Block aluminium pontoons with polyurethane foam filler

The BPA pontoon is designed to reduce evaporation losses of oil, gas condensate and petroleum products with high saturated vapour pressure in vertical steel tanks with a pontoon, to prevent atmospheric contamination by hydrocarbons and to comply with the rules of petroleum products storage stipulated by GOST 15150. BPA is referred to repairable products of specific purpose according to GOST 27.003. The pontoon design is repairable. Reliability of the pontoon in conditions and modes of operation is characterised by the service life of the pontoon (not less than 20 years) from the moment of manufacture, with an overhaul period of 10 years; Monolithic blocks of the pontoon filled with rigid self-extinguishing polyurethane foam with closed microcells and in general the carpet of the pontoon is unsinkable, even in case of depressurisation of the aluminium box of the block; The pontoon in terms of ergonomics complies with GOST 12.2049. The carpet of the pontoon lies and completely covers the product surface, thus excluding the explosion and fire hazard between the surface of the pontoon and the product surface.
