[{"type":"text","content":"\n \nRNS Number : 0937Z Haydale Graphene Industries PLC 15 May 2019 \n\n \n\n\n\n\nFor immediate release\n\n\n15 May 2019\n\n\n\n\n \nHaydale Graphene Industries plc \n \n('Haydale' or the 'Group')\n \nNational Grid benefit analysis shows high level of confidence in Haydale's composite transition piece \n \nHaydale (AIM: HAYD), the global advanced materials group, has been working with National Grid to calculate the benefit case of its Composite Transition Piece (CTP), using a method developed by National Grid and verified by PwC during a previous audit. \nThis approach provides a risk rating for the benefits. In this case the risk was assessed by National Grid as 'low', meaning that National Grid can have a high level of confidence in the results it will achieve.\nThere are around 300 locations on the National Transmission System where gas pipes pass through reinforced concrete walls, for example into valve pits. Currently, several types of seal are used to prevent contamination by water or soil, but when these seals fail technicians face a major task to fix the problem. \nNational Grid has found that Haydale's CTP represents a huge step forward in safety and efficiency, solving a major problem for the national gas transmission network at a reduced cost over the systems life-time. The solution allows easy access to transition pipes at pit wall transitions for inspection and maintenance. Working in conjunction with National Grid, the innovative CTP seal units can be used to plug the gap between the pipe and the wall. It means that technicians can easily remove the unit and check the pipe for corrosion or damage. The CTP can then be replaced quickly in one simple operation.\nFinancially, the benefits of installing a CTP are significant especially when viewed over the entire design life of the unit. Taking less time to inspect the pit wall area with a CTP fitted means that just under £230k could be saved over a design life of 50 years per unit installed. This is comparing an inspection using the traditional methods with the composite solution. \nIn addition to the cost benefits, National Grid estimates that 700 fewer hours of 'at risk' activities will be needed for each CTP during its design life. Working on the pit wall requires technicians to work inside a pit which may be several meters deep. Bene...
