ACT-100® Steel/Fiberglass Reinforced Plastic(FRP) Storage Tank Specifications

Containment Solutions, Inc. is a licensee of the Steel Tank Institutes ACT-100® program.

The ACT-100® tank combines the structural integrity of a UL 58 listed steel inner tank with the corrosion resistance of a fiberglass composite coating and are available as single-wall and double-wall (Type I or Type II for unique applications) vessels. The exterior is clad with 100 mils, minimum fiberglass reinforced plastic which meets or exceeds all federal and state regulations. Laminate integrity is proved by a 35,000 volt spark test, which gives CSI the confidence to provide the Steel Tank Institutes limited 30-year warranty on any standard ACT-100® tank, for internal and external corrosion, and structural failure, while eliminating the need for cathodic protection and periodic corrosion monitoring.

Product Specifications:

Section 1: Application of FRP Laminate

1.0 Exterior FRP laminate shall be applied to a minimum dry film thickness of 100 mils and shall conform to all application and factory testing requirements of UL 1746, part II.

1.1 Threaded openings and flanged nozzles shall be protected during the blasting and laminating operations.

1.2 The entire exterior surface of the tank shall be commercial blasted in accordance with SSPC-SP-6. Not more than 12 hours shall elapse between completion of blasting and start of lamination operation.

1.3 Laminate shall be applied only when the work area and the tank steel are between 32° and 103°F.

1.4 The following materials shall be used:

    1.4.1 Isophthalic Resin, Reichhold 33-402 or equivalent.

    1.4.2 Methyl Ethyl Ketone Peroxide (catalyst) mixed with resin as recommended by resin manufacturer to gel in approximately 30 minutes and cure in approximately two hours.

    1.4.3 Glass fibers shall weigh 1.03 to 1.45 ounces per square foot of laminate and shall be sprayed up using 60 end 204 filament roving.

    1.4.4 In the final (flood) coat only, an ultraviolet (UV) inhibitor shall be added.

1.5 Base coat shall be resin and catalyst only, 5 to 8 mils dry thickness. After base coat has gelled, but prior to cure, intermediate coat of resin mixed with glass fibers shall be applied to a dry film thickness of 80-102 mils. Glass fibers must be thoroughly saturated with resin. Intermediate coat shall be rolled with segmented rollers to eliminate bubbles and voids. Final coat containing resin, catalyst, UV inhibitor, wax and pigment shall be applied after intermediate resin layer has gelled (but not cured) to a dry film thickness of 10- 15 rails. Total dry film thickness of all coats shall be 125 mils nominal, 100 mils minimum.

1.6 Quality control procedures:

    1.6.1 Visually check the base coat for complete coverage of the tank.

    1.6.2 Make a wet gauge check of intermediate layer to verify adequate thickness.

    1.6.3 Visual check of the flood coat to assure uniform color and that there are no cracks, crazing or evidence of voids or pinholes.

    1.6.4 After set-up and cure, a Barcol hardness test may be performed to verify hardness specified by resin manufacturer. This test will normally be performed as a random spot check.

    1.6.5 In the factory, prior to shipment, perform a 35,000 volt spark test over 100% of the surface of the tank. Repair and retest any holidays detected in accordance with UL requirements.

1.7 Upon receipt of properly completed Installation Check List, manufacturer shall furnish to buyer, in writing, a 30-year warranty. Warranty shall cover repair or replacement of tanks in the event of failure, through no fault of buyer, due to internal or external corrosion or structural failure for the term of the warranty at the original point of installation, provided that tanks are used solely for storage of petroleum products.

Section 1: Single-Wall Composite Tanks

1.0 Tanks shall be of diameter and capacity shown on the plans. Tanks shall be of welded steel construction, fabricated in accordance with Underwriters Laboratories Standard UL 58 and so labeled.

1.1 Tanks shall meet all applicable federal and state codes and regulations, and shall be compatible with the products to be stored.

1.2 Tanks shall be installed in accordance with NFPA-30 and all other applicable codes and regulations, and shall be furnished with complete manufacturer’s installation instructions and Installation Check List.

1.3 Tanks shall be ACT-100®, as manufactured by Containment Solutions, Inc. or approved equal able to meet all requirements herein.

1.4 Fittings and accessories:

    1.4.1 Each tank shall be furnished with fittings as shown on plans.

    1.4.2 Lifting lugs of adequate size and capacity shall be provided.

    1.4.3 Unless otherwise indicated on plans, each tank should be supplied (per customer requirements) with hold down straps and isolation pads with sizes and quantities per manufacturer’s recommendation.

1.5 Exterior FRP laminate shall be applied to a minimum dry film thickness of 100 mils and shall conform to all applications and factory testing requirements of ACT-100®.

1.6 Upon receipt of properly completed Installation Check List, manufacturer shall furnish to buyer, in writing, a 30-year warranty. Warranty shall cover repair or replacement of tanks in the event of failure, through no fault of buyer, due to internal or external corrosion or structural failure for the term of the warranty at the original point of installation, provided that tanks are used solely for storage of petroleum products.
