With the rapid development of China's economy and the construction of heat and real estate, the problems of safety, environmental protection and energy have become increasingly prominent. Plastic pipes are widely used in various public and civil buildings, but plastic pipes are often easy to become channels for fire propagation. The holes formed by plastic pipes in the event of heat burning are like a chimney, which causes flames and smoke to spread from one layer along the pipe. Spread to another floor, or spread and spread from one room to another, causing fire damage to expand. Fire organizations around the world have come to the conclusion that plastic pipes are the chief culprit in the spread and spread of fire. We all know the fire-stopping ring. Once a fire breaks out, the pipeline is often a lot of fire spread, and it is also a quick passage for Zui. The degree of rapidity is something we can't imagine, and the use of the fire-stopping ring solves this problem very well, which makes our life safety one more guarantee. This product is fixed to the floor or wall on both sides of the wall or the wall. It has good fire retarding effect, long fire resistance, excellent fire resistance, moisture resistance, oxidation resistance, compact structure, beautiful appearance and convenient installation.

The fire-stopping ring is made of metal material and filled with flame-retardant expanded core material. It is placed on the wall of the rigid PVC pipe and fixed on the floor or wall. When the fire occurs, the core material is rapidly expanded by heat, and the UPVC pipe is squeezed. Block the pipe through the hole in a short period of time to prevent the fire from spreading along the hole. This product has the advantages of compact structure, beautiful appearance, organic combination of anti-leakage and fire prevention measures, convenient construction and installation, etc. It is the promotion of UPVC drainage pipes and other types of hard plastic drainage pipes in industrial and civil buildings, especially high-rise buildings. The application provides a strong fire protection.
