Abstract

The device is esp. for use in low and medium pressure areas, esp. gas pipes. It consists of a sealing unit, introduced into the tube. The nuts is formed by a gas-impermeable fabric, held by an elastic ring, which supports itself on the interior wall. - The sealing area of the fabric (1) is enclosed gas-proof by a circumferential fluid medium-charged hollow profile (5). A support (2), acting as introduction and stabilizer device, passes through its centre. The fabric is curved similarly to a cut lemniscate, when under pressure. The support has two connections (8,11) to the profile, one of which is non-flexible and has a clamp section (6) for locking and positioning.
