No 6010 in the last 3 refineries I worked in.
Chevron - Pascagoula, MS
Conoco Phillips - Borger, TX
Shell - Anacortes, WA.
you need a better fit to use 6010, bad gaps and hi-lo are easier to cover up with TIG .I think they like it considering the sad state of affairs regarding the quality of the pipefitters you get nowadays.
