Snyder Industries 550 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Certified, and a size above the totes

Five hundred fifty gallons is two totes and a margin, the size a plant buys when tote handling has become the job, and a 48 inch base under 75 inches fits beside a dosing skid without a forklift aisle. 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 sets out how D1998 sizes a wall and why the headspace, not the liquid side, is where failures start. Full, it puts 8,715 pounds on a 48 inch circle at the rating, so it is strapped to a wall and set on a slab in full contact. The 550 gallon vertical tank buyers guide compares the shapes at this volume across makers; the tank sizing calculator sizes the tank to feed rate and delivery interval, and the tank sizing guide covers the reserve.

Snyder's 500 to 710 gallon verticals

The 1800000 tanks are the general 550 in this shell at 110 pounds, in three linear grades. The 5780100N42 is the cross-linked 500 for oxidizers, on a base 5 inches wider and 2 inches taller, and the 1700200N42 lays 710 gallons down to 68 inches on a 60 inch base in cross-linked resin.

Connections

• Access: 18 inch threaded, vented manway; fill by hose or tote pump down a dip tube, and vent to the outside if the liquid fumes.
• Outlet: tell us the liquid when ordering and the bulkhead fitting is matched to it; run a flexible line to the pump suction and hang the valve off the floor, not the tank.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

A white 75 inch tank shows its level in daylight; a float switch for low level protects a pump. Mount the dosing pump below the outlet so it primes by gravity, keep the manway closed against vapor loss, and keep the tank out of direct sun where the chemical is light-sensitive. A 48 inch tank fits a standard spill pallet, which is where a single wall chemical tank stands.

What it holds in practice

Treatment chemicals at a small system that needs the certification on file, 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.

Getting it to the pad

The 1800400N45 ships palletized as LTL freight (NMFC 156600-01) at a class rate; the freight cost estimator turns your ZIP into a freight number; the price on this page is before freight. Two people carry 130 pounds. Strap it, water-fill to the manway and hold it, check the outlet fitting, and keep the certification paperwork with the project file. Once it is full and holding, leave it alone for a day before the plumbing goes on; a settled tank is a quiet one.
