PE100+ Association launches trenchless pressure pipe installation aid

World Pipelines,

The PE100+ Association has launched an online assistant that is designed to help civil engineers identify the most suitable trenchless methods for installing ‘PE100’ high density polyethylene (HDPE) pressure pipe – the ‘No-Dig’ technical guide.

PE100 is often the preferred pipe material in small and medium diameter pressure networks. It is also ideally suited for use with a range of trenchless technologies.

The association focuses on promoting consistent high level quality in the production and use of polyethylene for PE100 pipes. Moreover, it consists of HDPE producers from around the world.

PE100 is based on the long term strength of the material, known as minimum required strength (MRS) of at least 10 MPa, in accordance to ISO 9080.

The guide covers new installation and rehabilitation of existing water and gas pipelines using trenchless methods. It was developed by the PE100+ Association in collaboration with co-sponsors: the European Plastic Pipes and Fittings Association (TEPPFA); Exova; Radius Systems; and Downley Consultants.

While Exova is a Swedish pipe pressure testing institute, Radius Systems offers solutions for the entire pipe lifecycle, and Downley Consultants provides global business and engineering consulting services in trenchless technology and geosynthetics.

The tool guides users through a decision-making process, which is based on the hydraulic capacity and pressure requirements of the pipeline, along with the physical and geotechnical conditions of the project. It then calculates the diameter and standard dimensional ratio (SDR) of PE100 pipe. It also identifies feasible methods for pipe installation.

Users can access information to help them better understand the capabilities of the various installation methods. They can also find out practical aspects, such as cleaning and inspection, excavation and space requirements, end fittings and safety.
