Heat Fusion/Butt Welding Services in Tasmania
AJ Water offers butt welding for HDPE piping using a fusion welder.
Two pipe pieces are held by a clamping device, and once clamped, the ends are ‘faced’ with a machining tool to establish a clean and parallel mating surface, perpendicular to the centreline of each pipe.
A heating plate is inserted between the faced ends, and the pipes are drawn together against it, which forms a melt pattern that penetrates into both pipe ends. Once the correct temperature is reached, the heating plate is quickly removed, and the heated ends are carefully moved together with a specific amount of force. This force must be continuous and held until the new joint cools and solidifies.
