The collar is made of a metallic shell, filled withfire-retardant expansion core material, set in the outer wall ofrigid PVC pipes, fixed in the floor or wall parts, the corematerial is heated to expand rapidly when the fire occurs,s UPVC pipes, sealing the pipe penetration in a relativelyshort period of time to prevent the spread of fire along the hole.This product enjoys a compact structure, beautiful shape, organiccombination of leakage prevention and fire prevention measures. Itis also convenient for construction and installation, whichprovides a strong fire protection guarantee for the promotion andapplication of UPVC drainage pipes in industrial and civilbuildings, especially in high-rise buildings.This product isinstalled openly or concealed and fixed in the floor part or bothsides of the wall, with good fire stopping effect, long fireresistance time, excellent fire resistance, moisture resistance,oxidation resistance, compact structure, beautiful shape, easyinstallation and other advantages.
