| Objectives | If successful, the introduction of a semi-mechanised welding process, coupled with improved NDE weld assessment has considerable potential as it offers an innovative solution increasing the efficiency of network modifications and new customer connections. A successful outcome to this research and development project will be the adoption of the welding and NDE techniques within National Grid’s specifications. This will allow National Grid to specify a unified welding and post weld NDE for the installation of thick wall ‘hot-tap’ tees in future projects requiring these techniques. | |
| Abstract | Current methods used by National Grid (NG) to weld thick wall minimum hot tap or stopping off connections to a pipeline can result in extended continuous welding times in excess of 24 hours. This is undesirable from the key aspects of human factors (extended working hours), environmental (increases in atmospheric pollutants) and safety (accidental damage to pipework). The specific programme methods are: Identify suitable welding system & consumables, obtain all materials, develop trial programme, appoint welding & non destructive examination (NDE) sub-contractors and produce a Welding Procedure Specification (WPS) & Magnetic Particle Assessment (MPA) technique sheets, method statements and risk assessments. Produce test welds, examine by NDE and carry out mechanical testing of test welds. Assess results of all testing, produce Welding Procedure Qualification or Record (WPQR) sheets and project report. Produce new or revised text for inclusion in NG’s specifications T/SP/P9 & T/SP/NDT/2.Note : Project Documents may be available via the ENA Smarter Networks Portal using the Website link above | |
