This webinar describes the work undertaken to numerically model the hydrogen diffusion in in-service fillet welds across a wide variety of pipe attributes, welding conditions, and thermal conditions. The document includes recommendations for post-welding nondestructive examination (NDE) delay times that correspond to time-to-peak-hydrogen (TTPH) and time-to-critical-hydrogen (TTCH) at four common locations around a fillet weld where hydrogen induced cracking is likely to occur.
PR592-242009-W01 GHG Reduction at Compressor Station Using Optimization with Physics-informed Models
This webinar describes a spreadsheet-based tool developed to meet this need. The tool evaluates station operating conditions and recommends station setpoints that minimize greenhouse gas emissions while meeting throughput requirements and respecting equipment...
