PROCEDURE FOR APPLYING A CORROSION PROTECTION ON A PRESSURE VESSEL AND PRESSURE VESSEL FOR FIRE EXTINGUISHING MEDIUM

摘要

The invention relates to a process for applying an anti-corrosive coat on a pressure vessel for fire extinguishing medium, wherein the vessel, preferably in a heating oven, is heated-up to a specified temperature, a duro-plastic material is applied uniformly on the internal wall of the prezheated vessel, and after a partial cooling down and, if necessary, after an intermediate storage, a duro-plastic material is applied on its outside at low temperatures, whereupon the vessel is assembled, filled and tested. The invention based pressure vessel, preferably a fire extinguisher, has the advantage, that due to a higher tensile strength of the internal and external coat a longer working life is achieved.
