  • Reinforcing arrangement at pipe penetration
    Publication number: 20030127859
    Abstract: A reinforcing arrangement for a pipe penetration in an element such as a wall or a loadbearing element, particularly in an environment subject to vibration, the wall having a penetration aperture therethrough. The pipe penetration includes a tubular device which extends at least partly through the penetration aperture and is provided with an external circular bead received in the penetration aperture and by which the tubular device is axially affixable in the penetration aperture. A retaining device fixes the bead in the penetration aperture and fixes the tubular device. A reinforcing sleeve or pipe installed in the tubular device in the region of the circular bead to provide internal reinforcement and stiffening of the tubular device. The reinforcing sleeve prevents vibration generated fatigue fracture of the tubular device in the region of the circular bead.
