Snyder Industries 1100 Gallon ASTM XLPE Black Captor Double Wall Tank

Where the service limit decides the duty

This part number and the listing beside it are the same 76 by 76 by 104 inch shell at the same 650 pounds, and the field that separates them is the service limit. This sheet publishes 140 F / 60 C, the higher of the two, and that single figure is why a plant chooses it. The duty behind it is specific: a chemical store where the room runs warm, a product that arrives above ambient from a process or a heated line, a clean-in-place or wash system whose return is warm, a feed tank beside a boiler house or a steam main, or a yard in a hot climate where the summer ambient is the design case rather than an exception. The listing on the identical shell carries a lower published figure on its own sheet, and we print each sheet's own number on its own page rather than borrowing across the pair. Ask and we will read you both before you order, because the limit that matters is the one printed against the part number you actually buy. Two consequences follow and both belong in the design. A tank rating is not a system rating: the pump, the hose, the strainer, the seals and any gasket carry their own numbers, and on a warm service the lowest of them sets the working limit of the installation. And the wall's hardest service is at the vapour line rather than under the liquid, which is exactly where warm duty concentrates; the wall thickness at the vapour saturated headspace guide explains why an inspection from the liquid side misses it, and it belongs in the maintenance schedule from the first week. Eleven hundred gallons is the capacity step that suits a mid sized feed room: enough for a monthly or six-weekly drop, small enough that the liquid turns over, and, at 104 inches on a 76 inch square base, low enough to stand under most industrial ceilings with working room over the manway. The ground carries 9,174 pounds of water and 17,431 pounds at the published 1.9 rating on roughly forty square feet, so flat, continuous, level and carrying the whole footprint is the specification, with a signed calculation for anything that is not a ground bearing slab. The shell is black, which keeps daylight out of the contents and removes the level you could otherwise read through a white wall; the sheet publishes no gauge, sight arrangement or level switch, so that instrument is specified with the installation. Size it properly before ordering: the Captor double wall freeboard sizing guide covers why the nameplate figure is not the usable volume, and thermal expansion takes a larger share of that on a warm duty. Put your own draw and drop size through the tank sizing calculator and take the freeboard rule from the tank sizing guide. Where the second wall is going into a written spill prevention plan, our Captor double wall spill prevention walkthrough is the starting point, and nothing here claims a rule, a listing or an approval. Where the duty is private fire water storage instead of chemical holding, the fire water reservoir design guide for rural and remote sites is where to take it; this page makes no claim about that use.

The 1100 shell, the 1000 and the 1500

Four part numbers on one 76 by 76 by 104 inch shell at the same 650 pounds, two of them spelled with the SII- prefix and two without. Every placeholder here is spelled exactly as the sheet spells it, because a part number quoted against a drawing has to match character for character and a tidied list is a list that eventually ships the wrong tank. Two of the four are black and two are white, which is a daylight decision rather than a chemistry one, and the rest of the naming we print as given and interpret not at all. Tell us the product, the strength and the temperature and we will name the number. The two neighbouring sizes are worth pricing rather than skipping. 5990102N30 holds 1,000 gallons on an 81 inch plan at just 69 inches tall and 500 pounds, so a hundred gallons less buys you a tank you can see into from a short step and nearly three feet of headroom back. 5990302N30 holds 1,500 gallons on a 93 inch plan at 76 inches and 950 pounds, four hundred gallons more and still barely over six feet tall. Both trade floor for height, and both are easier to work on than this one. What this tank offers against them is the smallest footprint of the three at a useful capacity, plus the higher published service limit on its own sheet. If the room is tight and the duty is warm, that combination is the whole argument.

Suction, prime and the single flange line

• The suction path: this sheet publishes no outlet connection. The outlet field reads "1 Manway / Lid", an opening and not a pipe size, and the inlet field is blank, so no thread, bulkhead, flange or valve is claimed here. The arrangement built at this size is a drop pipe and strainer through the manway to a pump beside the tank, which is a suction lift from the bottom of a 104 inch vessel.
• Prime on a warm fluid: warm liquid is harder to hold on the suction side than cold, so keep the line short and rising steadily, avoid any high point that traps vapour, and give the pump a foot valve or a self-priming head. Design against a nearly empty tank on the hottest day, not a full one in spring.
• Rating the whole system: the wall on this sheet is rated to 140 F / 60 C, and the pump, hose, strainer, seals and gaskets each carry their own. On a warm duty the lowest number in that list is the installation's limit. Give us the product and the working temperature and we will specify against both.
• Low level protection: the sheet publishes no level device, gauge or sight arrangement, and the shell is black, so a cut-out is the only warning the pump gets. Fit it at installation.
• The opening: an 18 inch threaded vented manway, the only one published, serving as fill point, drop pipe route, inspection hatch and cleaning access.
• Reaching it: at 104 inches the manway is above head height, so a short fixed platform belongs in the drawing and the fill connection should come down to working level.
• The vent: listed as vented, and on a warm duty that path works harder than on a cold one. Keep it clear, inspect it whenever the manway is open, and never restrict it.
• Structure: this sheet publishes 8 lifting lugs, ladder lugs and one flange line. Rig on the lugs to the maker's instructions; nothing beyond the published record is claimed and the sheet does not say what a flange line count implies.
• 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, the strength and the working temperature at order time. On a contained vessel the seal and the suction fitting are the only route a release can take, and warm service is where a generic choice shows up first.

Warm rooms, jacketed lines and summer yards

A 1,100 gallon holding with the higher published service limit goes where temperature is part of the specification: clean-in-place and sanitation chemical in food, beverage, dairy and brewing, wash and process chemical in laundries and textile plants, plating, pickling and anodising feed, additive storage in pulp and paper, a chemical store adjacent to a boiler house or a steam main, cooling water treatment in a warm plant room, and yard installations in hot climates where summer ambient rather than the process sets the design case. The capacity suits a site taking a monthly or six-weekly drop and running a pump most of the day. Two things belong in the operating routine on a warm duty. Read the wall at and just above the liquid line every time the manway is open, because that is where the service is hardest. And keep the interval for looking into the space between the walls the same in August as in February, since the season that stresses the installation is the one people skip.

A tall narrow shipment and a single pallet position

Philippi, West Virginia is the plant on this sheet and West Virginia the only ship-from state, so the mid-Atlantic, the Ohio valley and the Northeast are the short lanes and the far West is a planned move. Freight is LTL at class 300 with no NMFC number listed, and the shipment is the tank at 76 by 76 by 104 inches and 650 pounds. Price your own lane with the freight cost estimator before you fix the capacity; the listed price is before freight. This is one pallet position at a weight most yard equipment handles, on a six foot four base and eight feet eight tall, which is a proportion that behaves well on a truck and through a bay door but still wants checking against the lowest overhead run on the route in. Measure the lowest point and the narrowest point before the truck is booked. Take it under the base or on the published lugs, never by the manway, and keep it upright wherever the building allows. Set it on the finished, cured, level pad in its final position, confirm it is plumb from two directions and secure it against being knocked before anything is connected. Fill it with clean water, hold the 9,174 pound load overnight, and read the manway seal, the base all the way round and the pad under it in good light. Drain it, let it dry, open the space between the walls and write the date and what you saw on the shell. Add the working temperature to that first record; three years on, whoever inspects this tank will want to know what duty it has actually been doing rather than what was planned for it. Note the pad height and the outlet height on the site plan while the tape is out; the next pipe run will need both.
