A pipeline is only as strong as its weakest connection. When it comes to joining HDPE pipe, there are several common methods that are used, each with its advantages and disadvantages. In this article, we’ll discuss four different methods: butt welding, electrofusion, flanging and mechanical coupling – focusing predominantly on the ease and speed of installation, the need for specialised equipment and experienced personnel, and the strength and reliability of the joint.
On this page, you can find links to technical articles on pipeline engineering written specifically for contractors and engineering professionals. Topics include how to select or design pipelines, new pipe technologies and how they work, and factors that affect pipeline longevity.
The process of relining or renovating damaged or leaky concrete, GRP or ductile iron pipes with profiled polyethylene (PE) has been around for many years and has proven to be a reliable form of pipe rehabilitation in almost all fields of operation. The adoption of pipe relining technologies allows for the construction of new, self-contained pipe systems using the old pipe system as an empty conduit for the new PE pipe, thereby providing increased stability and a high static load capacity, especially when using profiled pipes in larger diameters.
