16 3/4 Inch 3000 Psi Drilling Spool Adapter Flange Wellhead
Drilling Spool Adapter Flange In oil drilling, a casing head is a simple metal flange welded or screwed onto the top of the conductor pipe (also known as drive-pipe) or the casing and forms part of the wellhead system for the well.
The Drilling Spool Adapter Flange , when installed, is typically tested to very strict pressure and leak-off parameters to insure viability under blowout conditions before any surface equipment is installed.
