Overview
　　In oil and chemical projects of various sizes, various oil products, chemical raw material or chemicals are generally stored in the tank. For flammable liquid in the tank, in the event of fire, it is very destructive. Water is of no use for that fire in tank yard except for the most effective method, foam fire extinguishing system.
　　Foam fire extinguishing system, based on the fact that density of foam is less than that of the flammable liquid, covers the flammable liquid with foam to isolate air and put out a fire quickly. Coflexip foam fire extinguishing tube system, with much less foam consumption, can convey foam extinguishing agent to tank wall (slot wall) in faster speed than the conventional extinguishing system that sprays foam extinguishing agent at the tank roof edge.
　　Coflexip foam fire extinguishing tube system, through input pipe, tank, special "Coflexip foam fire extinguishing tube", with the help of "liquid mounted inner floating roof", conveys foam extinguishing agent from the bottom of floating disc to the "foam dispenser" at the top of floating disc before coming into the "T" shape sprayer at the tank wall through tube.
　　The design of Coflexip foam extinguishing tube system meets the standards of NFPA?1, API650 and China Standard GB50151-92's local amendment in 2000, suitable for tank with liquid mounted floating disc.
