The PE100+ Association has launched an online assistant for trenchless pressure pipe installation.
The ‘No-Dig Technical Guide’ is designed to assist civil engineers identify the most suitable trenchless methods for installing PE100 high density polyethylene (HDPE) pressure pipes.
It covers new installation and rehabilitation of existing water and gas pipelines using trenchless methods, and was developed by the PE100+ in collaboration with co-sponsors the European Plastic Pipes and Fittings Association (TEPPFA), independent Swedish pipe pressure testing institute Exova, UK-based Radius Systems, and Downley Consultants.
The online tool guides users through a decision-making process based on the hydraulic capacity and pressure requirements of the pipeline and the physical and geotechnical conditions of the project.
It then calculates the diameter and standard dimensional ratio (SDR) of the PE100 pipe necessary, and also identifies feasible methods for installation of the pipe.
The guide also comes equipped with in-depth information to help them better understand the capabilities of the various installation methods, as well as practical aspects such as cleaning and inspection, excavation and space requirements, end fittings, and safety.
Links are provided for each method which enables the user to contact suppliers of materials and equipment, and to find more information about the technologies and their applications.
PE100+ Association President Hans Pierik said “PE100 pipe is at the heart of water and gas distribution systems all around the world, so it is critical that designers and engineers make the right decisions when they develop projects for new trenchless pipe installations or rehabilitation of old pipelines.
“Our partners and PE100+ have spent a lot of time and effort ensuring that the No-Dig Technical Guide will enable them to make those decisions.
“This guide will help users decide whether or not trenchless techniques can be used to install PE100 on a specific project, which techniques are the most effective, and what key points need to be considered in using them.”
The association’s aim is to promote a consistent and high level quality in production and use of polyethylene for PE100 pipes, it is made up 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.
It is the preferred pipe material in small and medium diameter pressure networks in many countries and suited for use with a range of Trenchless Technology methods.
