Recent changes in Federal regulations governing high-pressure gas transmission pipelines require that pipeline operators have traceable, verifiable, and complete documentation of the pipe material comprising their pipelines. In cases where documentation of pipeline material does not meet the regulations, this physical testing must be completed on material removed from the pipeline. EWI’s material test laboratory...

As interest in transitioning to hydrogen as a replacement for fossil fuels increases, there is a need to evaluate existing natural gas pipelines to see if they can be effectively retrofitted for safe, reliable hydrogen transport. EWI has established a joint industry program to conduct rigorous testing, close the knowledge gaps, and develop operator guidance...

Compromised “kissing bonds” in solid-state welds are tough to identify with conventional ultrasonic testing. Recently, EWI investigated using the ultrasonic process known as full matrix capture/total focusing method (FMC/TFM) to detect kissing bonds in intentionally fabricated kissing bonds, and found that these weak welds could be positively identified. This promising research is discussed in Detection...
