1. Industrial applications — an overview

General industrial tank duty splits into a handful of recognizable patterns. Process feed and day tanks stage chemistry inside production buildings: chemistry arrives by tanker or tote into a bulk receiving tank, gets dosed into a day tank for the production loop, and feeds the process at the metering pump. Wastewater pretreatment covers pH-adjustment caustic and acid feed tanks, polymer-emulsion flocculant tanks, ferric or aluminum coagulant tanks, and the holding tanks that buffer flow before discharge to municipal sewer or to the on-site wastewater treatment plant. Process water and rinse covers DI-water buffer tanks, rinse-water recovery tanks, and the recirculating tanks at metal-finishing and electroplating lines. Cooling tower and boiler chemistry covers the corrosion inhibitor, scale inhibitor, biocide, and oxygen scavenger feed tanks at the utility plant. Bulk acid and caustic storage covers the outdoor bulk farm where the receiving tanks and the secondary containment dike together hold the production-week chemistry inventory.

Each application carries a distinct duty cycle, temperature window, fill cadence, and regulatory exposure. The pages below explain the spec discipline that crosses applications, the resin-versus-chemistry compatibility matrix, the federal and state regulatory framework that governs general industrial tank service, and the procurement reality of buying tanks across the broad span of industrial process duty.

2. Why OneSource for industrial

Five OEM brands, one catalog. Norwesco, Snyder Industries, Chem-Tainer, Enduraplas, and Bushman cover the legitimate domestic plastic-tank market for general industrial service. We carry the full chemical-rated lines from each brand — Snyder Captor double-wall, Norwesco vertical chemical, Chem-Tainer ProChem, Enduraplas chemical-storage cones, Bushman bulk verticals — rather than carrying half a catalog from one brand. The procurement engineer compares HDPE 1.5 SG against XLPE 1.9 SG against the same chemistry on the same product page.

511-chemical compatibility database. Every chemical pillar in our reference library is sourced from manufacturer technical bulletins (OxyChem, Olin, Univar, Hawkins, K.A. Steel, Brenntag) and cross-checked against the resin compatibility charts published by the tank OEMs. We do not fabricate ratings. Borderline cases defer to the manufacturer chart and are flagged in the compatibility matrix for that chemistry.

50-state regulatory depth. Every U.S. state has a dedicated regulatory pillar covering bulk chemical storage rules: secondary containment thresholds, registration triggers, spill-reporting cadence, and the relevant agency. When the project sits in California, Texas, Florida, or any other state, the regulatory page for that jurisdiction is one click from this hub.

Custom fabrication when stock will not fit. Stock plastic tanks cover roughly 80% of industrial duties. The remaining 20% — high-temperature service, exotic chemistries, atypical footprints, integrated jacketing, alloy or lined-steel construction — route to our specialty & metal fabrication network for FRP, polypropylene, dual-laminate, alloy, and lined-steel custom builds.

Pricing transparency. Every product page lists a current price before freight. LTL freight to the destination ZIP is quoted separately through the freight cost estimator or by phone at 866-418-1777. List prices on this site exclude freight; nothing on this catalog ships freight-included by default. Listed at $X is the convention used across the catalog.

4. Chemical compatibility for industrial process chemistries

General industrial process chemistry covers the eight chemistries below as the highest-volume queries. Each pillar carries a full compatibility matrix (HDPE / XLPE / PP / PVDF / FRP / 316L / 304 / carbon steel / titanium / EPDM / Viton / Buna-N), real-world use cases, OSHA / NFPA / DOT / EPA hazard communication, storage protocol, operator FAQs, and a field-operations addendum on dosing accuracy and supply chain.

• Sulfuric Acid
• Sodium Hydroxide (Caustic)
• Hydrochloric Acid
• Sodium Hypochlorite
• Ferric Chloride
• Hydrogen Peroxide
• Phosphoric Acid
• Nitric Acid

The full chemical compatibility database indexes 500+ chemistries, including the polymer-emulsion flocculants, the metal-finishing bath chemistries, the semiconductor wet-bench process chemistries, and the mining-and-mineral-processing chemistries that span the broader industrial portfolio.

5. Regulatory considerations for industrial tanks

Industrial tank service touches OSHA general-industry rules, EPA RCRA waste-management rules, EPA NPDES wastewater-discharge rules, EPA SPCC oil-spill prevention rules, and the NFPA codes that govern flammable, combustible, and hazardous-materials storage.

29 CFR 1910 — OSHA general industry. The umbrella OSHA standard for general industry sits at 29 CFR 1910 and covers the subparts that apply to tank-related work: hazard communication (1910.1200), permit-required confined spaces (1910.146), control of hazardous energy (1910.147), personal protective equipment (1910.132 through 1910.140), and process safety management of highly hazardous chemicals (1910.119). Tank entry and tank-area work both touch the confined-space and lockout-tagout standards; the tank specifier should coordinate with the plant safety manager during commissioning.

40 CFR 264.175 — RCRA secondary containment. Hazardous-waste container storage areas require secondary containment sized to hold 10% of the aggregate volume of containers or 100% of the volume of the largest container, whichever is greater. The dike must be impervious to the stored waste and free of cracks or gaps. Plastic double-wall tanks (Captor, Bushman bulk vertical with secondary, Chem-Tainer ProChem secondary) satisfy this rule when sited indoors or in covered areas; outdoor bulk tanks typically rest in a poured-concrete or steel-plate dike with a chemical-resistant liner.

40 CFR 122 — NPDES wastewater discharge permits. The National Pollutant Discharge Elimination System governs point-source discharge to surface water (direct NPDES) and pretreatment discharge to municipal sewer (industrial pretreatment). Plants discharging process water (cooling tower blowdown, rinse water, scrubber blowdown) under an NPDES or pretreatment permit need holding-and-equalization tanks sized to the permit-defined sampling and discharge cadence. The plastic vertical and cone-bottom tanks in this catalog cover the day-tank and equalization-tank scale; bulk equalization basins above 50,000 gallons typically use FRP or steel.

40 CFR 112 — SPCC. Aggregate aboveground oil storage above 1,320 gallons triggers a written SPCC plan covering secondary containment, integrity testing, and personnel training. Industrial plants with bulk fuel oil, lube oil, or hydraulic oil aggregate above the threshold maintain SPCC.

NFPA 30 Flammable and Combustible Liquids Code. Bulk storage of Class IA, IB, IC, II, and III liquids is governed by NFPA 30. Polyethylene tanks are not approved for Class I flammable liquids; specifiers store flammable solvents in steel or FRP per NFPA 30 Chapter 21. Plastic tanks cover combustible (Class II / III) and non-flammable chemical service.

NFPA 400 Hazardous Materials Code. NFPA 400 consolidates the storage rules for oxidizers, organic peroxides, water-reactives, pyrophorics, and corrosives. Each hazard class has a maximum-allowable quantity per control area before sprinklers, hazard signage, and segregation distances apply.

ASTM D1998 — Polyethylene upright storage tank specification. The canonical specification for rotomolded polyethylene upright storage tanks. The standard covers wall thickness as a function of SG and tank diameter, the test methods for impact resistance and environmental stress cracking, and the documentation required from the tank manufacturer. Stationary storage tanks in the catalog are built to ASTM D1998.

State-level overlays sit on top of the federal rules; the relevant state regulatory pillar for the project location captures registration triggers, spill-reporting cadence, and any state-specific containment math. Those pillars are linked from our state regulations index.

6. Field handling and procurement

Resin selection by chemistry. HDPE (1.5 SG, linear polyethylene) handles the bulk of industrial chemical service at ambient temperature: dilute acids, most caustics, brines, and water-treatment polymers. XLPE (1.9 SG, cross-linked polyethylene) raises the engineering margin for aggressive chemistries (concentrated sulfuric, sodium hypochlorite, hydrogen peroxide) and adds resistance to environmental stress cracking. FRP vinyl ester (Derakane 411 / 441 series) takes the chemistries that polyolefins cannot hold — concentrated nitric, hot caustic above 150 degrees F, oleum, certain aromatic solvents. Polypropylene (PP) overlaps HDPE with slightly better heat tolerance (up to 180 degrees F continuous) and is the standard for fume-scrubber sumps. PVDF (Kynar) sits at the premium end for high-temperature dosing skids and fluorinated chemistries.

Single-wall versus double-wall. The decision driver is the chemistry hazard category and the local secondary-containment requirement. RCRA-regulated wastes, NFPA 400 corrosives above the maximum-allowable quantity per control area, and any tank sited in a sensitive environmental setting (well-head protection area, surface-water buffer, indoor production floor without a dike) call for an integral double-wall configuration such as the Snyder Captor line. Outdoor bulk farms with a properly sized concrete dike can run single-wall vertical tanks with no compliance issue.

Specific gravity selection. Tank wall thickness is engineered to a specific-gravity rating (1.0, 1.35, 1.5, 1.7, 1.9, 2.2 in the standard Snyder lineup; equivalents from Norwesco and Chem-Tainer). The rule is simple: the tank SG rating must equal or exceed the specific gravity of the stored chemistry. Specifying under-rated SG voids the manufacturer warranty and accelerates wall fatigue.

Vent and overflow planning. Industrial tanks tied to a metering-pump dispense circuit need vent capacity sized to the maximum dispense rate, plus an overflow line routed to a safe collection point. Flooded vents and undersized overflow lines are common contributors to outdoor-bulk-tank failures during high-flow truck unloading. The manufacturer publishes the vent-and-overflow capacity per tank model; the specifier should size the lines to the maximum unload-pump or dispense-pump flow.

Procurement cadence and pricing. Standard plastic industrial tanks ship from manufacturer warehouses in two to six weeks depending on size, color, and fitting layout. Captor double-wall and 8,000-gallon-plus configurations run six to twelve weeks. List prices on this site reflect the current OEM published pricing before LTL freight; freight to the destination ZIP is quoted separately. Volume discounts on multi-tank capital projects are coordinated through our quote desk.

7. Custom fabrication when stock will not fit

Specialty industrial tank geometries route through our specialty & metal fabrication network. Typical custom builds for the general industrial segment: dual-laminate FRP (PVDF or polypropylene liner with FRP structural) for fluorinated chemistry above 150 degrees F; jacketed polyethylene for temperature-controlled batch service; lined steel for high-temperature concentrated acid; integrated agitator-mount tanks for batch dissolvers; bespoke footprints to fit retrofit projects inside an existing building shell; and 304 / 316L stainless tanks for service combining elevated temperature and chemical-resistance requirements outside the polyolefin and FRP envelopes. Lead times run six to sixteen weeks. The quote desk runs the spec dialogue with the fabricator and stays involved through commissioning.
