  • HDPE pipe fusion or Heat Fusion Welding involves the heating of two HDPE pipe surfaces to a temperature sufficient enough to change the resin’s molecular structure to an amorphous (or pliable) state. The HDPE pipe is Butt fused together using a "fusion welder". The pipe pieces are held together via a clamping and the pipe ends are "faced" with a machining tool to establish clean, parallel mating surfaces, perpendicular to the centerline of each pipe. When fusion pressure is applied at the designated temperature and prescribed force, the molecules from each pipe surface end mix. As the joint cools, the molecules return to their crystalline state creating one homogeneous pipe. The result is a leak-free fusion joint that is as strong or stronger than the pipe itself. Sovereign Fusion Inc. offers a complete turnkey package. We not only supply the skilled manpower and fusion equipment, but can also possess the necessary equipment to place the finished pipes and assemblies.
