A Closer Look at HDPE
Featured Product from McElroy Manufacturing, Inc.
The world’s infrastructure is changing. In piping systems both above- and underground, system design, installation, and maintenance have become top priorities, alongside considerations for sustainability, cost effectiveness, and quality assurance.
Because of the ever-increasing need for oversight and improved safety, welded high-density polyethylene (HDPE) pipe has emerged as one of the fastest-growing pipe materials available worldwide.
Thermoplastic pipe welding – also known as butt fusion welding and poly pipe welding – is the process by which two plastic pipe ends are faced, heated, and forced together under pressure to form a welded joint that is stronger than the material surrounding it.
Poly pipe welding is a reliable, trusted, and standardized method for joining plastic pipe together. Many standards exist to ensure the welding is performed properly and consistently. In Australia, ISO high force standards outline the acceptable practices for heat welding for polyethylene pipe and fittings, including heat and cool times and pressures required for different sizes of HDPE pipe. Since its arrival on the market in the 1960s, welded HDPE has become one of the most trusted materials for installation. …
