WO 200121999 A UPAB: 20010620 NOVELTY - Seal comprises a base section, at least one movable sealing element and an element for holding the sealing element in its initial closed position. DETAILED DESCRIPTION - The seal (4) for pipe joints formed by one pipe (2) inserted into another (1) comprises a base section (13), at least one movable sealing element (10, 11) and an element (12) for holding the sealing element in its initial closed position. The hold on the sealing element is released through dissolution of the holding element. This allows the sealing element to rise until it contacts the surface of the pipe (1) displaced from its initial position. USE - For sealing pipe joints formed by one pipe inserted into another. ADVANTAGE - The seal of simple construction is cost-effectively produceable. It is capable of quickly and durably compensating large gap variations brought about by various circumstances such as, for example, ground displacements.
