HDPE is polyethylene pipe used for underground infrastructure. In butt fusion welding the ends of two pipes are heated and pressed together, and they cool into one continuous joint.
Why this method is used
- The joint is continuous and leak-free when made correctly
- It works for all pipe diameters
- The finished line can be pressure-tested
Where it is applied
For new underground installations and for repairs of existing pipelines, for example after a CCTV inspection has located a damaged section.
Pressure testing
After welding, the joints are pressure-tested to confirm they hold. This is part of how GCT delivers leak-free work.
Diagnostics and welding from one company
GCT finds the problem with CCTV and GPS and then welds the replacement section, so there is one team responsible for the whole job.
