PE Pressure
PE pressure pipe systems are manufactured using PE100 high density polyethylene material. Other lower class materials are available but are generally not used for pressure applications.
Polyethylene is a very versatile material that has exceptional corrosion and chemical resistance; high impact resistance; flexibility, weather resistance and can be installed in trenched and trenchless applications.
PE Pipes and fittings can be joined using an economical mechanical compression joint for smaller diameter pipes or by fusion welding a joint using either the butt-weld or electrofusion processes.
PE Pressure Pipe
PE pressure pipes can be manufactured in a wide range of pressure classes and sizes.
The benefits of PE100 material, make it an ideal product choice for many applications such as potable & non-potable water systems, mine water & slurry systems, gas pipe systems, compressed air systems, submarine pipe systems and industrial process pipework.
Pipes can be made in straight lengths (all sizes) or coils (small diameter pipes) with colour coded stripes for application identification.

PE Electrofusion Fittings
As an alternative to butt welding, the PE Electrofusion process provides a unique socket fusion welded system for PE pipes and fittings.
The PE EF fitting has socket ends with embedded heating elements, that require an electrical input from a welding machine to melt the surface between the fitting socket and pipe spigot to form a homogenous welded joint.
