What's the fire suppression ring for the drain pipe? What are the requirements?
The fire ring is made from metal shell material, filled with flame retardant expansion core material, sets the outer wall of the hard PVC pipe, and fixed on the floor or wall parts, fire core material heated rapidly, extrusion UPVC pipeline, in a relatively short time internal block pipe through the hole, stop the fire spread along the potential.
1, the application of the vertical pipe through the floor through the site.2 、 cross the partition of the fire zone and the two sides of the firewall.3, cross tube wells pipeline or pipe hole retaining wall through lateral parts.And in section 5.1.17, the fire ring shall be installed in accordance with the requirements of the product. The installation shall be close to the floor or wall of the floor, and shall be fixed with expansion bolts.
According to China's Ministry of housing GB 50242-2002 "building water and heating engineering construction quality acceptance" in indoor drainage system installation section 5.2.4: ring of fire or fire resistance should be set according to the design requirements of casing plastic drainage pipe design of high-rise buildings.
When the drainage pipe PVC in high-rise buildings (plastic), to prevent fire when the plastic tube is burned out, the fire spread from the lower to the upper Di, therefore, the plastic drainage pipe must be installed when wearing floor fire circle, its role in the affected by the high temperature expansion in the fire circle the pipeline "jam", reached the fire not up to stretch.
