With mines in four continents, AngloGold is one of the key mining companies in the world. When retrofitting the 8″/219 mm high-pressure water lines in the Fraser Alexander Mine, they went looking for a solution that allows Fraser Alexander to easily add and remove pipes to and from the system.
The Victaulic Style SC77HP high pressure shouldered coupling is especially designed for mine dump and waste solutions and with a pressure rating up to 50 bar/725PSI, it could easily handle the high operating pressure of the
water lines. Because the piping system continuously needs to be replaced to accommodate the location of the water cannons, AngloGold also needed a solution that allows for easy system assembly and dismantling. This is exactly what the Style SC77HP coupling provides. The coupling design allows Fraser Alexander to easily remove a piece of 9-meter long pipe from the middle of the line by taking the housing apart, rolling the gasket over one pipe end creating the space necessary to roll the free pipe away from the others and not having to pull the surrounding pipes in any direction.
Installing the Victaulic Style SC77HP shouldered coupling proved to be the ideal solution for this project. Not only can the coupling stand the high-pressure ratings, but it also allows for easy removal and addition of extra pipe spools.
