Snyder Industries 1500 Gallon ASTM XLPE Double Wall Tank

Reading the level through the wall of a large tank

Two things put this part number in a room rather than its black twin, and the first is the wall you can see through. Natural white lets an operator read the working level from the floor, and on a vessel this size that matters more than it does on a small one: the only published opening is an 18 inch manway at 76 inches, so without a pale shell every level check is a climb, and a climb that happens ten times a shift eventually stops happening at all. Put this tank where somebody has to know the level at a glance and where the light is artificial rather than direct. The second is the service limit. This sheet publishes 140 F / 60 C where the black listing on the identical 93 by 93 by 76 inch shell at the identical 950 pounds carries a lower figure on its own sheet. We print each sheet's own number on its own page and borrow nothing across the pair, because the figure that governs your installation is the one against the part number you actually order. If your duty runs warm, that line is the reason this row exists. Then the ground, which at this volume is the real constraint. Above a 93 inch square footprint sits 12,510 pounds of water at 8.34 pounds per gallon and 23,769 pounds at the published 1.9 rating, and that goes on a ground bearing slab or on a base designed for it, level and continuous across the whole footprint with nothing packed under a corner. Get it signed off by whoever owns the structure before the order, because nobody moves a tank of this size to fix what is underneath it. Containment is what you are buying along with the volume: no kerb, no coating specification, no drainage detail and no floor committed permanently to one layout, and the second wall moves when the process moves. Access and route are the last two. Seven feet nine of width means a wall opening, a large shutter or an outdoor position, and at 76 inches tall the manway needs a proper platform rather than a step, with the fill connection brought down to working level so nobody works off the shell. Leave a walkway on all four sides. Three references belong before the order. 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 explains why a liquid side inspection misses it. The usable volume and the real headspace are not the nameplate figure, which the double wall freeboard sizing guide covers properly, and your own turnover belongs in the tank sizing calculator with the freeboard discipline from the tank sizing guide. Where the reason for the tank is private fire water storage rather than chemical feed, that is a separate design problem and the fire water reservoir design guide for rural and remote sites is where to start; nothing here is a claim about that use.

The ninety-three inch shell and the two tall Captors

Four part numbers sit on this one shell and differ on paper in name, colour and material field alone; the sheet explains none of it and this page will not guess, because a product name carries no specification with it. Where a drawing, a spares list or an existing installation already names one of these, order that one and we will confirm the published figures against it before anything ships. What you can act on here is colour and temperature. This row is the natural white, cross-linked listing, and its sheet is the one in the group that publishes 140 F / 60 C; the black rows publish a lower figure on their own sheets and keep daylight off the contents instead. That is the whole of the honest comparison within the four. The two Captor rows are a different proposition entirely and worth a hard look before you settle. Both stand on a 76 inch square plan, well over a foot narrower than this tank in each direction, and both trade that back in height: 1100 gallons at 104 inches and 650 pounds, and 1550 gallons at 136 inches and 780 pounds. The taller of the two holds a little more than this tank on roughly two thirds of the plan area, at more than eleven feet of height. If floor space is the thing your site cannot spare, that row deserves the argument. If the building is low, or if you would rather not own a permanent access platform and everything that comes with maintaining one, this 93 inch shell is the easier tank to live with for the next twenty years.

Eighteen inches of access, seventy-six inches up

• The outlet: the outlet field reads 1 Manway / Lid, which names an opening and not a pipe size, and the inlet field is blank. No outlet dimension, thread, bulkhead, flange or valve is published on this sheet, so none is claimed. Give us the duty, the line size and the pump and we will confirm what this part number carries before the order is placed.
• The opening: an 18 inch threaded vented manway, the only opening on the sheet. Everything that has to go into or come out of a 1500 gallon vessel shares it, so the fill line, any suction and any instrument you want to drop in are one drawing, not three decisions taken separately.
• Reaching it: the top is at 76 inches. Design a proper platform with the installation, bring the fill connection to working level, and keep both the driver and the operator off the shell itself.
• The vent: the manway is listed as vented. At this volume the vent path is doing real work on every fill and every hard pump down; keep it clear, inspect it whenever the manway comes off, and never restrict it to control an odour.
• The space between the walls: no monitoring port, gauge or alarm is published. Write the procedure for watching and recording it, name an owner and put it on a schedule; on a vessel this size that record is the only evidence the second wall is still doing its job.
• Structure: the sheet publishes no lifting lugs, no ladder lugs, no flange lines, no stand and no level device.
• Limits: 140 F / 60 C, a specific gravity rating of 1.9, and a 3 Year Warranty, as this sheet gives them.

Tell us the product and its strength when you order. The manway seal, any fitting we add and the pump arrangement follow from the chemistry, and a generic choice there is the one that fails first.

Treatment plants that dose all day

A pale 1500 gallon contained tank belongs where the level is a number somebody quotes at a shift handover: coagulant and polymer storage at a municipal water or wastewater works, disinfection chemical holding at a treatment plant, clean-in-place and sanitising chemical stores on food, beverage and dairy lines, cooling tower and boiler house treatment at scale, pulp and paper additive feed, and plating and surface finishing lines running continuously. The white shell is doing work in all of those: a level that can be read from the floor is a level that gets read, and on a tank taking full truck drops the difference between knowing and guessing the ullage is the difference between a routine fill and an incident. The published 140 F / 60 C on this sheet is the second reason it lands in warm rooms specifically. And the economics are the third: at 1500 gallons a site is buying at a bulk chemical cost per gallon that no tote programme reaches, and the tank is paid for in truck drops rather than in years.

A seven foot nine shipment and the route to the pad

Two plants are listed on this sheet, Chowchilla, California and Lincoln, Nebraska, with California and Nebraska as the ship-from states, which is a genuinely useful pair of lanes: the plains and the Midwest are close to one of them and the West is close to the other. Freight is LTL at class 250 with no NMFC number, and the shipping size is given at 93 by 93 by 76 inches at 950 pounds. Price the lane to your own ZIP with the freight cost estimator; the listed price is before freight. Plan the offload rather than improvising it. Nine hundred and fifty pounds is straightforward for a forklift and impossible for two people, and seven feet nine of width will not thread through a building, so agree the offload point, the machine and the final position before the truck is booked. Take it under the base with the forks square, never by the manway. Set it on the finished, cured, level surface where it is going to live, confirm it is sitting flat with no rock at any corner, and only then connect anything. Fill it with clean water, hold the 12,510 pound load, and read the manway seal, the whole base and the slab under it. Drain it, let it dry, open the space between the walls, look in good light and record the date on the shell. Then use the one advantage this pale shell gives you and mark the outside at the levels that matter, full and stop, in paint while the water line is still visible; on a tank taking full truck drops, those two marks are worth more than any instrument nobody calibrates. 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.
