Snyder Industries 5000 Gallon ASTM XLPE Black Double Wall Tank

Warm and dense at five thousand gallons, on a pad that has to be flat

Where this vessel stands does more work than any other decision around it. The plan is a 102 inch square and the column is 216 inches, so eighteen feet of tank bears on eight and a half feet each way, and the sheet gives 41,700 pounds of water at capacity with 79,230 pounds of contents at the published rating. Put that on a slab that is level, continuous and fully cured across the entire footprint, with no rails, no shims and no packed corner, and confirm it with a level on both diagonals before delivery day. Put it on anything less and you own a lean for the life of the installation. Then look up: the only opening on this sheet is at the top of the column, so a ladder, a platform, fall protection and the fill arrangement all have to fit above the shell at the position you have chosen, and the clear height is measured to the lowest service in the way rather than to the roof steel. The pair of numbers that make this row the right one are on this sheet and nowhere else. The service limit is 140 F / 60 C, which is what you hold against the real worst case: a solution held at temperature, a product that comes off the tanker warm, a bay under a steel roof in August. The rating is a specific gravity of 1.9, carrying 79,230 pounds of maximum contents against 41,700 pounds of plain water at 8.34 pounds per gallon, which is wall listed for something appreciably denser than water. Warm and dense together is what this listing answers, and if your duty is only one of the two you are buying more than the job needs. The material field reads crosslinked linear polyethylene, and that is the whole of what this page will say about resin, because a resin word is not a compatibility statement and no sheet here offers an interpretation of one. Colour is black, which keeps daylight off the contents and removes any chance of reading a level through the wall, so the level instrument belongs on the specification. Before the capacity is fixed, work out what you can really use: the Captor double wall freeboard sizing guide covers thermal expansion, chemistry and density, and warm duty is exactly where that matters. Then check quantity and turnover in the tank sizing calculator and the tank sizing guide.

The 216 inch column and the shorter rows beside it

Four part numbers share this exact 102 by 102 by 216 inch shell, and the sheet separates them by listed weight alone: this tank and 5630000N42 at 4,300 pounds, 5630000N40 and 5630000N46 at 3,600. It does not say why, and inventing a reason would be worse than leaving the question where it belongs, which is with the product you are storing and how warm you run it. Where a drawing or an existing installation already names one of these part numbers, order that one and we will confirm the published figures before anything ships. What the table settles cleanly is the shape question. Every row that keeps the 102 inch square changes only in height: 197 inches for 4,500 gallons at 3,800 pounds, 216 for this tank's 5,000. The one row that changes the plan, 5,500 gallons on a 120 inch square at 172 inches and 3,200 pounds, gives you more volume in a much shorter package and takes eighteen inches of floor in each direction to do it. So the decision is made with a tape measure at the actual position: free floor first, then clear height with the platform allowed for, then the delivery interval you are willing to live with.

Outlet, manway and vent on an eighteen foot column

• The outlet field: it reads "1 Manway / Lid" and the inlet field is empty. That names an opening rather than a pipe size, so no outlet dimension, thread, flange or valve is claimed here. Tell us the duty, the working temperature and the line size and we will confirm what this part number carries before pipe is bought.
• Designing around one opening: the discharge path is specified with us rather than inferred from the listing. On a tank configured this way the common answer is a suction line dropped through the manway to a pump beside the vessel, its foot set clear of the bottom so settled material stays where it is.
• Warm duty at the pump: the sheet lists 140 F / 60 C, so seals, gasket material, valve seats and any flexible connection are chosen against temperature as well as chemistry. A warm-service weep almost always starts at a fitting, not at the wall.
• The manway: 18 inches, threaded and vented, eighteen feet up. Everything that has to happen on top happens through it, so the platform and the access arrangement are designed with the installation.
• The vent: part of the manway. A warm headspace moves more air for the same change in level, so never blank or restrict the path, and inspect it whenever the manway is open.
• Structure: this sheet lists 8 lifting lugs, ladder lugs and 4 flange lines.
• Level and prime: black wall, no visual level, one opening. The low level cut-out is chosen with the pump and the stop level is marked before the first fill.
• The space between the walls: no monitoring port, gauge or alarm is published on this sheet, so that arrangement is specified separately.
• Limits: 140 F / 60 C, a specific gravity rating of 1.9, and a 3 Year Warranty.

Name the product, its strength and its working temperature at order time, and every wetted part is chosen once against the real duty rather than replaced after the first warm summer.

Process chemistry that arrives warm and stays heavy

The combination on this sheet points at process plants rather than water works: concentrated treatment chemical holding at municipal and industrial water and wastewater sites, caustic and acid storage on process lines, plating and metal finishing, pulp and paper, mining and mineral processing, boiler house chemistry, and clean-in-place make-up in food, beverage and dairy plants where the solution is held at temperature. In every one of them the second wall is bought for the surface underneath, and the way it earns its keep is the record you keep of the space between the walls. Three pieces of reading belong with the order. The vapour line, not the liquid, is where a polyethylene wall works hardest, which the wall thickness at the vapour saturated headspace guide explains, and warm duty makes that more relevant rather than less. Where this is being compared against a buried steel double wall system, the cathodic disbondment testing guide for double wall interstitial spaces covers the coating adhesion problem that an above-ground polyethylene vessel avoids entirely. And where the enquiry is really about private fire water, the fire water reservoir design guide for rural and remote sites is the honest starting point; this page claims nothing about that use.

Eighteen feet of shipment, class 250, no NMFC number

This sheet names one plant, Lincoln, Nebraska, and publishes no ship-from state field, so the plant is printed and nothing else about the lane is claimed. Freight is LTL at class 250 with no NMFC number, and the shipping load is 102 by 102 by 216 inches at 4,300 pounds. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. No crane specification, rigging plan, permit or escort requirement is published on this sheet, so none is stated; the sheet does list 8 lifting lugs, and beyond that the lift is planned with the equipment you can actually source. Measure the route for the height rather than the weight. Eighteen feet of shipment on an eight and a half foot square clears a yard easily and stops dead at a door head, an overhead service or a low gate frame, so walk it once with a tape before the truck is booked. Take it under the base or from the published lugs, keep it upright wherever the route allows, and never let a sling sit on the manway. Set it in its final position on cured, level ground, prove it plumb in two directions while empty, then water test it and hold 41,700 pounds while you read the manway seal, the base line and the pad. Drain, dry, open the space between the walls and look in good light. Write the date, the part number and the contents on the shell in paint marker, and put the delivery paperwork where the next person will find it, because the serial number on the shell is what a warranty claim starts from. The first fill is the only cheap time to find a problem, so do it in daylight with someone watching the base.
