The primary tank and FRP jacket are separated by an interstitial space with the jacket acting as the secondary containment and corrosion barrier.” Secondary jacket allows for interstitial monitoring capabilities. Glasteel II tanks may also be built with or without multiple compartments for multiple fuel storage. Glasteel II tanks are built to Underwriters Laboratories specification standard UL-58 and UL-1746 part III. Glasteel II tanks are atmospheric steel tanks intended for storage underground of flammable and combustible liquids. Threaded fittings can be located along the tank top centerline or they can be installed inside containment sumps.

300 to 50, 000 gallon capacity Material of construction may be carbon or stainless steel Underwriters Laboratories Construction, UL-142 Single or double wall steel configurations available Also available in rectangular constructions up to 24, 000 gallons Available with multiple compartments for multiple fuel storage Modern's Steel Storage Tanks are compatible with gasoline, diesel, fuel oil, ethanol, methanol and additives Lined internally for special applications, such as jet fuel or potable water storage Tanks may be supported on stationary saddles, anti-roll stabilizers or structural skid configurations Tanks available with pump platforms and accessories Fuel dispensing equipment available Horizontal Configurations These are steel atmospheric tanks intended for aboveground storage of non-corrosive, stable, flammable, and combustible liquids that have a specific gravity not exceeding that of water. Maximum allowable working pressure is 0.5 psig as measured from top of tank. Tanks can be furnished with stationary support saddles, anti roll supports or structural skids. Only new steel materials are used in tank constructions. Each tank is sized with the appropriate normal and emergency vent openings as defined in the tank's standard of construction. Horizontal tanks may be single or double wall construction. If the tank is a double wall configuration, then it has interstitial monitoring capabilities. Tanks may also be built with or without multiple compartments for multiple fuel storage. Tanks are built to Underwriters Laboratories specification standard UL-142.

Modern Welding Company subsidiaries are ASME Code, 'U' stamp approved. This certifies Modern Welding Company to fabricate Section VIII Division 1 pressure vessels. In addition to these, Modern Welding Company has "R" stamp certification to perform repairs and alterations to boilers and pressure vessels as issued the National Board of Boiler and Pressure Vessel Inspectors. Technical Service Modern's staff has in-house ASME code verification software, Compress by Codeware, which gives you the best fabricated pressure vessel for your investment. Drawings are developed using AUTOCAD by Autodesk, computer aided drafting, for accuracy and clarity. Welding Procedures and Material of Constructions Modern has a library of up to date, certified, welding procedures developed for welding many different kinds of ferrous and nonferrous metals. These procedures consist of SMAW, GMAW, GMAW-S, FCAW-G, FCAW-S, SAW & GTAW welding processes. Testing and Examinations All nondestructive examination is supervised by our in house Level III technician and AWS Certified Welding Inspector. Examinations Include: Visual Examination Magnetic Particle Examination Radiographic Examination Penetrant Examination Ultrasonic examination Leak Testing Additional destructive testing is performed by Quality Control personnel. Training Modern's in-depth welder training program is conducted by an AWS Certified Welding Educator. This assures skilled craftsmen who are educated and familiar with the latest welding technologies. Training is also extended to our Quality Control Inspectors with certification performed in accordance with ASNT, American Society for Nondestructive Testing.

500 to 50, 000 gallon capacity Material of construction may be carbon or stainless steel Underwriters Laboratories Construction, UL-142 Single or double wall steel configurations available Available with multiple compartments for multiple fuel storage Compatible with gasoline, diesel, fuel oil, ethanol, methanol and additives Lined internally for special applications, such as jet fuel or potable water storage Tank supports may be, flat bottom, beam legs or skirt Tanks available with pump platforms and accessories Special pumping equipment available Vertical Configurations These are steel atmospheric tanks intended for aboveground storage of non-corrosive, stable, flammable, and combustible liquids that have a specific gravity not exceeding that of water. Maximum allowable working pressure is 0.5 psig as measured from top of tank. Vertical tanks may be of single or double wall construction. If the tank is a double wall configuration, then it has interstitial monitoring capabilities. These tanks may also be built with or without multiple compartments for multiple fuel storage. Tanks generally have flat bottoms and conical roofs. Special fabrication can incorporate dished tops, dished and coned bottoms all supported on skirts or legs. Only new materials are used in tank construction. Each tank is sized with the appropriate normal and emergency vent openings as defined in the tank's standard of construction. Tanks are built to Underwriters Laboratories specification standard UL-142. For special applications, such as products that have a larger specific gravity than water, Modern offers American Petroleum Institute, API, designed tanks in the API-620 or API-650 design configurations.

300 to 50, 000 gallon capacity Underwriters Laboratories construction, UL-142 and or STI's nationally-recognized standards with strict third-party quality control inspection program Available in these configurations: SuperVault™ - 4 hour fire rated "Protected", Multi-Hazard Listing Fireguard™ - 2 hour fire rated "Protected" models Flameshield™ - "Fire Resistant" models Double wall models Single wall models Available with multiple compartments for multiple fuel storage Compatible with gasoline, diesel, fuel oil, ethanol, methanol and additives Lined internally for special applications, such as jet fuel or potable water storage Tanks may be supported on stationary saddles or skid configurations Tanks available with pump platforms and accessories Special pumping equipment available Material of construction may be carbon or stainless steel "IOC™" Integrated Overflow Compartment: Modern's IOC tank was created to eliminate spills, environmental cleanup and monetary loss related to overfilling aboveground storage tanks. Modern's special overfill prevention design directs the excess product into the "Integrated Overfill Compartment". This only happens when the product level in the tank exceeds the 95% capacity rating. Each tank is sized with the appropriate normal and emergency vent openings as defined in the tank's standard of construction.
