Snyder Industries 3500 Gallon ASTM Black Captor Double Wall Tank

Black wall, 120 F sheet, and who that suits

Against the other listings on this 158 inch shell, two fields make this one what it is. The colour field reads black where its cross-linked shellmates read natural white, and the material field reads high density linear polyethylene where those shellmates read crosslinked linear polyethylene. Its service limit is 120 F / 48 C. Everything else is held in common with the heavier listings in the group: 3,500 gallons, 102 by 102 by 158 inches, 2,500 pounds empty, a specific gravity rating of 1.9, and 55,461 pounds of maximum contents against 29,190 pounds of water. So the case for this part number rather than 5600000N42 is a case about light and about the maker's own naming, not about strength or size, which are identical. Take the light seriously, because it is the difference you will live with. A black wall keeps daylight out of the contents, which matters to any product that degrades in sunlight and to any tank standing outdoors in an open yard where nothing shades it. That is the whole argument for black in this family and it is usually decisive when the tank is going outside. What you give up is the one free instrument a white tank hands you: on a natural white shell an operator can often read the level through the wall in good light, and on this one they cannot, so a level arrangement stops being optional and becomes part of the specification. Decide that before the tank is set, not after the first time somebody guesses wrong. The other half of the decision is the limit. At 120 F / 48 C this sheet is not the one to choose for genuinely warm service; a cross-linked listing in the same shell publishes a higher figure and that is the row to look at instead. Tell us the product, the strength and how warm it runs, and we will confirm which of the codes Snyder names for it. The site work is identical across the family. Thirteen feet of tank on an eight and a half foot square plan wants a flat, continuous, level surface carrying the whole footprint, never rails, never a shim at one corner, because 29,190 pounds of water sits on it; the concrete pad sizing guide for above-ground polyethylene tanks gives the framework and its boundary. Settle the volume you can actually use with the Captor double wall freeboard sizing guide, then check quantity and turnover in the tank sizing calculator and take the freeboard discipline from the tank sizing guide. Outdoor tanks make the headspace the hardest-worked part of the wall, so the wall thickness at the vapour saturated headspace guide is worth reading before you write the inspection routine, and where containment is being bought for a regulatory reason the Captor double wall compliance walkthrough takes the requirements in order.

The same eight and a half foot plan under four names

Four rows share this exact 158 inch shell and three of them, including this tank, are listed at 2,500 pounds against 2,100 for the lighter code. Outside dimensions, capacity and the specific gravity rating are common to the heavier listings; the names, the material fields, the colours and the service limits are where they part company, and the sheet explains none of it. We print it as given. What we will do is match your duty to the code Snyder names for it, which is a conversation about the product and the site rather than a table exercise. The size rows behave the way the whole family behaves: everything sits on the same 102 inch square, so gallons cost height and nothing else. 5590000N30 is 3,000 gallons at 142 inches and 1,900 pounds; 5610000N30 is 4,000 at 178 inches and 3,200 pounds. On a black tank going outdoors that has one extra consequence worth thinking about, because height and exposure travel together. A taller vessel in an open yard presents more surface to wind and more ladder to climb in bad weather, and every inch above the manway has to be reachable safely in January as well as in June. So on an outdoor installation, pick the shortest row that fits your delivery interval rather than the tallest row that fits the site, and spend the difference on the access arrangement.

The manway vent and the light the wall keeps out

• The vent: the 18 inch manway is listed as threaded and vented, and outdoors that path also has to survive weather, insects and freezing. Keep it clear, inspect it every time the manway is opened, and never blank or restrict it; a tank standing in an open yard breathes with the sun as well as with the pump.
• The opening: 18 inches is the only opening the sheet publishes, serving as the fill point, the inspection hatch and the cleaning access at once. Plan everything that has to happen on top around one hole before the tank is set.
• Access: the manway is at 158 inches. Outdoors that means a fixed ladder, a platform and fall protection designed with the installation and specified for wet and icy conditions, not a stepladder carried out on the day.
• Level: the wall is black, so nothing can be read through it. A sight arrangement, gauge or level instrument is a specification item on this listing in a way it is not on the white shellmates; decide it before the tank arrives.
• The outlet: the outlet field reads "1 Manway / Lid", an opening and not a pipe size, and the inlet field is empty, so no outlet dimension, thread or valve is claimed here. Tell us the duty and the line size and we will confirm what this part number carries.
• The space between the walls: no monitoring port, gauge or alarm is published on this sheet, so how that space is watched and recorded is specified separately.
• Limits: 120 F / 48 C, a specific gravity rating of 1.9, and a 3 Year Warranty.

Name the product when you order, and specify the level arrangement in the same breath; on a wall you cannot see through, that instrument is the difference between a controlled fill and a guess.

Outdoor and daylight installations at thirty-five hundred gallons

A black contained tank at this size is bought where the vessel stands in the open and the contents care about light: agricultural retail and crop input storage, outdoor chemical compounds at treatment works, mine site and quarry water treatment, transport depot and fleet wash installations, outdoor dosing at industrial plants, and any yard where the alternative was a tank in a built bund exposed to the same sun. It is also the sensible choice on any roofless pad where a white shell would grow algae in a stored water duty. What the second wall buys you outdoors is specific: a release that reaches a yard surface reaches a drain, and a drain reaches something that costs real money to put right. Build two routines around it. Inspect the space between the walls on a fixed schedule with the date written down, and walk the vent and the top arrangement after every hard freeze and every storm, because outdoors the fittings weather long before the shell does. Where the reason for a large outdoor vessel is private fire water storage rather than chemical holding, that is a different duty sized by different rules and the fire water reservoir design guide for rural and remote sites is where that enquiry starts; nothing on this page is a claim about that use.

Two and a half thousand pounds on a wide pallet

The plant is Lincoln, Nebraska, and the sheet lists two ship-from states, Nebraska and West Virginia; both are printed as the sheet gives them. Freight is LTL at class 250 with no NMFC number, and the load is 102 by 102 by 158 inches at 2,500 pounds. Price the lane to your ZIP with the freight cost estimator; the listed price is before freight. An outdoor installation usually makes the delivery easier, because the tank can often be set close to where the truck can stand, but measure the route anyway: eight and a half feet square does not corner between buildings and thirteen feet of height finds overhead lines nobody remembers until the day. Take it under the base, never by the manway. Set it on the cured, level surface in its final position, prove it plumb in two directions, and secure the surround before anything is plumbed in. Fill with clean water, hold the 29,190 pound load, and read the manway seal and the whole base line while it is under load. Drain it, let it dry, open the space between the walls and record that first inspection on the shell. Then stencil the contents and the fill date on the black wall in a paint that stays readable in sunlight, because an unlabelled black tank in a yard is the one somebody eventually connects the wrong hose to. Check the strap tension a week after the first fill; a tank settles a little, and the strap that was tight is loose.
