Snyder Industries 12500 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank

Sixteen feet six inches, out of Lincoln at class 300

The plant is Lincoln, Nebraska, the class is 300, and the shipment is what makes this tank the friendliest delivery of the bulk cross-linked range: 142 inches across and 198 inches long, sixteen feet six inches rather than nineteen or twenty-one. It is still an over-dimensional deck load that needs a permit and a route, but a shorter shell is easier to secure, easier to clear under obstructions on the way in, and easier to stand up in a yard with a modest crane, so the same central lane costs less trouble here than it does on the tall shells. Price it to your ZIP in the freight cost estimator and read the listed price as before freight. The pad is where the 1.9 rating shows up. It allows 198,075 pounds of contents where plain water in this shell would be 104,250, and because a rotationally molded floor bears on its whole floor, all of it lands on the 142 inch circle. Engineer the slab to the concrete pad sizing framework, level and in full contact, inside containment sized to the tank, and on a hot dense liquid treat the containment as the local requirement it usually is. A shorter tank is the least wind-sensitive shape at this volume, which is exactly why people skip the bands on it; do not. An empty 4,200 pound shell still moves in a gust, so it gets banded to structure or to slab anchors the day it lands. Check 12,500 gallons against your draw in the tank sizing calculator, and take the reserve and the thermal freeboard a warm liquid needs from the tank sizing guide.

The cross-linked 12,500 among three 3,100 pound shells

Three other walls are molded in this same 142 by 198 inch shell and the sheet lists all three at 3,100 pounds empty against this tank's 4,200, so the extra wall is visible on the scale before it is visible anywhere else. The reason to pay for it is the pairing: this is the only row at 12,500 gallons carrying both the 1.9 rating, worth 198,075 pounds of allowed contents, and the 140 F / 60 C service limit. The 5350000C34 is the heavy-duty wall at the lower temperature limit, which is the right buy for a dense liquid that stays cool; the 5350000C37-BLACK is the lighter rating for something near the density of water; the 5350000N40 is the other wall listed in this footprint, rated as its own sheet says. The SII-32074 sits just below at 12,000 gallons and 197 inches and is listed at 2,482 pounds empty, the lightest shell in the group. If the volume has to grow and the yard can take the width, the 3030100C26 puts 15,000 gallons on a 165 inch base at 184 inches.

The 18 inch lid at 198 inches, and the field that reads 30

• Access is the least awkward part of this tank and it is still overhead work: an 18 inch threaded, vented manway at 198 inches, sixteen feet six inches above the pad. That is a fixed platform with a rail and a gate or a caged ladder to a landing, and it is a shorter climb than the tall shells at this volume ask for, which on a warm liquid that gets inspected often is worth real money over a decade. An 18 inch opening passes a cleaning wand, a level probe and a vent line at once and passes no person.
• Outlet: the sheet gives the outlet field as "30" and gives no pipe size anywhere on it. A bare number is not a diameter, so we print the field as it stands: the sheet lists the outlet as 30. Name the liquid, the temperature you hold it at and the draw-off you want at order, and we confirm what this molding accepts and in what material before anything is cut.
• Structure: the sheet notes ladder lugs and one flange line. They carry what they are named for and nothing else gets hung on the shell.
• Fill and vent: a dip tube to the floor, because even sixteen feet of free fall will foam a warm liquid and splash the gasket seat; the vent piped outdoors on anything that fumes and sized to the delivery pump rather than to the nearest port.
• Service limit: 140 F / 60 C. Warranty: 3 year. Rating: specific gravity 1.9 as the sheet gives it.

A hot dense liquid in a shorter shell is a gentler duty on the base fitting than the same liquid twenty-one feet up, but the rules do not change: base piping on its own support off the pad, a flexible connector between shell and hard pipe, and nothing rigid bolted to the tank, because polyethylene moves with temperature and a run aligned cold is not aligned hot. The headspace band above the liquid line ages before the wetted wall, so a light goes on it at every opening with the date on the log. A black wall shows no level, which makes the sender the gauge and a stick through the manway the annual check on the sender. Put the liquid's name and the service limit on the wall where the next operator reads them, and in a climate that freezes as well as bakes, protect the base valve and the first pipe run rather than the body.

Hot chemistry that only needs 12,500 gallons

This is the tank for a warm dense liquid where the volume is a tanker rather than an inventory: a plating or metal finishing plant holding a bath chemical at working temperature, a heated caustic or cleaning solution at a food or industrial plant, a dense process liquid coming off a heat exchanger, a drilling or mining yard with a heavy brine on a pad that runs hot all season, and a distributor holding a warm product in a building whose roof will not take nineteen feet of tank. Before committing, settle whether the chemistry actually needs a cross-linked wall or whether a high-density wall carries the same duty for less: our guide to when cross-linking matters for chemistry duty goes through it chemical by chemical, and that choice is much harder to revisit than the piping is. Water at 8.34 pounds per gallon sits far inside the 1.9 rating, but a private fire reserve is a separate specification in a water-rated vessel, and the fire-water reservoir design guide sets out why a chemistry-duty wall is the wrong purchase for that job.

4,200 pounds on a 142 inch footprint

The sheet gives class 300 and 4,200 pounds shipping weight from Lincoln, Nebraska, shipping at 142 inches by 142 inches by 198 inches. Of the cross-linked tanks in this range it is the shortest shipment and the second lightest pick, which makes it the one most likely to fit a yard's existing crane and a carrier's ordinary permitted routing rather than a special one. Straps go under the body, never a sling through the manway, and the tank sets down on the cured pad inside its containment on the first move rather than being staged and dragged. Then fill it with cold water to the manway and hold it there while the base and the containment floor are walked twice, looking for movement at the pad perimeter or a weep at any fitting, and drain and dry it before the working liquid comes up to temperature. Walk the pad edge again after the first hard rain, because ground that moves shows it at the edge before it shows anywhere else. Tape a copy of the spec sheet inside the control panel door; the next person to touch the tank will not have the box it came in.
