This lightweight, removeable composite General Transition Piece (GTP) is used for sealing around pipelines where they pass through concrete walls, such as inspection pits, across a multitude of utilities including gas, water and oil and gas. This allows for time and cost-effective inspection and repair at pipe transitions.
The company has also has received an expression of interest for a further 60 over the next six years.
Paul Ogden, a senior civil engineer with National Grid, said: “During the next six years, up to 60 of these units are likely to be installed in the national transmission system and will significantly improve safety as well as creating savings of up to £5 million in the next five to 10 years, with further savings beyond that.”
Haydale’s GTP lightweight system has been jointly developed with National Grid via their innovation initiative. The GTP provides effective sealing around the pipe for up to 50 years, and allows pipe transitions to be inspected by a two-man crew, without the need for excavation, demolition, or lifting equipment.
The system was given an ‘Award of Merit’ at National Grid’s 2016 Chairman’s Award, held in New York, USA.
Keith Broadbent, managing director composites at Haydale, commented: “The removable composite GTP system is a huge step forward in safety and efficiency, solving a major problem faced by utility providers. Haydale is pleased to have found a solution and is working alongside National Grid to see the first fully installed and in use in the UK. With such a novel, advantageous innovation, it is not surprising to see our GTP system move from research and development to commercialisation so quickly. We look forward to working with more utilities companies, globally.”
