Corrugated Bolted Steel Tanks are commonly installed on a concrete foundation. No steel floor is needed, as the concrete foundation becomes the floor of the tank. The tank walls are seismically anchored to the foundation as needed. Supports the Flexible Membrane NSF61 certified and Geotextile Pre-liner system.
Steel Floors are only used in the case that the tank is engineered to be self-anchored and installed on a compacted granular/road base ring foundation.
Anchoring of a tank is required when installing on a concrete foundation, in any location for any use. Unless the tank has a steel floor and is engineered self-anchored. Anchors meet ASCE7-10 and all AWWA requirements with the use of tall anchor saddles and A36 F1554 zinc or galvanized all thread anchor rods. Standard non-seismic anchors, Heavy Duty Seismic Anchors, Stiffener plates and Fully Stiffened options are all available.
Corrugated Bolted Steel Tanks have multiple roof style options to suit many requirements. Both structural and aesthetic. 30 degree V Rib, 10 Degree V Rib, Structured 30 degree V Rib, Structured 10 Degree J Rib, Flat Corrugated and 30 Degree Flat Panel Tanks are offered.
Partial Guardrails/ Full Guardrails/ OSHA Caged Exterior Ladder Systems, Anti Climb for Ladder Rungs and Cage, Deck Access Openings, Side Shell Manways, Catwalks, Roof Cap Walk Arounds, Frost Free Vents, Bridges and more are manufactured and used for safety as required on Corrugated Bolted Steel Tanks. See link to line drawings and photos.
FITTINGS AND APPURTENANCES:
ANSI 150# Flanges, Victaulic Groove Steel Flanges, Stainless Steel Threaded Flanges, OSHA caged exterior ladders, interior ladders, Site Gauges, Screened Vents, Frost Free Vents, immersion heaters, temp switches, etc. See link to drawings.
Interior polyiso insulation is installed inside the tank between the steel wall and a flexible membrane liner system. Elongated steel flanges are sized to fit the insulation. Immersion heaters can be installed as per NFPA22.
NSF-61 rated flexible membrane liner systems made from approved materials by AWWA D130 are available. Liners are welded to the dimensions of the tank prior to installation, and in some cases for very large tanks, some field welding required. Liners meet AWWAD 130 and Manual M25 written for flexible membrane liners and floating covers. Hypalon, Polypropylene and PVC are standard approved NSF61 liner materials. See link to drawings.
