Snyder Industries 330 Gallon HDPE Vertical Liquid Storage Tank with ASTM Certification

Certified, low and wide

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 covers the D1998 sizing logic and the headspace where a wall gives out first. A 44 inch base under 58 inches cannot tip, so the tank needs no strap, and the 18 inch manway admits a fill hose, a float switch and a level sender at once. Full, it puts 5,229 pounds on a 44 inch circle at the rating; a paver pad or a full-contact slab takes that load, and the concrete pad sizing guide covers a shared slab. The tank sizing calculator turns feed rate and refill schedule into a tank size, and the tank sizing guide covers the reserve.

Snyder's 300 to 360 gallon squat verticals

The 1630300N45 is the heavy-wall certified 330, 20 pounds heavier on a base 4 inches wider and 3 inches shorter. The 1008200 tanks are the general 330 on a 47 inch base at 50 inches, with the N42 in cross-linked polyethylene for oxidizers. The 1011200C26 is the doorway shape at 300 gallons, and the 5760100N42 is the cross-linked 360 on a 53 inch base.

Outlet and manway

• Access: 18 inch threaded, vented manway at chest height; a dip tube takes the fill from a hose or tote pump; a fuming liquid gets a vent line to the outside.
• Outlet: tell us the liquid when ordering and the bulkhead fitting is matched to it; a short flexible section to the pump, and the valve supported on its own bracket.
• Service limit: 120 F / 48 C.
• Listing: ASTM certification.

A white tank shows its level in daylight; a low-level float switch keeps a pump from running dry. 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. At changeover the manway is a hand's reach from the floor of the tank, so a wash-down wand cleans it without anyone leaning over an opening.

Who buys this tank

Treatment chemicals at a small system that needs the certification on file and has a low ceiling, brine for a softener, 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.

Delivery day

The 1011600N45 ships palletized as LTL freight (NMFC 156600-02) at a class rate; the freight cost estimator shows it for your ZIP, and the listed price is before freight. One person carries 80 pounds. Water-fill to the manway and hold it, check the outlet fitting, and keep the certification paperwork with the project file. Keep the delivery paperwork with the tank; the serial number on the shell is what a warranty claim starts from.
