BLADDER TANK

AKTEK PRE-PIPED Bladder Tank Foam Unit

AKTEK Bladder Tanks are one component in a balance pressure foam proportioning system. It requires no external power other than water pressure to ensure correct operation. Both vertical and horizontal bladder tanks are designed and constructed in accordance with the latest revisions to ASME/DIN code. Proportioning is the introduction of foam concentrate into a flowing water stream to produce a foam solution. AKTEK offers a variety of proportioning equipment that will accurately accomplish this task with various types of systems such as Bladder tanks, balance pressure proportioning systems and inline balance proportioning systems.

Vertical and Horizontal Bladder Tanks

( AKTEK line of NFPA11 APPROVED BV TURKEY ) vertical and horizontal bladder tank systems are available from 50 gallons to 3,500 gallons in the vertical and 100 gallons to 6,000 gallons in the horizontal style. These systems provide a dependable and cost-effective foam fire protection for a variety of flammable/combustible hazard areas and because water is the primary operating medium, they are easy to operate and maintain. Bladder tanks are frequently used in small aircraft hangers, warehouses, helicopter decks, and storage facilities. When the tank is in operation, water is applied to the outside surface of the bladder and subsequently displaces the foam concentrate, which is contained inside the bladder, which then makes its way to the proportioning device and then is injected into the water stream. Bladder is manufactured in extremely durable material which has a ASTM bursting pressure in excess of 56 bar and constructed to conform to the inside dimensions of the tank. Tanks are supplied with brass trimmed valves with Teflon seats. All valves are labelled showing normal working conditions
All tanks are oversized to allow for any thermal expansion of the foam concentrate All tanks are certified and supplied with a label identifying the type of foam concentrate the system is designed for and the percentage ratio and tank size . All tanks include the following trim valve packages: tank shell drain/fill valve; tank shell vent valve, bladder vent valve and bladder drain/fill valve. The vertical and horizontal bladder tanks are designed and constructed in accordance with the latest revisions to ASME code, Section VIII for unfired pressure vessels with a working pressure of 12,5 bar and tested to one and one half times this pressure.

Specifications

The tank shell is constructed of steel, complying with ASME specifications, possessing a tensile strength of not less than 20,000 psi. The ircumferential, as well as the longitudinal body seam, are machine welded. The tank interior is sand blasted white and all welds and edges are ground smooth. The tank shell water inlet is screened to prevent bladder blow out or the entrapment of debris between the tank shell and the bladder. All other openings greater than 1" are also screened to prevent bladder blow out. The vertical tank assembly is supported by a continuous skirt with access holes for the bladder drain/fill valve and the tank shell drain/fill valve. Four feet are provided for anchoring the tank. The horizontal assembly is supported on two saddles welded to the tank and fitted with anchoring holes. Bladder is manufactured of nylon reinforced Buna-N. The bladder material shall have a ASTM burst pressure in excess of 56 bar and is constructed to conform to the inside dimensions of the tank. The diameter of the vertical tank skirt is equal to the shell diameter to give greater stability. Tanks are supplied with brass trim valves with Teflon seats and permanently mounted to the tank. All valves are labelled showing normal working position. Lifting lugs are permanently welded to the tank with eyes of approximately 1½" diameter. Both the vertical and horizontal tanks contain a perforated PVC center tube that permits greater agent discharge. All tanks are approximately 10% oversized to allow for any thermal expansion of the foam concentrate. All tanks are supplied with a label which identifies the type of foam concentrate the system is designed for, the percentage ratio and the tank size. Tanks are painted red enamel.

Options

Coal tar epoxy for coating the interior shell of the tank (for use in salt water environment).
