Snyder Industries 1250 Gallon XLPE Heavy Duty Cone Bottom Tank

The smallest shell on this sheet, and the two sizes above it

Four part numbers share this shell and every measurable figure on it: 1,250 gallons, a 95 inch circle, 70 inches of height, 300 pounds empty, a specific gravity rating of 1.9 and 19,808 pounds of max contents. Only the colour field moves between them, so within the group the choice is simply whether daylight should reach the contents. This row is the natural white one, which lets an operator read roughly where the level sits through the wall in daylight, from the floor, on a tank only 70 inches tall. On a vessel that gets checked a dozen times a shift that is a practical advantage rather than a specification line, and it is the reason to take this row over the dark ones. The more interesting question is the one the family asks going up rather than across. This sheet also lists a 1,000 gallon shell and a 1,400 gallon shell, both on an 86 inch circle, and both are narrower than this one. So at the small end of the range the capacities do not stack on a single circle the way they do further up: moving between 1,000, 1,250 and 1,400 gallons changes the footprint as well as the volume, and the pad, the bund and the stand change with it. Work out the real batch before choosing, because there is no free upgrade path here. The support is a separate item as it is on every cone. This tank has no flat floor, cannot stand on its own bottom, and the sheet publishes no stand, no legs, no skirt, no support ring and no bolt pattern, so no stand height, rated load or material appears on this page. What it has to answer is 300 pounds of empty tank, 10,425 pounds of water and up to 19,808 pounds at the rating, arriving through a handful of stand feet inside a 95 inch circle rather than spread across a slab. Size the volume with the tank sizing calculator, take the freeboard from the tank sizing guide, and settle the support against the cone bottom tank stand compatibility matrix before either is ordered.

One 70 inch shell listed four ways, plus a 1000 and a 1400

The top four rows are one tank in four colour fields, so the group asks you one question and then gets out of the way. The bottom two are the size decision and they behave differently from the larger families in this range. 1890000N42 holds 1,000 gallons on an 86 inch circle at 66 inches, and 1900000N42 holds 1,400 gallons on the same 86 inch circle at 80 inches, so those two share a footprint with each other but not with this tank. Moving from 1,250 gallons to either of them is a change of circle, which means a change of pad, a change of stand and a change of whatever bund or kerb sits around it. Get the batch size right first, because at this end of the range there is no stepping up later without redrawing the ground. Where this shell wins is height and handling: at 70 inches it is the lowest of the three, everything on it is reachable from the floor once the stand height is known, and 300 pounds is a weight a small yard can manage without specialist equipment. Where it loses is floor, because a 95 inch circle is the widest of the three and it takes the most room in a bund. That is the trade in one line. If the crosslinked wall itself is what you are weighing rather than the shape, our read on XLPE against HDPE for chemistry duty sets out the duties where crosslinking changes the answer and the duties where it does not.

Height or floor the limit? The table has both shapes; freight to your ZIP is quoted on each row, or call 866-418-1777 with the site.

The 18 inch manway on a 70 inch tank, and the fields left blank

• The manway: 18 inches, threaded and vented, and on a 70 inch shell it is the lowest lid in this batch once the stand height is known. That one fact changes how a tank gets looked after, because a lid you can reach is a lid that gets opened, checked and closed properly rather than left for the next shutdown.
• The vent: it comes with the manway on this sheet rather than as a separate item, and it is what protects the wall while a pump draws the tank down. Keep the path clear, check it every time the tank is open, and never blank, paint or tape it to control an odour.
• The outlet field: it reads 1 Manway / Lid. That names an opening and not a discharge, and we print the field exactly as it reads rather than converting it into a pipe size. No outlet dimension, no thread, no bulkhead and no valve is published or claimed here. Tell us the line size, the valve type and the product and we will confirm what this part number carries before anything is ordered.
• Below the cone: the valve, any reducer and the first run of pipe belong on their own steelwork off the stand, never on the tank, with a flexible connector at the first joint so pump vibration stays out of the wall. The sheet allows the column above that joint to reach 19,808 pounds.
• The cone angle: this sheet publishes none and the product name carries none, so none is stated here and none should be read off a photograph. Ask us to confirm the geometry against the part number if drainage behaviour is what decides the purchase.
• Structural detail, inlet, lid size, warranty and NMFC: no lug count, no flange count and none of the other four appears on this sheet, and nothing is claimed. Published: a specific gravity rating of 1.9, 10,425 pounds of water at 1,250 gallons, 19,808 pounds of max contents and a limit of 100 F / 37 C.

Even a translucent wall is only readable in decent light and from the right side of a building, so choose the instrument deliberately with the level gauge selection guide for chemical service, which compares radar, ultrasonic, hydrostatic and magnetostrictive on the ways each one fails. Where the tank stands over ground or a floor that would have to be recovered after a release, the Captor containment comparison answers containment separately from the tank itself.

Small batch duty with a product heavier than water

Twelve hundred and fifty gallons is a working size rather than a storage size, and the 1.9 rating tells you what it is working with. Concentrated crop inputs and treatment chemistry at strength, brines and mineral solutions, spent liquor and recovered process liquid, polymer and coagulant make-up at a small works, batch preparation in manufacturing where the recipe changes weekly, and day tank duty feeding a pump from a reserve that gets refilled often. The 19,808 pound allowance against 10,425 pounds of water is what makes a dense product ordinary here instead of marginal, and the cone is what stops the heaviest fraction of it becoming next week's problem: dense residue on a flat floor is heavier, more valuable and more expensive to dispose of than a light one. The low, wide shell is the practical half of the argument. At 70 inches this tank is worked on from the ground, fits under mezzanines and low roof lines, and does not need an access platform drawn around it. The natural white wall adds the daily convenience of a level you can see without an instrument, which on a small batch tank checked repeatedly through a shift is worth more than it sounds. One caution belongs with it: a translucent wall lets daylight into water-based product, which is a housekeeping question outdoors and no question indoors. Look your liquid up in our chemical compatibility reference before the trim is specified, because the chemistry decides the gasket and the valve rather than the vessel.

Three hundred pounds, class 400, Marked Tree origin

Marked Tree, Arkansas is where this one is moulded, and the sheet gives Arkansas as the state it ships from, which puts the mid-South and the lower Midwest on the short lane. Check that against your own ZIP before comparing part numbers, because the tanks in this range leave from more than one part of the country and on a light bulky load the lane is a real part of the decision. The freight class reads 400, a numeric class beside an LTL ship mode, and no NMFC number is published. The package measures 95 inches by 95 inches by 70 inches at 300 pounds, wide and low, which is the easiest shape in this batch to get off a trailer and the one that needs the most clear ground to turn. Get the lane figure from the freight cost estimator; the listed price is before freight. The sheet publishes no crane, no rigging, no permit and no escort detail, and none is described here; agree the offload arrangement and the delivery window with us before the truck is booked. Have the stand set, levelled and anchored first. This sheet counts no lifting lugs, so lift under the body rather than off the manway, and keep the tank restrained once it is upright. Commission with clean water rather than product: hold the 10,425 pound load, walk the manway seal, the cone joint, the stand feet and the ground around the pad with a torch, and leave it standing full overnight before anything is connected. Because this is the small tank in a family that steps up by changing circles, note the pad dimensions and the outlet height on the site plan while the tape is out; if the duty ever grows, that sketch is what the next drawing starts from. The vent screen is the cheapest part on the tank and the one that saves it; look at it every time the manway opens.
