A method for enabling a lining (14) to be applied to a pipe elbow or bend C comprises the steps of connecting a tie member (12) to an end of a flexible elongate mandrel (1), 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 gvien orientation and deriving a profile S of the elbow or bend whilst 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.

Apparatus (1) for enabling a coating to be applied to an internal surface of a pipe elbow or bend C comprises aflexible body (2) adapted for location to extend within the pipe elbow or bend, and a bendable core (3) extending through the body.Bending of the core causes the flexible body to be bent in a similar manner. A method for applying the coating to the internal surfaceof the pipe elbow or bend (C) comprises the steps of shaping the flexible body (2) and locating it to extend within the pipe elbowor bend, and introducing a coating material so as to flow around and into a space defined between the flexible body and the internalsurface of the elbow or bend.

Pump wet end replacement method and impeller fixing mechanism
An impeller fixing mechanism is provided in a centrifugal pump for immobilizing the impeller, relative to the pump shaft and drive shaft of the pump, while effecting repairs to the pump, thereby eliminating much of the labor-intensive need for realigning the pump shaft and drive shaft and assuring accurate positioning of the impeller relative to the pump shaft. A method for effecting repairs of centrifugal pumps employs use of the impeller fixing mechanism of the invention to immobilize the impeller relative to the pump shaft, thereby facilitating the repair.

PUMP WET END REPLACEMENT PROCEDURE COMPLETE WITH AN IMPELLER FIXING MECHANISM
The pump comprises: one base, wet end and a rotating impeller connected to the drive shaft. The wet end has a casing formed by two bolted halves with faces or surfaces, inside the casing is the impeller screwed to the drive shaft. Wet end liner and impeller replacement is normally carried out by changing the complete pump or by dismantling the pump wet end in situ and removing the wet end liners and impeller component by component. To avoid vibration and prevent damage to the pump a precise re- alignment of the impeller and the drive shaft is necessary. Such a procedure during wet end liner and impeller replacement takes in excess of 8 hours. This long period of time is the technical problem that is resolved by the present invention which incorporates an impeller fixing device that allows removal of the pump wet end without disengaging the drive shaft from the coupling; therefore it does not require shaft re- alignment or wet end dismantling in situ. The impeller fixing mechanism is comprised of two elements concentric with the pump drive shaft, abutted against the casing faces. The elements are split-annular shaped, with a flexible elastomeric member and a stiff backing ring member where the clamping bolts fasten the mounting faces together. In addition, the backing ring member incorporates the mechanism for loosening the mounting bolts and nuts.
A liner assembly for use in a grinding mill, the liner assembly including a liner body including a mounting member, and an elastomeric cushioning member operatively connected to the mounting member. The cushioning member includes a plurality of support cavities therein, and a plurality of wear elements mounted within the support cavities.
