A 12500 gallon black XLPE double wall tank for warm liquids near water weight
Snyder part number 1031100N46 is a 12500 gallon double wall tank in black crosslinked linear polyethylene: an inner tank inside an outer containment shell, so the tank carries its own secondary containment. It is 142 inches in diameter, 274 inches tall and weighs 8,500 lb empty. On top is an 18 inch threaded vented manway. The wall is rated for liquids up to 1.5 specific gravity with a service limit of 140 F. 12500 gallons of water weighs 104,250 lb; at the full 1.5 rating the contents can weigh about 156,400 lb. Snyder backs it with a 3 year warranty. Black keeps light off the contents.

Where it goes
The 140 F limit and the 1.5 rating point this tank at liquids close to water in weight that are stored or received warm: wash and rinse supply, boiler and cooling tower make-up, dilute process solutions in a hot building, and bulk storage on any site where a release must stay off the ground. If your liquid is heavier than 1.5 times water, ask us for a version with a higher rating. The pad is a civil job at this size: about 156,400 lb on a 142 inch circle wants a designed, cured, level slab. Indoors, measure 274 inches plus a platform above the manway. Warm liquids expand, and a contained tank gives less usable volume than its nameplate once freeboard is allowed for; our Snyder double wall freeboard sizing guide works that through, and the tank sizing calculator and tank sizing guide cover turnover. The headspace wall thickness guide explains why inspection starts at the vapour line. For a fire protection reserve, read the fire water reservoir design guide first.
Openings, and what to confirm before you buy
- Manway. One 18 inch threaded vented manway on top: fill point, inspection point and vent in one. A warm headspace moves more air as the level changes, so never restrict the vent. At 274 inches the tank needs a fixed ladder or platform with fall protection.
- Outlet. No outlet or fitting is listed on this product. Tell us the line size, valve and pump arrangement and we will confirm with Snyder what this part number carries.
- The liquid. Give us the chemical, its concentration and its working temperature. Gaskets and valve seats are chosen against temperature as well as chemistry.
- The space between the walls. No leak detection is listed with the tank. Specify it separately and inspect on a written schedule. Snyder's drawing is linked under Technical Drawing on this page.
Other 12500 gallon versions, and one size down
Snyder sells this 142 inch body under several part numbers that differ in resin and rating rather than size: the 12500 gallon XLPE double wall tank 1031100N40, the 12500 gallon HDPE double wall tank 1031100N45 and the 12500 gallon sulfuric acid double wall tank 1031100N30; each page states its own rating. One size down is the 10000 gallon sulfuric acid double wall tank 1006600N30. Order by part number, since names repeat across versions.
Shipping and receiving
The tank ships LTL at freight class 250 from Snyder's Lincoln, Nebraska plant, 142 by 142 by 274 inches at 8,500 lb. A load this size may be routed to us by phone rather than priced online; call if the estimator sends you there. Plan the route, the crane and the set position before it leaves the plant, and lift from the base, never by the manway. Set it plumb on the cured slab, fill it with water and hold the 104,250 lb load while you check the manway seal and the base. Drain, dry, inspect the space between the walls and write the date on the shell. At the tailgate, check the bill of lading against 1031100N46.
