FIELD: pipelines.
SUBSTANCE: group of inventions relates to fire couplings for a pipeline, such as a pipe, cable or device, passing inside a wall, ceiling or floor in a building. Intumescent fire clutch includes at least one layer (4) of intumescent material and one bearing layer (5) connected to layer (4) of intumescent material. Said fire clutch has length (L) which corresponds at least to circumference of pipeline for which it is intended. At least bearing layer (5) has elastic characteristics and, thus, bearing layer (5), in unstated position, has the ability to twist around itself in a spiral.
EFFECT: present invention also relates to a roll of such intumescent fire-fighting couplings and to a method for installation of such intumescent fire-fighting clutch.
