Snyder Industries 8700 Gallon ASTM XLPE Black Double Wall Tank

Plant room floor or outdoor pad

Two positions suit this tank and they ask for different preparation. Indoors, on a plant room or process hall floor, the argument for containment moulded into the vessel is that nobody has to build a kerb, take up floor area with a bund or work out where a bunded floor drains to. What the building has to give instead is clear height: 197 inches of shell plus whatever a platform and a fill arrangement need above the manway, measured at the final position rather than scaled off a drawing. Outdoors, on a pad beside the process building, the argument is the same but the ground work is larger, and the pad has to be designed for 72,558 pounds of plain water or 108,837 pounds at this sheet's 1.5 rating standing on a 142 inch square. Flat, continuous, level across the whole footprint, cured before delivery, with no rails and nothing packed under a corner. Either way, leave a walkway all the way round before the pipework is laid out. The black shell is worth planning for wherever it stands. With the only published opening at 197 inches, nobody is reading a level through this wall, so decide how the level is read while the tank is still on paper; on an outdoor pad that decision is also the one that keeps somebody off a ladder in bad weather. What makes this the row to order is the pair of figures on its own sheet: a 1.5 rating for a product not much denser than water, and a 140 F / 60 C service limit, which is the higher of the two limits in this shell. Warm and not especially dense is exactly the combination this listing is written for. Size it honestly before you order, because a warm product does not give you the nameplate volume: run the numbers in the tank sizing calculator and take the freeboard discipline from the tank sizing guide.

The lighter pair among the four 8700s

This tank and 1006400N49 are the pair listed at 5,000 pounds; the other two rows on the same shell are listed at 5,800. Within that lighter pair, this is the one whose sheet reads 140 F / 60 C and whose material field reads crosslinked linear polyethylene. That is the whole published difference, and it is the honest reason to order this part number: warm service on a product carrying the 1.5 rating, which here allows 108,837 pounds of maximum contents against 72,558 pounds of plain water. If nothing on your site approaches the limit, the limit should not be choosing your tank and the chemistry should. If the product is genuinely dense, neither of the lighter rows is right and the heavier listings are the ones to price. No sheet in the group explains what the codes mean, so this page offers no interpretation of them; describe the product, the strength and the working temperature and we will name the part number and confirm the published figures against it. The two outside rows are the only size steps this sheet publishes. 5670000N30 is 6,500 gallons on a smaller 120 inch square at 199 inches, and 1006600N30 is 10,000 gallons on this same 142 inch plan at 226 inches. The second of those is the comparison most sites should do properly, because the pad and the ground work are identical and the extra volume is bought only in height, which usually shows up as fewer truck drops rather than as anything you notice on the installation.

What the outlet line publishes on this sheet

• The outlet: the field reads "1 Manway / Lid" and the inlet field is blank. That is an opening being named, not a pipe size being specified, so this page claims no outlet dimension, thread, bulkhead, flange or valve. Tell us the duty, the temperature and the line size and we will confirm what this part number carries before a pump is chosen.
• The opening: an 18 inch threaded vented manway, the only opening on the sheet. Fill, inspection and cleaning share it, and 18 inches is wide enough to work a lance and to look properly at the wall, which is the point on a vessel this size.
• The vent: listed as part of the manway. On a sheet rated to 140 F / 60 C the headspace moves more air for the same change in level, so the vent path is the first thing to inspect and the last thing to restrict. Never blank it to hold back an odour.
• Warm duty: if the product runs near the published limit, say so at order time, because gasket material, valve seats and flexible connections are chosen against temperature as well as against chemistry.
• Access: the manway is at 197 inches. A fixed ladder or platform, a fall protection arrangement and a ground level fill connection are designed with the tank, not improvised on the day.
• Structure: the sheet lists 8 lifting lugs, ladder lugs and one flange line, and nothing else.
• The space between the walls: no monitoring port, gauge or alarm is published on this sheet, so that arrangement is specified separately and inspected on a written schedule.
• Limits: 140 F / 60 C, a specific gravity rating of 1.5, and a 3 Year Warranty.

Give us the product, the strength and the working temperature together, and the whole wetted system is specified once instead of corrected after the first warm batch.

Warm water and dilute chemistry

A 1.5 rating with the higher service limit is a combination that suits warm, water-like duty at bulk volume: clean-in-place and sanitation make-up in food, beverage and dairy plants, heated rinse and wash-down supply, boiler house and cooling tower treatment storage, dilute solution holding at a water or wastewater works, laundry and industrial wash operations, and process water buffering in manufacturing where the room itself runs warm. At 8,700 gallons the site is receiving by hose on a schedule rather than moving totes, and the second wall is what allows that to happen indoors or on a surface that drains somewhere. Two references belong before the order rather than after an inspection. The usable volume of a contained tank is not its nameplate figure once thermal expansion, chemistry and density are accounted for, which the Captor double wall freeboard sizing guide works through, and warm service is exactly the case where the gap between nameplate and usable is widest. Where private fire water storage is the reason for the enquiry, that duty is sized on different rules and the fire water reservoir design guide for rural and remote sites is where to start; nothing here is a claim about it. Whatever the duty, put the inspection of the space between the walls on a fixed schedule from the first week and write down what you saw.

The shipping size is 197 inches tall before it is loaded

Lincoln, Nebraska is the plant and Nebraska the one ship-from state on this sheet. The ship mode is LTL at class 250 with no NMFC number, and the load is 142 by 142 by 197 inches at 5,000 pounds. Price the lane to your own ZIP with the freight cost estimator; the listed price is before freight. The sheet publishes no crane, rigging, permit or escort detail, so none is stated on this page, and the planning has to be done from the dimensions instead. Over sixteen feet of tank sitting on a trailer bed is taller again than it is on the ground, which is what catches people out on low bridges, gate frames and roller shutters; walk the route before the truck is booked and confirm the offloading equipment has reach as well as rating. Take it under the base by the arrangement your rigger specifies and never by the manway. Set it plumb on the cured, level surface in its final position, confirm the whole 142 inch footprint bears evenly, and only then connect anything. Fill with clean water, hold the 72,558 pound load, and read the manway seal, the base line and the pad while it is under load. Drain it, let it dry, open the space between the walls and record the date and the part number on the shell. Then do one thing that pays for itself on a warm duty: note the ambient and the product temperature at that first fill alongside the inspection date, so the next person has a baseline for what normal looks like on this tank. Put the tank's part number on the maintenance log the day it lands; five years on, nobody remembers which shell it is.
