Pipes are critical for the infrastructure of many industries, especially for those operating in the oil, gas, and water sectors. High-density polyethylene (HDPE) pipes are increasingly used around the world due to their low cost, high durability, and excellent chemical resistance. However, while HDPE pipes can be joined relatively easily through butt fusion welding, it is important to understand the technical specifications of the welding machine to ensure a successful, high-quality joint.
