This process involves heating the ends of the pipework which is being joined, until it is then forced together whilst heated forming a strong bond. This can include materials such as; polypropylene, polyethylene, PVDF and ECTFE pipe.

This process is most commonly used in plastic pipe work to join 2 lengths of pipe together or to join a length of pipe to a fitting. This is especially useful if you need a longer pipe than what is sold.
