Snyder Industries 5500 Gallon ASTM XLPE Black Heavy Duty Vertical Storage Tank

Freight from Lincoln or Philippi on a tank that clears a lower roof

Molded in two places, priced from one. Lincoln, Nebraska covers the Plains, the upper Midwest and the Mountain West; Philippi, West Virginia covers the Atlantic states, the Southeast and the Ohio Valley; the order goes to whichever plant gives the shorter lane to your ZIP, and the freight cost estimator prices it before you commit. At 120 inches across and 132 inches long on the deck it is a permitted load, not an escorted one, so the lane is about miles. The roof is the other reason to buy this shell: eleven feet leaves room for a platform, a vent line and a fill line under a bay where the taller tanks on the same base leave nothing. Full at the rating it puts 87,153 pounds, more than forty tons, on a ten foot circle, and a rotationally molded floor bears on the whole slab, so the pad is engineered per the concrete pad sizing guide, level and in full contact, inside a berm sized to 110 percent where the liquid is regulated. Eleven feet of empty black tank still catches wind; strap it to structure before the first fill and look at the straps after the first windy week and the first summer. The black wall keeps light off the load, runs warmer than white in the sun, and hides the level, so a sender read at the ground is the gauge. The tank sizing calculator checks 5,500 gallons against the dosing rate and the truck schedule; the tank sizing guide covers the reserve and the headspace a dense liquid needs as it warms.

The 7000000 shell: four grades, three weights

Four cross-linked tanks share this shell and the sheet separates them by weight: this N48 at 1,450 pounds with the 1.9 rating, the N46 and the N40 at 1,155 pounds, each rated as its own sheet says, and the N42, which the sheet lists as heavy duty at 750 pounds; the sheet gives all four and we print them as given. This is the tank when the liquid is dense and aggressive at once and the roof is under twelve feet. If the roof is lower still, the 7000400C26 lays 5,400 gallons down to 91 inches on a 142 inch base at 750 pounds, and the 5250000N40 puts 5,600 gallons of cross-linked wall at 102 inches on the same wide base; both trade floor for height.

Eleven feet to the lid

• Access: 18 inch threaded, vented manway at 132 inches, eleven feet off the pad. A rolling stair with a top rail reaches it; a fixed platform is better where the lid opens more than a few times a year. Fill through a dip tube to the floor, vent outdoors on a liquid that fumes, and size the vent to the delivery pump.
• Outlet: the sheet's outlet field reads 24, a bare number with no size, thread or material on it; we print it as given. Name the liquid at order and the bulkhead fitting, gasket and bolting are specified to it, with a flexible connector to hard pipe and the first valve on its own support.
• Service limit: 140 F / 60 C.

Eleven feet is close enough to the ground that the manway gets opened more than it should, so the rule on this tank is the same as on the tall ones: the lid opens for inspection, and the level, the sample and the fill all happen at the ground. Eleven feet of head keeps a transfer pump set below the outlet flooded to the last few inches, and a low-level float stops it before it draws air. The lid stays shut between deliveries so vapor stays in and rain stays out, the wall names the one chemical inside, and the headspace band gets a light at every opening. Where it freezes, trace or wrap the valve and the first pipe run; the body ices from the top down without harm.

Dense chemistry in a shorter bay

Sulfuric or hydrochloric acid at strength in a chemical building with a low roof, ferric at a water plant that stores in the sun, and the hot, dense process liquids at a plant that would push a linear wall on temperature and density together. Whether the liquid needs cross-linking at all is the question the cross-linked versus linear polyethylene guide answers. When site rules call for a second wall, the Captor double wall freeboard guide works out what a contained tank gives up in usable volume at this size. A fire reserve wants a water wall; the fire-water reservoir design guide explains why, though water is far inside this tank's rating.

Class 300, and what to do the day it lands

The 7000000N48 ships from Lincoln, Nebraska or Philippi, West Virginia as freight at class 300 as the sheet lists it; at 120 inches across and 132 inches long on the deck it is a permitted load, the listed price is before freight, and the freight cost estimator prices the lane from the plant that will mold it. A crane or a forklift with long forks stands 1,450 pounds up with straps under the body, never through the manway, and the straps to structure go on the same day. Fill it with water to the manway once and hold it, watching the pad edge and the outlet fitting for movement or a weep, then drain and dry before the chemical arrives; after that the log takes the date and strength of every load. Keep one spare gasket for the outlet fitting on the shelf. Put the tank's part number on the maintenance log the day it lands; five years on, nobody remembers which shell it is.
