| Objectives | The objectives are: Assessment of the performance of the NuFlow product in relation to the requirements of the riser liner specification; due cogniscance given to (consistency of application, wall-thickness, adhesion, pressure loss, design life, etc. ). Observation of operational processes which will enable the development of operational guidelines for implementationAssessment of pressure loss; pre and post-liningObtainment of qualitative and quantitative data which will improve the quality of the new liner specificationIf the pressure loss assessment determines that there is a significant effect post-lining, development of a pressure loss simulation model will be undertaken (equivalent lengths per component) which will enable the effects of the lining to be simulated. Successful performance of liner technology in accordance with the specificationInvestigate limits of technologyPressure loss assessment and creation of pressure loss methodology (if required)Better understanding of operational processes which can be used to develop operational guidelines. | |
| Abstract | There are a number of Multiple Occupancy Buildings (MOBs) across the country with gas risers. These risers, usually constructed of steel or copper, are coming to the end of their expected operational life, and to replace these using existing construction methods will be expensive, disruptive and time consuming. Development of an alternative method to either remediate or replace these systems is required. The proposed solution will build on existing work completed to investigate the possibility of utilising a liner system that was developed in the water industry to line lead water pipes. It is believed this technology can be transferred to the UK Gas market to enable the remote lining of the internal pipe wall in multiple occupancy building risers. NGG and the other GDNs have previously progressed work in this area and projects were completed to test epoxy liner products in a test environment and more recently, a specification was developed to support this technology. The method would involve a small excavation being carried out at the base of the riser upright. Once the pipeline has been separated, a calculated measure of grit (dependant on length and diameter), is blown through the pipeline in order to clean the internal pipe wall. This would quickly be followed by warm air to ensure the epoxy liner securely bonds to the internal pipe wall. The epoxy liner would then be blown through the pipeline using forced air up through the riser into the customer’s property. Any overspray from the liner material would be collected in a pre-designed collection devices so not causing unnecessary mess to the customers property.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
