RESEARCH OF FIRE RESISTANCE OF PENETRATION RATES OF METAL PIPELINES

This article is devoted to research on the fire resistance of metal pipelines (penetration rates) under pressure from circulating water or steam operated in energy installations. The need for research is due to the lack of a method for testing the fire resistance of intersections of building structures with standardized fire resistance limits. The article presents both the methodology elaborated for testing metal penetration rates for fire resistance and full-scale tests of these penetration rates (dimensions 630 × 45 mm and 65 × 8 mm) in a wall of aerated concrete blocks with a thicknesses of 1200 and 800 mm.
