18 Inch Shaffer Annular Bop Annular Blowout Preventer For Drilling
476.3 Mm 18 3/4 Inch Annular Blowout Preventer For Drilling
The Annular Blowout Preventer BOP stack field proved its efficiency in performing good isolation around the drill pipe, across the open hole, and for performing shearing on the drill string. Here you will be able to understand Shaffer BOP ram and annular preventer type components and function.
(We can provide the BOP: bore size from 7 1/16” to 30”, pressure from 500psi to 20000psi, Not limiting in below list)
