Snyder Industries 150 Gallon Sulfuric Acid Double Wall Tank

Marked Tree, Arkansas, and a short mid-South lane

Where the tank is made decides a larger share of what it costs to land than most buyers expect at this size, so start with the lane. Marked Tree, Arkansas is the only plant on this sheet and Arkansas the only ship-from state, which makes the mid-South, the lower Mississippi valley and the eastern plains the short runs and everything else a planned move. Freight is LTL at class 250 on a shipment of 34 by 34 by 62 inches at 110 pounds: a single pallet position, a tail lift delivery on most lanes, and a pallet truck rather than a crane at your end. That combination is the practical argument for this size. Price your own ZIP with the freight cost estimator before you compare it against a larger vessel, because the distance from Arkansas will move the comparison more than the tanks do; the listed price is before freight. The shape is what keeps the lane easy. A 34 inch square base is under three feet each way, which passes a standard doorway with room either side, and at 62 inches the tank is barely over five feet, so it goes through a building upright and can be set in a corner by two people. Check the route as well as the destination, because five feet on the floor is taller again on a pallet and the lintel is what usually stops it. What sits underneath matters more than the handling. A flat, continuous, level surface carrying the whole 34 inch footprint, no rails, no timber pallet left in place, no shim at one corner; above that base sits 1,251 pounds of water and 2,377 pounds at the published 1.9 rating on under eight square feet of floor. The framework for that surface, and the point at which a general recommendation stops and an engineer's drawing begins, is set out in the concrete pad sizing guide for above-ground polyethylene tanks. Two more things belong before the order. The usable volume and the real headspace on a contained tank are not the nameplate figure, which the double wall freeboard sizing guide works through on thermal expansion, chemistry and density; then run your own delivery quantity and turnover through the tank sizing calculator and take the freeboard discipline from the tank sizing guide. Where the reason for buying containment at all is a regulatory one, the double wall compliance walkthrough goes through the requirements in order instead of asserting that any product satisfies them.

Four 150s on one shell, plus a 120 and a 250

Four listings share this exact 34 by 34 by 62 inch shell at the identical 110 pounds, and what separates them on the sheet is the name and the colour the maker assigns. This one is named for sulfuric acid; the others are named as cross-linked, as high density, and as cross-linked in black. No sheet explains what any of those names implies and this page will not invent an explanation, because a name is not a specification and treating one as though it were is how the wrong vessel ends up in a plant room. Tell us the product and the strength you are storing and we will tell you which part number to order; where a drawing or an existing installation already names one of the four, order that one and we will confirm the published figures against it. The material field on this sheet is its own, and the sheet next to it in the same shell carries a different one; we print each page from its own sheet and never borrow across the pair. The other two rows show how cleanly this family scales, because all three capacities sit on exactly the same 34 inch plan and buy volume purely with height: 51 inches for 120 gallons at 100 pounds, 62 inches for this 150, and 83 inches for 250 at 150 pounds. That is unusually convenient. You can change your mind about volume without re-planning the floor, the bay or the route, and the constraint that decides your choice is almost always the ceiling or the fill point rather than the footprint. This 150 sits in the middle of that at just over five feet: the tallest of the three whose lid most people can still reach from the floor, which is exactly why it is the one that sells.

Comparing across brands too? Call 866-418-1777; we carry Norwesco, Snyder, Chem-Tainer, Enduraplas and Bushman and will say which one fits, or price the freight first.

Filling through the 14 inch threaded vented lid

• The fill opening: a 14 inch threaded vented lid is the only opening this sheet publishes, and at 62 inches off the floor it is reachable without a platform for most people. That is the single most practical thing about this size. Fourteen inches takes a delivery coupling, a fill hose, a drop pipe and a rinse lance, and all of them share the one opening.
• The vent: the lid is listed as vented, and that path is what keeps the wall out of trouble while a delivery fills the tank and while a pump draws it down. Keep it clear, inspect it whenever the lid comes off, and never restrict it to hold an odour.
• The outlet: the outlet field reads "1 Manway / Lid", which names an opening and not a pipe size, and the inlet field is blank. No outlet dimension, thread, flange or valve appears on this sheet, so none is claimed. Tell us the duty and the line size you need and we will confirm what this part number carries before the pump is specified.
• The space between the walls: no monitoring port, gauge or alarm is published. Whatever arrangement you want for watching that space is specified separately, and it is worth specifying, because the whole value of a second barrier is being able to show it is still empty.
• Structure: the sheet publishes no lifting lugs, no ladder lugs and no flange lines on this part number.
• Level: no gauge, sight tube or graduation is published on the sheet. Decide how the level will be read before the tank is set rather than afterwards.
• Limits: 120 F / 48 C, a specific gravity rating of 1.9, and a 3 Year Warranty. That is the whole of what this sheet publishes about service.

Name the product and its strength when you order. The lid seal, any fitting we add and the pump arrangement are all chosen against that chemistry, and on a contained tank the fitting is the one part of the system that a second wall does not protect you from.

Acid feed rooms with a floor to protect

A hundred and fifty gallons with containment built in is a point-of-use quantity: a chemical feed or dosing room at a small water or wastewater works, a treatment skid in a food, beverage or dairy plant, a boiler house or cooling tower station, a pool and aquatics plant room, a laundry or vehicle wash, a plating and metal finishing shop, and pilot or laboratory work standing on a finished floor. What those sites share is a room with no space for a built bund and a floor where a release would go somewhere expensive, and this vessel answers both at once with one item, one footprint and nothing to construct. Build one habit from the first week. Look into the space between the walls on a fixed schedule, write down the date and what you saw, and keep that record with the tank rather than in somebody's head. A second barrier is worth exactly what your evidence says about it, and the site that can produce a dated log is the site that never has the difficult conversation.

A hundred and ten pounds, class 250, one pallet

Marked Tree, Arkansas is the plant and Arkansas the only ship-from state. Freight is LTL at class 250, the sheet lists no NMFC number, and the shipping size is given at 34 by 34 by 62 inches at 110 pounds. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. This is a single pallet position and a tail lift delivery on most routes, so no crane, no dock appointment and no hired equipment, but measure the door height on the way in before the truck is booked. Take it under the base with a pallet truck or forks, never by the lid. Set it in its final position on the finished, level surface before anything is plumbed in, then fill it with clean water and hold that 1,251 pound load while you read the lid seal and the base all the way round. Drain it, let it dry, and then open and look into the space between the walls before the working product ever arrives, recording the date on the shell in paint marker. That first look is the baseline every later inspection gets compared against. Put the part number on the maintenance log the same day, because five years on nobody remembers which of the four shells this one is. Write the fill date on the manway with a paint marker; it answers the first question anyone asks about a tank.
