten thousands

Nebraska is the only ship-from state on this sheet and Lincoln the only plant, which puts the plains and the Midwest on the short lane. The ship mode is given as LTL at class 250 with no NMFC number, and the shipping dimensions as 142 by 142 by 226 inches at 6,400 pounds. Price your lane with the freight cost estimator; the listed price is before freight. At 6,400 pounds this is the lightest vessel on its shell, which changes the lift arithmetic and nothing else: it is still nearly twelve feet across and an oversize move. The sheet publishes no crane capacity, no rigging arrangement, no permit and no escort detail, so none is stated here and all of it is agreed with your carrier and your rigger against the published dimensions and weight. Check the gate, the turning circle, the overhead lines and the standing position for the lift before the truck is booked. Lift by the arrangement the rigger specifies, never by the manway. Set the vessel plumb on the cured pad, confirm the full 142 inch base is bearing evenly, then fill with clean water and hold the 83,400 pound load while you read the manway seal, the base line and the pad edge. Drain it, let it dry, open the space between the walls and write the date and the part number on the shell in paint marker. Walk the pad edge again after the first hard rain; ground that is going to move shows it at the edge first. A photo of the tank on its pad, full, on day one is worth keeping; it is the baseline every later inspection is compared against.
