All of this products components are the result of metalworking following strict procedures and knowledge. Different versions are available: DN50, DN80, DN100 and DN150. Flange inlet depending on the requested flow rate. The POK foam spillway systems for tank gaskets are used to protect storage tanks, with floating roof and vertical opening, containing flammable or combustible liquids. They consist of two integrated components: a generator for foam production, a spillway to guide the foam to the bottom of the tank wall, at the gaskets surface. Each foam generator operates by transferring a pressurized foam solution through a calibrated stainless steel opening. Air is drawn through gills in the generator and vigorously mixed; the foam thus produced passes through the spillway and is projected outward. The foam then falls on the tray and spreads over the tanks gasket. POK foam generators for tank gaskets are available in four sizes with nominal flow rates from 300 to 2400 lpm, in increments of 100 lpm. The foam generation of these devices depends on the quality of the foam concentrate as well as the operating conditions. With a good quality foam concentrate and a pressure of 7 bar at the inlet of the generator, the expansion rate is about 8. Tank gasket spillways systems are suitable for use with all low expansion foam agents and for all types of fire hazard applications including oil and refrigerated solvent. The shape of the spillway avoids foam projections that would be counter productive in case of solvent fires. To ensure maximum protection of the tank gasket, the foam will form a circular ring around the floating roof. Thus, it is recommended to design a circular barrier of an anti-corrosion material. The foam is thus guided into this passageway with a sufficient depth. For optimum security, we recommend a pathway with a minimum volume of 0.3m x 0.3m and a maximum volume of 0.6m x 0.6m. This will provide perfect foam draining around the floating roof. The drainage grooves will allow rainwater to flow away, favouring foam production. In case of fire, a rapid response is required. To accomplish this, a detection system will instantly trigger the foam spillway system, thus avoiding sizeable damage.
