Ritmo Pipe butt Fusion Machines are suitable for welding under-pressure pipes for water, gas and other fluids. The wide range of machines can weld pipes from 32 mm to 1600 mm dia. with ease and outstanding welding result.
HDPE pipe is butt fused by applying heat to prepared pipe ends and then pushing the pipe ends together with a pre-determined force to make a permanent butt fusion joint. It is a very simple process utilizing a properly sized butt fusion machine for the pipe size to be joined. The pipe ends are machined to mechanical stops to ensure clean, parallel pipe ends for the heating process. The pipe ends are then aligned using the clamps on the fusion machine. A heating plate in the machine heats the pipe ends according to the butt fusion standard. Once the heating criteria is met, the heater is removed and the pipe ends are brought together at the pre-determined force. This force is held on the joint for the time required by the standard. At this point, the pipe can be removed from the machine and visually inspected before pulling down the pipeline.
