PIPE JOINING | MACHINERY
Leak prevention UK-based Pinweld is pressing ahead with its patented joining technology – winning a number of development grants. The technology uses a vibrating pin to ‘stitch’ plastics articles – including pipe sections – together. The company has a long-standing relationship with TWI in the UK, which has tested and validated the process for polyethylene sheet and will later move on to plastic pipes. In addition, Bath University is currently testing the technique for sheet up to 10mm thick, and 6mm-thick pipe. Pinweld says that its technique could replace – or augment – established pipe joining processes such as electrofusion and butt fusion. It says that leakage from water pipes is typically caused by an approximate 25% failure rate for electrofusion jointing. One grant, from Innovate UK, will help it to develop the AI system that underpins the system. It also has grants confirmed from the UK water-servic- es regulation authority, Ofwat. Pinweld is also looking for potential industrial partners that are interested in the technique – both
inside and outside the UK, and in areas other than drinking water (such as irrigation and sewage pipe).
