13 5/8"-5000psi Annular BOP, Casted, Shaffer Type
Our Annular BOP is widely used in surface and subsea drilling in H2S field services. The packing element is the spherical or tapered type with massive storage volume, low operation pressure, and excellent sealing function Bonnet is hemispherical-shaped, so there is no stress concentration on the bonnet whenever bearing the pressure. so the pressure is evenly distributed; convenient for disassembly and assembly.
(We can provide the BOP: bore size from 7 1/16” to 30”, pressure from 500psi to 20000psi, Not limiting in below list)
