Gas Transmission Networks
When construction records are incomplete, the in-situ sampling of pipe or fitting materials to establish material type and composition is needed to allow safe and reliable connections to be made to the pipeline network.
A quick reliable, accurate and cost effective method to determine in-situ pipe or fitting material chemical compositions is required. When combined with hardness tests and/or other analysis the material composition values will allow the component material grade to
The objective is to determine if current portable Optical Emission Spectrometry (OES) or X-ray Fluorescence (XRF) equipment will meet National Grid requirements for material sampling and reduce operational costs.
The information provided by OES/XRF, if found to be accurate during this study, will supplement existing records and will achieve a reduction in the time required to sample materials.
Enhance current knowledge of the practicality and accuracy of material identification using current OES /XRF technology while under site conditions.
