Abstract
A device in a pipe coupling between a pipe end portion and a wall surrounding the pipe end coupling which is constituted by a socket, consists of a stop face device which is fixable in axial directions in relation to the surrounding wall and engages an end surface of the pipe end portion so as to define the final, fully seated position of the pipe end portion in relation to a surrounding wall of the socket when the pipe end portion is introduced therein. The stop face device becomes inactivatable subsequently to defining the position of the pipe end portion in the surrounding wall. The stop face device consists of one of four inactivatable structures including: the stop face device comprising a breakable material that breaks under the influence of an axially directed force exerted by the pipe end portion when the pipe moves during use, a stop face device comprising a flexible material that folds away under the influence of an axially directed force exerted by the pipe end portion when the pipe moves during use, a stop face device comprising a degradable material that degrades by the influence of medium flowing through the pipe, or by the stop face device being demountable, subseque…
