| Objectives | The project objective is to develop a suitable alternative design of pipe support for use on the NTS. The project should identify options for alternative designs and materials for trial on a suitable NTS site. | |
| Abstract | The existing pipe supports on National Transmission System (NTS) sites are installed by different means and to different designs. Certain large diameter pipe supports cannot be removed without the breaking out of concrete plinths in order to inspect for corrosion between metallic surfaces underneath them. These steel pipe supports are also very heavy and present a manual handling issue to both remove and replace. Other pipe supports in use are welded to the pipe and as such the sliding mechanisms cannot be maintained without damaging the support and concrete plinth. This project looks to research potential alternative solutions to the above existing pipe support materials and design. First phase - study and produce options for different styles of pipe supports fabricated from composite materials. Second phase - design, development and any identified modifications of preferred option and field trials. Finite element analysis on a support of selected nominal diameter representative of the current split design in steel components. This will permit direct comparison with future design proposals incorporating alternative materials of construction. Phase three - Design proto-type, develop pipe support adopting the principles findings of the previous phases. Finite element analysis on 600mm and 900mm designs. Produce a manufacturing Specification. Presentations to National Grid technical stakeholders. Phase four - Trial composite supports in a working environment. Additional funding (£76k) Following a series of peer reviews at design meetings it was identified that finite element analysis are required for all remaining pipe sizes (300mm, 450mm, 750mm, 1050mm, 1220mm), and a G/19 (Procedure for application of model design appraisals) application and approval is required. Therefore Phase 4 has a revised list of deliverables, including the following:1. Finite Element Analysis (FEA) for all pipe diameters a. Production of drawings for remaining sizes: 300mm, 450mm, 750mm, 1050mm, 1220mmb. FEA on sizes 300mm, 450mm, 750mm, 1050mm, 1220mm2. G/19 (Procedure for application of model design appraisals) a. Production of G/19 application, including supporting documents b. Response to appraisal comments c. Completed and approved G/19 dossier 3. Prototype manufacture a. Finalise production methodology b. Produce three (3) prototypes for installation and evaluation (450mm, 600mm, 900mm)Phase five - Installation and evaluation of composite support design in a working environment (not currently costed)4. FEA testing5. During phase four it was identified that the installation and evaluation of composite support design in a working environment will not provide crucial point of failure evidence. Therefore phase 5 has been re-scoped to include: ?Review of Phase four destructive testing results and application in FEA Fabrication and testing of up to two rounds of destructive sample testing to validate FEA models Fabrication and load testing of up to two DN600 pipe supports, in accordance with Exova Method Document E-E-OP-EE-ME-DA-MD-M11: Static Strength Testing of Components & Structures Confirmation of G19 Design drawings and Performance specification, for review and adoption Provision of Project Close Out ReportNote : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
