Snyder Industries 5500 Gallon ASTM XLPE Black Double Wall Tank

Ten feet across, and what that does to the route

The lane is fixed before you choose anything: one plant, Lincoln, Nebraska, and one ship-from state, Nebraska, for every tank in this family. What varies is what has to happen at your end, and on this one the governing number is the plan rather than the height. A 120 inch square is ten feet across, which is wider than almost every door, gate and shutter on an ordinary industrial site, and the tank cannot be turned on its side to get through one. So survey the approach to the final position before the order rather than after it: the width of the gate, the swing room inside it, the surface the truck and the lifting equipment have to stand on, and the overhead services between the two. At 172 inches this is the shorter of the two shells we list on that plan, which helps under a canopy or a low run of pipework, and at 3,800 pounds empty the weight is the least of the problems. The sheet publishes no crane capacity, no rigging arrangement, no permit and no escort requirement, and no lifting lug count either, so this page states none of those and the lift is planned with your rigger from the weight and the envelope. Once the load is sorted, the reason to order this listing rather than its shellmate is the service limit. This sheet reads 140 F / 60 C where the high density listing on the same shell reads lower, and both carry the same 1.9 rating with 87,153 pounds of maximum contents against 45,870 pounds of plain water. Dense and warm, on a plan that fits under a low roof, is the combination. Work the volume out before you order, since a warm product wants more freeboard: use the tank sizing calculator and take the rules from the tank sizing guide.

The 172 inch shell under four part numbers

Four part numbers sit on this 172 inch shell and the sheet gives two of them at 3,800 pounds and two at 3,200. This tank is one of the heavier listings, and what belongs to it alone is the material field reading crosslinked linear polyethylene and the service limit reading 140 F / 60 C. Its 1.9 rating carries 87,153 pounds of maximum contents against 45,870 pounds of water. The names across the four differ and the sheet explains none of it, so this page prints the rows as given; where a drawing already names one of these part numbers, order that one and we will confirm the published figures against it, and where you are choosing from scratch, tell us the product, the strength and the working temperature. The last two rows are the only size steps published, and they are genuinely different propositions. 5630000N40 holds 5,000 gallons on a narrower 102 inch plan at 216 inches, which is a great deal more height for a smaller square and suits a tall building with no floor to spare. 5670000N30 holds 6,500 gallons on this identical 120 inch plan at 199 inches, so it is the same pad and the same ground work with the extra capacity bought in height alone. Between those two the question is simply which dimension your building is short of, and it is worth answering before you look at gallons, because on this family the gallons follow the geometry rather than the other way round.

Air and product through one 18 inch manway

• The fill opening: an 18 inch threaded vented manway and nothing else is published. Product goes in there, the inspection happens there and the cleaning happens there, so every arrangement anyone wants on top competes for one hole and all of it should be drawn before the tank is set.
• The vent: listed as part of the manway. A tank rated to 140 F / 60 C runs a warmer headspace, and a warm headspace moves more air for the same change in level, so the vent path is the first fitting to inspect and the last to restrict. Never blank it to hold back an odour.
• Warm service: gasket material, valve seats and any flexible connection are chosen against temperature as well as chemistry. Name the working temperature at order time and the wetted system gets specified once.
• The outlet field: it reads "1 Manway / Lid", with the inlet field empty. That is an opening being named rather than a pipe size being given, so no outlet dimension, thread, bulkhead, flange or valve is claimed on this page. Give us the line size and the pump arrangement and we will confirm what this part number carries.
• Access: the manway is at 172 inches, which is a fixed ladder or platform and a fall protection arrangement designed with the installation, plus a fill connection at ground level wherever the delivery permits.
• Structure: the sheet lists ladder lugs and one flange line, and publishes no lifting lug count on this part number, so none is stated here.
• The space between the walls: no monitoring port, gauge or alarm is published, so that arrangement is specified separately and inspected on a written schedule.
• Limits: 140 F / 60 C, a specific gravity rating of 1.9, and a 3 Year Warranty.

Say what is going in it and how warm it runs when you order, and nothing about the wetted system has to be revisited after the first hot batch.

Warm service at fifty-five hundred gallons

The higher limit on this sheet, paired with the 1.9 rating, puts this part number where a dense product is stored warm and the building is not tall: clean-in-place and sanitising chemical make-up at food, beverage and dairy plants, plating and surface finishing halls, warm process chemistry in manufacturing, boiler house and cooling water treatment storage, mineral processing reagent storage under a canopy, and bulk holding at a treatment works whose chemical building has a low roof. At 5,500 gallons the site takes deliveries by hose on a schedule, and the containment moulded into the shell is what allows that indoors or on a surface that drains somewhere. Four references belong before the order. The usable volume of a contained tank is not its nameplate figure, per the Captor double wall freeboard sizing guide, and warm duty widens that gap. The wall works hardest at the vapour line rather than under the liquid, which the wall thickness at the vapour saturated headspace guide explains. How the space between two walls is tested is set out in the cathodic disbondment testing guide for double wall interstitial spaces. And where private fire water is the duty rather than chemical storage, begin with the fire water reservoir design guide for rural and remote sites; nothing here is a claim about that use.

What the sheet publishes about the move, and what it does not

What it publishes: Lincoln, Nebraska as the plant, Nebraska as the ship-from state, LTL as the ship mode, class 250 as the freight class, no NMFC number, and a load of 120 by 120 by 172 inches at 3,800 pounds. What it does not publish: any crane capacity, any rigging method, any permit, any escort arrangement and any lifting lug count. Neither is guessed at here. Price your own lane with the freight cost estimator; the listed price is before freight. Plan the lift with your rigger from the weight and the envelope, take the tank under the base rather than by the manway, and keep it upright through the site. Set it plumb on the cured, level surface in its final position, check it in two directions while it is empty, and confirm the whole 120 inch footprint is bearing evenly before a pipe is connected. Fill it with clean water, hold the 45,870 pound load, and read the manway seal, the base line and the pad in good light while it is under load. Drain it, dry it, open the space between the walls, look into it and write the date and the part number on the shell. Tape a copy of the spec sheet inside the control panel door on the way out; the next person to work on this tank will not have the paperwork it arrived with. Keep the first delivery's paperwork with the tank; strength and date on day one is the baseline for every batch after.
