Introduction to HDPE Welding High-Density Polyethylene (HDPE) is a durable thermoplastic used in water, gas, and sewage pipelines due to its resistance to chemicals and corrosion. To securely join HDPE pipes, specialized equipment like HDPE welding machines are needed to form leak-proof, long-lasting connections. What is an HDPE Welding Machine? An HDPE welding machine joins HDPE pipes by heating the surfaces and pressing them together to form a solid bond. There are several types of HDPE welding machines, including: Key
