Snyder Industries 710 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Certified, low and wide

Seven hundred ten gallons is three totes with a margin, and a 60 inch base under 68 inches holds it under a mezzanine or a low pipe rack where a tall tank of the same volume would not. The certification is against ASTM D1998, the standard rotationally molded polyethylene tanks are specified to, and the way a tank meets it is in the wall; the HDPE tank wall thickness guide walks through the D1998 sizing logic and why a wall fails first in the vapor headspace. Full, it puts 11,251 pounds on a 60 inch circle at the rating; a slab in full contact carries that, and the concrete pad sizing guide covers a shared slab. The tank sizing calculator sizes the tank to feed rate and delivery interval, and the tank sizing guide covers the reserve.

Snyder's 550 to 750 gallon squat verticals

The N42 is cross-linked polyethylene for oxidizers and the N48 is another linear grade, both at this tank's weight in the same shell. The 1800000C34 is the 550 gallon doorway tank on a 48 inch base, and the 5990900N42 lays 750 gallons down to 66 inches on a 68 inch base in cross-linked resin. The 5990902N45 is the double wall at 750 gallons for a site with no spill pallet or berm.

Openings as shipped

• Access: 18 inch threaded, vented manway, a short step up; filled by hose or tote pump through a dip tube, vented outside on anything that fumes.
• Outlet: the bulkhead fitting is chosen for the liquid at order time; a flexible connector to the pump suction, with the valve carried by a bracket rather than the fitting.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

A white tank shows its level in daylight; fit a low-level float switch so a pump never runs dry. The dosing pump sits below the outlet so it primes by gravity, the manway stays closed against vapor loss, and a light-sensitive chemical stays out of the sun. At changeover the manway is a short reach from the floor of the tank, so a wash-down wand cleans it without anyone leaning far over an opening.

In service

Treatment chemicals at a small system that needs the certification on file and has a low ceiling, brine for a softener bank, acid and inhibitor feed at a cooling tower, polymer make-down on a skid, and, with water in it, a well buffer or a cell of the small fire reserve the fire-water reservoir design guide describes. One liquid per tank, labeled.

Freight and unloading

The 1700200N45 ships palletized as LTL freight (NMFC 156600-02) at a class rate; the freight cost estimator shows the lane to your ZIP; the listed figure is the price before freight. A pallet jack moves 185 pounds, and at 60 inches across it needs a wide door. Water-fill to the manway and hold it, check the outlet fitting, and keep the certification paperwork with the project file. The first fill is the only cheap time to find a problem, so do it in daylight with someone watching the base.
