Snyder Industries 550 Gallon ASTM XLPE Captor Black Double Wall Tank

Warmer duty, outdoor light, and the plants that need both

Two things about the duty put this part number on a site rather than one of its shellmates, and the first is temperature. This sheet's own service limit is 140 F / 60 C, which is the highest figure anywhere in this shell group, and it is the reason a plant with a warm room, a jacketed line, a summer yard or a process stream that arrives above ambient specifies this listing rather than another. We cite that figure exactly as this sheet gives it and we do not borrow a number from the twin part numbers standing beside it, because the limit that matters to you is the one printed against the part number you actually order. Ask us and we will read you each sheet's own figure before you decide. The second is light. The shell is black, which keeps daylight out of the contents, and that is what a buyer is choosing when the vessel is going under a canopy, beside a roller shutter that stands open all day, next to a window in a finishing shop, or outdoors in a yard. What it costs is the level reading: on an opaque white tank an operator sees the liquid through the wall from across the bay, and on this one the only published opening is a manway on top, so decide how the level gets read before the tank is set. The sheet publishes no gauge, no sight arrangement and no level switch. Put those two together and the duty picture is specific: chemical feed and holding at a wash rack, a quarry or wash plant reagent station, an outdoor dosing point at a treatment works, agricultural and horticultural chemical storage under a canopy, a metal finishing or plating line beside daylight, and warm process feed inside a building where ambient runs high. Five hundred and fifty gallons is a working holding at those duties, big enough to take a part load and keep the bulk chemical cost per gallon sensible, small enough to turn over. This sheet also publishes something most of the range does not: 8 lifting lugs, ladder lugs and one flange line. That changes the rigging plan and is worth knowing before the crane or the forklift is booked. The pad carries 4,587 pounds of water and 8,715 pounds at the published 1.9 rating on a 76 inch square, and at 65 inches this is a low, stable vessel. Size it on consumption with the tank sizing calculator, take the freeboard discipline from the tank sizing guide, and read the Captor double wall freeboard sizing guide before you treat the nameplate figure as usable volume. Where the second wall is going into a written spill prevention plan, our Captor double wall spill prevention walkthrough is the place to take it, and nothing here claims a rule or an approval. Where the duty in question is private fire water storage rather than chemical holding, that is a different design problem entirely and the fire water reservoir design guide for rural and remote sites is where to start on it; nothing on this page is a claim about that use.

The same 76 inch shell under four listings

Four part numbers, one 76 by 76 by 65 inch shell, four names. Three of them are listed at 315 pounds and the fourth, SII-5040000N42, is listed at 670 pounds and spelled with a prefix the others do not carry. We print the weight and the spelling exactly as the sheet gives them and explain neither, because the sheet explains neither and a part number ordered against a drawing has to match character for character. The two differences you can act on are colour and service limit. This listing is black and carries 140 F / 60 C on its own sheet; the shellmates carry their own figures on theirs, and each of our pages cites only its own. Ask and we will read you all four before you commit. The other two rows are the size decision and they are not symmetrical. 5780102N42 holds 500 gallons on a 53 inch plan by standing 81 inches tall at 290 pounds, so it saves floor and spends height, and it puts the manway well out of reach from the ground. 5990902N30 holds 750 gallons on a 73 inch plan at 67 inches and 390 pounds, which is two hundred more gallons on a slightly smaller footprint and only two inches taller than this tank. If your consumption is anywhere near the top of what a 550 holds, that row deserves a serious look before you order this one.

Taking product out of a tank whose only opening is on top

• The discharge path: the outlet field reads "1 Manway / Lid" and the inlet field is blank, so no outlet dimension, thread, bulkhead, flange or valve is published on this sheet and none is claimed here. The arrangement built at this size is a suction line and strainer through the manway to a pump beside the tank. Give us the duty, the temperature, the line size and the pump and we will confirm what this part number carries before anything is ordered.
• Prime on a low shell: at 65 inches the static lift is short and a self-priming or diaphragm pump holds prime easily, which is one reason this proportion suits a permanently installed feed. Keep the suction short, rising steadily, with no high point to trap gas.
• Temperature at the pump: the wall on this sheet is rated to 140 F / 60 C, and the pump, the hose, the strainer and the seals are each rated separately. The tank rating is not the system rating, and on a warm duty the weakest of those parts is what sets your working limit.
• Level on a black shell: nothing is visible through the wall, and the sheet publishes no gauge, sight arrangement or switch. Design the level indication and the low level cut-out with the installation.
• The opening: an 18 inch threaded vented manway, the only one published, doing duty as the fill route, the inspection route and the cleaning access at once. At 65 inches it is reachable from a single step.
• The vent: listed as vented. Keep the path clear, inspect it whenever the manway is open, and never blank it to hold an odour.
• Structure: this sheet publishes 8 lifting lugs, ladder lugs and one flange line. Follow the maker's rigging instructions for them; nothing beyond the published record is claimed.
• The space between the walls: no monitoring port, gauge or alarm is published, so that arrangement is specified separately.
• Limits: 140 F / 60 C, a specific gravity rating of 1.9, and a 3 Year Warranty, as this sheet gives them.

Name the product and its strength when you order. On a contained vessel the seal and the suction fitting are the only route a release can take, and both are selected against the chemistry rather than from a catalogue default.

Yard side chemical feed with the light kept out

A black contained tank on this low, wide shell goes where an opaque white one would be working against the light and where the duty runs warm: an outdoor dosing point at a treatment works, a truck or rail wash rack, a quarry or wash plant reagent station, agricultural and horticultural chemical storage under an open canopy, a plating or finishing line beside a window, a boiler house or cooling tower feed in a warm plant room, and any yard-side point of use where a spill still has to be contained. Five hundred and fifty gallons is the practical part: it takes a part load rather than drums, it needs no bund constructed round it, and at a shade over five feet tall an operator can see into it from one step. Where it stands outside, walk round it after weather and after any traffic near it, and keep the interval for looking into the space between the walls the same in January as in July.

Class 300, one pallet, and the route through the door

Philippi, West Virginia is the plant named on this sheet, and the sheet lists Mississippi and West Virginia as ship-from states against that one plant. Freight is LTL at class 300 with no NMFC number, and the shipment is the tank at 76 by 76 by 65 inches and 315 pounds. Price the lane to your own ZIP with the freight cost estimator; the listed price is before freight. Width rather than height is what plans this move: a shade over six feet square wants a roller shutter or a bay door and a straight run with turning room at the end, while at 65 inches the height clears almost anything on the route. Measure the narrowest point, not the widest, and do it before the truck is booked. Take it under the base or on the rigging the published lugs are there for, and never by the manway. Set it on the finished, cured, level surface in its final position, check it is plumb in two directions and secure it against being knocked before anything is connected. Fill it with clean water, hold that 4,587 pound load, and read the manway seal, the whole base and the surface under it in daylight. Drain it, let it dry, open the space between the walls and record the date on the shell. Because the shell is black, do one extra thing while the water is still in it: paint your working full level and your stop level on the outside, since from that day on nobody is reading a level through this wall. 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.
