Objectives The Project seeks to prove that the currently conceptual approach to the problem is able, through trialling, to demonstrate that offers a viable, cost effective and less customer disruptive alternative to repairing/replacing gas risers. The Project can be considered a success if, upon completion of work: The product has demonstrated capability of performing the desired taskFeedback from the GDN engineers involved in the final stages of the project do not prohibit the further roll-out of the solution into normal working practice.
Abstract There are a large number of 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 and time consuming. NGGD alone as an example has an estimated 165,000 medium rise (3-5 stories) and 2500 high rise systems (above 5 stories). Gas risers can be located internally within the building or can run up an external face where they are anchored to the wall using metal brackets. The metal-on-metal contact between the pipework and the wall anchor encourages localised corrosion which can lead to leakage and structural issues for the riser. The issue also extends to situations where a riser system can pass through a wall or balcony. Often in these situations the pipework has been sleeved for protection, however, the metal on metal contact again can encourage localised corrosion. The GDNs would like to be in a position where a localised repair to this area of pipe can be undertaken which would stop leakage, halt further corrosion and provide support to the riser pipework. The Method would consist of a split sleeve which would be applied to the corroded area of pipework. The sleeve would be secured in place and injected with an industry approved repair resin through designated injection points on the body of the sleeve. The system will also be able to be cut with a standard mitre block to allow for use on angled areas of pipework.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above
