Fire-retardant ring Fire ring factory direct supply low price

The fire ring is a shell made of metal material, filled with a flame-retardant expansion core material, which is placed on the outer wall of a hard polyvinyl chloride pipe and fixed on the floor or wall. When a fire occurs, the core material expands rapidly when heated, extruding the pipe, and in a short period of time Seal the pipe opening within a certain period of time to prevent the fire from spreading along the opening. Qizheng fire-retardant ring has the advantages of compact structure, beautiful appearance, organic combination of leakage prevention and fire protection measures, and convenient construction and installation for fire protection. It provides a strong support for the promotion and application of drainage pipes in industrial and civil buildings, especially high-rise buildings. Fire protection. This product is exposed or concealed and fixed on the floor or both sides of the wall. It has good fire-retardant effect, long fire-resistant time, excellent fire resistance, moisture resistance and oxidation resistance, compact structure, beautiful appearance and convenient installation.
With China's rapid economic development and the end of the construction boom and real estate boom, issues such as safe and environmentally friendly energy have become increasingly prominent. Plastic pipes are widely used in various public and civil buildings, but plastic pipes often become channels for the spread of fire. The holes formed when plastic pipes are burned by hot fire resemble a chimney, allowing flames and smoke to spread from one layer to the other along the pipe. Spread to another floor, or spread and spread from one room to another, causing fire damage to expand. Fire protection organizations around the world have come to the unanimous conclusion that plastic pipes are the main culprit in the spread and spread of fire lanes.

The setting position of the fire-retardant ring
According to the Ministry of Construction of the People's Republic of China/Building Drainage Rigid Polychloride "Technical Regulations for Ethylene Pipe Engineering", high-rise buildings and other types of buildings with fire protection requirements should set up fire-stop rings at the following locations
If the main pipe diameter of the exposed pipe is greater than or equal to the floor plate penetration, a fire-stop ring should be set up< br/> A fire-stop ring should be installed at the part of the wall where the cross-branch pipe of an exposed pipe is connected to a concealed pipe
The ventilation pipe of the drainage pipe passes through the roof or the roof used to evacuate people in case of fire, and is set at the bottom of the roof panel
