Abstract
The butt-welding of pipes made of crosslinked polyethylene, the most efficient joining method for the material PE-X, which up to now has been regarded an ‘non-weldable’, will enable it to be used for industrial and underground pipes and hence will make a major contribution to state-of-the-art and future-orientated pipeline applications.
In the future, it should also be possible to weld PE-X pipes with diameters of less than 90 mm and work is also being performed to develop welded joints with the same temperature resistance as the pipes. This will permit the use of welded PE-X pipes for hot-water systems and heating technology.
