Brief introduction of fire resistance ring

This product has the advantages of compact structure, beautiful appearance, organic combination of anti-leakage and fire prevention measures, and convenient construction and installation. It provides strong fire protection for the popularization and application of UPVC drainage pipes in industrial and civil buildings, especially high-rise buildings. This product is fixed on the floor or on both sides of the floor through exposed or concealed installation. It has good fire resistance effect and long fire resistance time. It has excellent fire resistance, moisture resistance, oxidation resistance, compact structure, beautiful appearance and convenient installation. With China's rapid economic development and the heat of construction and real estate, exposed safety, environmental protection, and energy issues have become increasingly prominent. Plastic pipes are widely used in all kinds of public and civil buildings, but plastic pipes are often easy to become the passage of fire. The holes formed by plastic pipes burned by heat and fire are like a chimney, so that flames and smoke spread from the first layer along the pipes. Spreading to another floor, or from one room to another, exacerbates fire damage. Fire organizations around the world have concluded that plastic pipes are the main culprit in the spread and spread of fire tunnels.

Place of fire stop ring

Installation of indoor drainage system according to GB 50242-2002 "Code for Acceptance of Construction Water Supply and Drainage and Heating Engineering Construction Quality" of the Ministry of Housing and Urban-Rural Development of China: Article 5.2.4: Plastic drainage pipes installed in high-rise buildings shall be equipped with fire-resistant rings or fire protection sleeves according to design requirements tube.
According to Article 4.1.3 of CJJ / T29-2010 "Technical Regulations for Plastic Drainage Engineering of Construction Drainage Pipes" (implemented on October 1, 2011) of the Ministry of Housing and Urban-Rural Development of China, the plastic drainage pipes laid in high-rise building indoors when the pipe diameter is 110mm or more , Should be set in the following positions:
