Narrative
During an inspection at the bristol ridge valve site, product was observed at the packing gland fitting located on the mainline block valve. Operations control was notified and pipeline shutdown procedures were initiated. Mainline block valves upstream and downstream of the release were closed. The release originated from a crack on the 1/2" packing gland fitting located on the block valve. The mainline was drained up and a new 1/2" ball valve and plug were installed. Results of the failure analysis indicate the failed component was a non-oem fitting and as such, the configuration of the fitting allowed the aftermarket adapter to be inserted too far into the packing fitting which resulted in overtightening. The overtightening caused a crack in the non-oem fitting. Installation of the 1/2" ball valve and plug eliminates the need for this adapter fitting.
