2500 Gallon 30 Degree Crosslink Cone Bottom Tank

The one row in this family whose material field is not plain polyethylene

Take the family first, because it is what this part number is for. The sheet lists several 2,500 gallon cone bottom tanks on the same 90 by 90 by 125 inch shell, and on the rows beside this one the material field reads polyethylene. On this row it reads Cross Linked Polyethylene. That is the published difference and it is the only one this page will draw, because the sheet offers no wall thickness, no layer count and no construction note to go with it, and a difference that is not published is not a difference we will sell you. Where the material line matters is chemistry duty: cross-linked walls are specified for service that a maker will not put a plain polyethylene wall into, and a specifier who has been handed that requirement already knows it. Where it does not matter, this is a more expensive way to hold the same 2,500 gallons and the plain polyethylene rows beside it do the same job. Bring us the product and we will tell you honestly which side of that line you are on. The second half of the family question is the rating, which on this listing is a specific gravity of 1.5 with 31,275 pounds of max contents against 20,850 pounds of water in the same 2,500 gallons. That covers water, treated water and the ordinary run of process liquid no heavier than water, and it is the sensible pairing with a tall shell. The colour field reads White, so daylight reaches the contents and an operator gets a rough level by eye from the floor; on chemistry duty that is a housekeeping question worth asking before the tank goes outdoors. Last comes the structure, and it is not optional. A cone bottom tank has no flat floor and cannot stand on its own bottom. This sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so the support is a separate item with its own drawing and its own lead time, and no stand height, rated load or material is stated on this page. It carries 20,850 pounds of water and up to 31,275 pounds at the rating, with 125 inches of shell above it, all landing on a few feet inside a 90 inch circle. Fix the volume with the tank sizing calculator and take the freeboard from the tank sizing guide before the support is drawn.

Three more listings on this shell, a step down and a step up

The top four rows are one shell at 2,500 gallons, 90 inches across and 125 inches tall, listed several ways. The weight column is where this sheet contradicts itself and we print it rather than tidy it: the empty weight on this listing reads 4 pounds and the shipping weight reads 375 pounds. The sibling rows read 375 pounds and 400 pounds. No page here reconciles those figures or explains them, because the sheet does not, and a number we cannot stand behind is worse than a blank. What you can plan against is the shape and the rating, and both are unambiguous. The two rows at the bottom are the size ladder, and the useful thing about them is that all three capacities sit on the same 90 inch circle: 2,000 gallons at 102 inches, 2,500 gallons at 125 inches and 2,600 gallons at 139 inches. Move up or down that ladder and the pad, the bund and the aisle stay as drawn; only the headroom changes. Decide the circle once, measure the height you have, and the capacity follows. If this exact size is the decision in front of you, the complete buyer's guide to a twenty-five hundred gallon thirty degree cone bottom tank walks the whole selection rather than one part number, and if the angle rather than the volume is the open question, the cone angle selection guide sets the shallow, middle and steep options against the way real product drains.

Top access only, and one opening dimensioned

• Start at the lid, because it is the only opening this sheet dimensions: an 18 inch threaded vented manway, with the lid size field also reading 18 inches. The vent arrives with the manway rather than as a separate specification, and that air path is what keeps the wall out of trouble while a pump draws the tank down. Keep it clear, check it whenever the tank is opened, and never blank it to control a smell.
• The height to it: 125 inches of shell plus whatever stand carries the tank, which is the tallest column in this group. This sheet counts no ladder lugs and no structural attachments, so plan the access with the structure and land the fill at a coupling at working level rather than at the top.
• The outlet: none is published on this sheet, and neither is an inlet. No discharge size, thread, bulkhead or valve is stated or implied here. Tell us the line size, the valve type and the product, and we will confirm what this part number carries before it is ordered.
• Under the cone: 30 Degree is the maker's name word and no cone angle field appears on the sheet, so no measured angle is claimed. The load path is not in doubt, though. Everything hung at the low point holds the column above it, up to 31,275 pounds at the rating, so carry the valve, any reducer and the first pipe run on steelwork off the stand rather than on the tank, with a flexible connector at the first joint.
• Not published: a service temperature limit, a warranty term, an NMFC number, a lug count, a flange count and any stand detail. None is claimed anywhere on this page. Published: the material field reading Cross Linked Polyethylene, a rating of 1.5, 20,850 pounds of water at 2,500 gallons and 31,275 pounds of max contents.
• Gaskets and trim follow the chemistry, not the tank. A cross-linked wall does not make a wrong gasket right, and on chemistry duty the fitting selection is where installations fail first.

Because no service temperature is published on this sheet, treat a hot fill as a question to ask rather than an assumption to make.

Aggressive process liquid held at twenty-five hundred gallons

The material field is why this part number gets specified, so the duty list follows it. Treatment chemistry held at working strength at a water or wastewater works, process liquor and spent solution in a metals or plating shop, concentrated mineral and salt solutions in manufacturing, crop input concentrate at an agricultural retailer, and intermediate holding between two stages that run at different rates. In every one of those the specifier has usually been handed a material requirement by somebody else, and the honest service is to match it rather than to argue with it. What the shape adds is the drain: 2,500 gallons that gives all of itself back at the changeover instead of leaving a layer on a floor, which on chemistry duty is a rinse rather than a recovery job and a real reduction in what has to be handled by hand. The tall column is the trade. At 125 inches of shell on a 90 inch circle you buy floor area cheaply and pay for it in height, in ladder work and in a liquid that stratifies more readily than a wide shallow vessel would. If the blend wants to separate, plan the draw point and the mixing arrangement with the tank. Two limits are worth saying plainly: this sheet publishes no service temperature figure, and it publishes no outlet, so the fill temperature and the discharge arrangement are both conversations to have before the order rather than after the truck. Check the product in our chemical compatibility reference first, and bring us the concentration and the temperature with it.

Two weight figures on one sheet, and a class fifty ticket

This tank is moulded at Lincoln, Nebraska, and Nebraska is the origin state on the sheet, so the Midwest and the plains are the short lane and both coasts are the long one. The freight paperwork on this listing is the oddity of the batch and we print it as it reads rather than smoothing it: the freight class reads 50 with no ship mode given, where the listings beside it read class 500 beside an oversize mode, and no NMFC number is published anywhere on the sheet. The weight reads two ways as well, 4 pounds empty and 375 pounds shipping. Because of that, do not price this lane from the page: run your own ZIP through the freight cost estimator and let us confirm the ticket with the carrier before you budget. The listed price is before freight. The package measures 90 inches by 90 inches by 125 inches, which is a tall, light load that pays for the space it occupies on the trailer. It travels lying down and is stood up at your end, so agree who is doing that and with what before the truck is booked; the sheet publishes no crane, no rigging, no permit and no escort detail, and none is described here. Have the support set, levelled and anchored first. No lifting lugs are counted on this sheet, so sling under the body rather than off the manway, and restrain the shell as soon as it is vertical. Commission with clean water before any product goes near it: hold the 20,850 pound water load, walk the manway seal, the cone joint, the stand feet and the pad edge with a torch, and leave it standing full overnight. Photograph the discharge area from below before any pipe goes on; a slow weep is far easier to compare against a picture than to describe over a phone. Tape a copy of the spec sheet inside the control panel door; the next person to touch the tank will not have the box it came in.
