Double-Containment Tanks for Hazardous Materials
Roben, Mfg, Inc. is a leading manufacturer of double-containment tanks for hazardous materials, offering advanced safety solutions engineered to prevent leaks, spills, and environmental contamination in high-risk applications.
Our double-containment systems are designed with a primary and secondary barrier, ensuring total control over hazardous substances in chemical, pharmaceutical, industrial, and waste treatment operations.
What is a Double-Containment Tank for Hazardous Materials?
A double-containment tank for hazardous materials is a specially engineered storage vessel that features both an inner (primary) tank and an outer (secondary) containment shell. The outer tank serves as a failsafe in the event of a leak or failure in the primary tank, offering additional protection against chemical exposure, environmental pollution, and operational hazards. These tanks are critical in applications involving flammable, corrosive, reactive, or toxic materials where containment integrity is essential.
Types of Double-Containment Tanks for Hazardous Materials
- Above-Ground Double-Walled Steel Tanks: Common for fuel, acids, and solvents, with robust steel construction for strength and fire resistance.
- Fiberglass Reinforced Plastic (FRP) Double-Wall Tanks: Lightweight, corrosion-resistant tanks ideal for harsh chemical storage.
- Polyethylene Double-Walled Tanks: Used for acids, caustics, and industrial chemicals with excellent chemical resistance and affordability.
- Underground Double-Containment Tanks: Engineered for safe below-ground hazardous material storage with leak detection systems.
- Vertical Cylindrical Containment Tanks: Space-efficient upright tanks with integrated secondary containment basins.
- Horizontal Double-Wall Tanks: Custom layouts for transport or facility integration with gravity discharge capabilities.
- Transportable Containment Tanks: Skid-mounted mobile tanks for temporary storage and emergency response.

Double-Containment Tanks for Hazardous Materials Frequently Asked Questions (FAQs)
1. Why are double-containment tanks necessary for hazardous materials?
Double-containment tanks provide a secondary barrier that prevents the release of hazardous materials into the environment if the primary tank fails. This added protection is critical for health, safety, and environmental compliance.
2. What materials are used in constructing double-containment tanks?
Common materials include carbon steel, stainless steel, FRP, HDPE, and thermoplastics such as polypropylene or PVDF. Material choice depends on the chemical properties of the stored substance and the application environment.
3. How is leakage detected in double-containment systems?
Leak detection systems such as hydrostatic sensors, electronic probes, or vacuum monitoring devices are used between the tank walls to provide real-time alerts in the event of a breach.
4. Are these tanks customizable to meet regulatory codes?
Yes, all Roben, Mfg, Inc. double-containment tanks are built to meet or exceed applicable regulations including UL, EPA, OSHA, and NFPA standards. Custom features such as alarms, venting, and insulation are available based on your needs.
