Fireproof coupling FIREFORT CLUTCH M160 L100 KM-FF-C-160-100 KM LO34679 KM SYSTEM

The firestop sleeve is used in civil and industrial construction and is installed on all types of plastic drainage and internal sewage systems. The design of the FIREFORT CLUTCH KM-FF-S firestop sleeve consists of a metal body with a fastener and a special liner made of fire-resistant expanding material. In case of fire, plastic pipes burn down to the sleeve, the steel body heats up and transfers heat inside the sleeve. The liner made of thermo-reactive material expands and instantly seals the resulting opening, blocking oxygen access and the spread of fire to adjacent rooms. Fire resistance limit is 150 min. Installation of the firestop sleeve is simple and does not require special tools. Fixing the sleeve to the wall is done using fasteners. The product complies with the requirements of the current TU 123-FZ "Technical Regulation on Fire Safety Requirements" and GOST 53306 "Intersections of building structures with pipelines made of polymer materials."
