Abstract
A method for enabling a lining () to be applied to a pipe elbow or bend C comprises the steps of connecting a tie member () to an end of a flexible elongate mandrel (), drawing the tie member through the elbow or bend so as to draw the mandrel therethrough and locate opposing ends of the mandrel adjacent to opposing respective ends of the elbow or bend, and securing the mandrel ends in relation to the respective ends of the elbow or bend. The mandrel can be adapted to the elbow or bend by locating the elbow or bend in a given orientation and deriving a profile S of the elbow or bend while in that orientation, removing the elbow or bend and then locating the mandrel in the given orientation, and adjusting the mandrel in relation to the profile of the elbow or bend to adapt it thereto.
