Hello again Shad, the 2 hole is generally a part of the pipe trade and refers to pipe flanges. That would lead me to believe that this individual is referring to something other than a plate test in the vertical and overhead position. Or else this is an ad for some form of pressure vessel or tank work where they generally weld a lot of plate to build the tanks and provide the first flange out on connection piping, usually considered a boilermaker. Just a thought. You might want to email them and see about getting more of the specifics. Regards, Allan
