The 7400 Gallon Heavy Duty Cone Bottom Tank from Snyder Industries is a 1.9 specific-gravity polyethylene vessel built for full-drain bulk chemical service. At 142 inches in diameter and 160 inches tall, it holds 7,400 gallons and is rated to carry up to 117,260 pounds of contents at full capacity. The cone bottom self-drains, which is what separates a real chemical-feed or settling tank from a flat-bottom water tank where solids and heel liquid stay behind. If you have been searching for a heavy-duty cone tank or a large Snyder cone bottom for bulk storage, this is the high-SG end of that family.
Will it work for your application
The 1.9 specific-gravity rating is the constraint that governs this tank, and it ties directly to the weight numbers. Specific gravity is the weight ratio of your liquid to water, so a 1.9 rating means the tank is engineered for liquids up to 1.9 times the density of water at full volume. Plain water (SG 1.0) in this tank weighs 61,716 pounds when full; multiply by 1.9 and you reach 117,260 pounds, which is exactly the max rated contents weight. In other words, at SG 1.9 and full volume you are already at the design limit, not below it, so anything denser than 1.9 has to run at reduced fill. The footprint is 142 inches in diameter, so plan your pad and containment for that circle plus working clearance. Because this is a cone-bottom vessel, it needs a support stand sized to the loaded weight, and the outlet at the cone apex should be sized to your fluid's solids content. Our cone-bottom outlet sizing guide walks through whether the cone empties or plugs for high-solids versus low-solids service, and the Tank Sizing Calculator and Tank Sizing Guide help confirm 7,400 gallons matches your turnover. For top-side layout, the tank top fitting placement strategy guide covers vent, fill, and level layout, and the level gauge selection guide compares radar, ultrasonic, hydrostatic, and magnetostrictive measurement for chemical duty.
Chemical compatibility
This is a polyethylene tank rated to 1.9 specific gravity. The resin is recorded as HDLPE in our data, but the entry carries a question mark, so confirm HDLPE versus XLPE (cross-linked) with us before committing to chemical service, since the two resins differ in stress-crack and oxidizer resistance. That confirmation step is mandatory for the aggressive oxidizers below, where resin choice is the difference between years of service and early failure. The 1.9 SG rating means it can carry the dense liquids listed at the stated concentrations, with fitting and gasket materials matched per chemical. Always check the OEM chemical-resistance chart for your exact concentration and operating temperature before ordering.

For full per-chemical detail, see our Chemical Compatibility Database, and verify against the OEM chemical-resistance chart for your specific concentration and operating temperature.
The mistake to avoid
The costly error on a tank this size is matching the gasket and fitting to the wrong chemical. Sulfuric, hydrochloric, hydrofluoric, phosphoric, peroxide, and hypochlorite all call for Viton rather than EPDM; using EPDM on an oxidizing acid will degrade and leak. Peracetic acid is the outlier in the set: it needs Aflas (a different fluoroelastomer than Viton) on 316SS metal fittings, so do not substitute Viton or PVC there. DEF also moves to 316SS, and Propylene Glycol and Zinc Orthophosphate run on PP/316SS rather than PVC, so confirm the metal fitting where the pack calls for it. The second mistake is the resin question above: do not assume cross-linked construction. For the oxidizers in particular (sulfuric 98%, hypochlorite, peroxide, peracetic), confirm HDLPE versus XLPE before you order, because a high-SG rating alone does not guarantee long-term resistance to a given oxidizer.
