| Objectives | The objective of this project is to achieve a G23 approved, final design of a standard PE Syphon fitting for use on new PE network which meets the following criteria: Compatible with standard electrofusion jointing methodsAvailability in various diameter bands (to be determined)To be accessed via syphon stand pipe at road/footpath surface for liquid removalAbility to be retro fitted to metallic distribution systems in cases of chronic water ingress investigation and rectification The project will be deemed successful if: A prototype/import of a PE syphon fitting that meets all criteria set out in the Objectives has been designed/identified, tested, trialed and gained G23 approval | |
| Abstract | Each year GDNs experience a significant number of events of water ingress into low pressure gas distribution pipes. When water enters a gas network, a risk to consumers arises from water forming seals in undulating pipes; this often results in reports of poor pressure and interruptions to gas supply. Ingress into the network can occur through leaking pipe joints, fractures and due to "third party" damage caused by the failure of the water network. In many cases, the location at which water naturally collects can be some distance from the point of water ingress. Historically, syphon points were installed at known low points in the metallic low pressure gas network to allow the collection and subsequent removal of water, MEG and other liquids from the gas distribution system. IGEM/TD/3 states that where necessary, provision should be made for the removal of condensate and other liquids from the system, by the installation of syphons, dip pipes or dip pipe collars located at low points. There are currently no specific designs available in the UK to construct a PE pipeline syphon and there are no UK PE fitting manufacturers who currently produce such a fitting. A global technology search for syphon designs that may be used in fully welded polyethylene gas distribution networksRequirements gathering, concept design and prototyping of a polyethylene syphon constructed from GIS/PL2 approved pipe and electrofusion fittings. Laboratory testing and field trial (under G23) of prototype/import PE Syphon at multiple locations on the NGN network. Discussion with polyethylene pipe and fitting providers regarding the supply of PE Syphons and approval as a permanent attachment to the network.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
