Specificaion
The tank shell is constructed of steel, complying with ASME specifications, possessing a tensile strength of not less than *0,**0 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 *6 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 *0% 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..
