| FIREGUARD® or UL2085: Double-wall fire-protected aboveground storage tank features an inner and outer steel tank with a unique lightweight thermal insulation material that exceeds the UL 2-hour fire test. Insulating material is 75% lighter than concrete, reducing shipping, installation and relocation costs. |  |
| FLAMESHIELD® aboveground storage tanks are manufactured with a tight-wrap double-wall design. Standard features include 2-hour fire-tested performance, built-in secondary containment and interstitial monitoring capability. |  |
| UL142: These requirements cover steel primary, secondary and diked type atmospheric storage tanks intended for non-corrosive, stable flammable and combustible liquids that have a specific gravity not exceeding 1.0 in aboveground applications (special construction available for s.g. >1.0) . Each tank type may be fabricated in a combination of various shapes (cylindrical or rectangular) and orientations (horizontal, vertical) with or without multiple compartments or on supports, as covered in this Standard. |  |
| F921® aboveground storage tanks are manufactured with a double-wall steel design. Standard features include built-in, testable, interstitial monitoring capability and impermeable secondary containment. The F921® delivers uncompromising performance, reliability, service and economy. |  |
| GEN-TANK Generator Base Tank provides sturdy support for your backup or emergency power generator. The low profile of the GEN-TANK design serves as the structural support for the generator and enclosure mounting, while providing storage for a complete supply of generator diesel fuel. |  |
| The F911® is an aboveground steel storage tank system manufactured with built-in secondary containment. The tank is supported inside an open-top dike, which has a solid steel floor and vertical steel walls. The dike allows for secondary containment, monitoring, overfill containment and recovery of product. |  |
| Sti-P3 ® single and double-wall underground storage tank features a pre-engineered corrosion protection system that provides ongoing monitoring of corrosion protection. The sti-P3 ®, system has provided reliable, long-term performance for over a quarter million steel underground storage tanks. |  |
| ASME Pressure Vessels: The ASME product line provides stamped pressure vessels, jackets, and coils. This product line is designed and built in accordance with the ASME Boiler and Pressure Vessel Code. Our factory is ASME certified. Both the U-Stamp and R-Stamp are available for all your new or existing Repair or Retrofitted equipment projects. |  |
| The AquaSweep Gravity Oil Water Separator is UL-2215 listed and STI engineered and labeled. Available in a range of capacities, flow rates, and effluent discharge efficiency levels rated as low as 5 ppm. Tanks can be designed from 300 to 50,000 gallons and handle flow rates from 45 to 10,000 gallon per minute. Single or Double wall designs are available. We use a variety of different coalescer materials to meet both your needs and UL-2215 requirements. Level sensors and safeguards controls are optional. All tanks are corrosion protected tanks built to nationally recognized STI standards with strict third party quality control inspection programs. |  |
| API 650: This tank is for vertical, cylindrical above ground closed and open top welded oil storage tanks of various sizes and capacities for internal pressures approximately atmospheric (internal pressures not exceeding 2.5 PSIG are available). This standard only applies to tanks that have the entire bottom uniformly supported and to non refrigerated service with a maximum operating temp of 200° F. | |
| API 12F: This tank is for shop fabricated vertical, cylindrical above ground closed top welded steel storage tanks. These are made in various sizes and capacities for internal pressures approximately atmospheric. |  |
| API 620: This tank is for welded, low-pressure carbon steel above ground storage tanks (including flat-bottom tanks) that have a single vertical axis of revolution. The tanks described in this standard are designed for metal temperatures not greater than 250 °F and with pressures in their gas or vapor spaces not more than 15 lbf/in2 gauge. | |
| AWWA: These tanks are for cylindrical welded carbon steel tanks for the storage of water at atmospheric pressure. These tanks are available in various sizes and capacities. Potable water tanks shall be designed with a roof; non-potable water tanks can be built with no roof. Approved internal linings are available for both tanks. |  |
