Description

Piro Multitube PM intumescent tape is a polymer tape with an admixture of graphite and other components that make the assembly smooth and flexible, and under high temperature it increases its volume, closing the aperture with the pipe or cable on which it is wound. The cross-section tape has a rectangular shape and is manufactured in several sizes: 60 x 2.5 mm, 60 x 4 mm, 100 x 4.8 mm. The tape is rolled into a roll of various lengths, from 15 m to 30 m. In case of Piro Multitube PM intumescent tape, its unique feature is cross-section interchangeability. The strip cross-sections are interchangeable, which means that one cross-section can be replaced with another cross-section, the interchangeability of cross-sections is presented in the Pirosystem catalog. The fireproof intumescent tape should be cut off and adjusted to the outer circumference of the pipe, wrapped on the pipe and fixed with a cable tie or a self-adhesive universal tape.

Piro Multitube PM intumescent tape is designed for sealing and stopping fire in service penetrations of plastic and metal pipes without or with flammable or non-flammable insulation and cables penetrating walls or floors. Fire resistance class from EI 30 to EI 180. For more information see ETA-17/1061.

Piro Multitube PM does not require any support, therefore it can be mounted directly on the pipe at its destination. The tape is wrapped directly on the pipe or on the pipe insulation depending on the type of pipe and type of insulation (for details see ETA-17/1061). For pipes penetrating floor, wrapping with a tape can be done both before pouring the floor or part of the floor with concrete mortar, and when pouring the floor or part of the floor with concrete mortar. For pipes penetrating a wall, wrapping with a tape can be done while building the wall or part of it. For pipes led in a shaft or in technical openings, wrapping with a tape should be done before walling them up. In case of drilled holes, Piro Multitube PM should be wrapped and attached around the pipe and slided to the hole in the partition. Fixing the tape on the pipe can be done by using a cable tie or with a self-adhesive universal tape.
