11 Inch Oil Rig Blowout Preventer System Cameron / Shaffer Type
Oil Rig Blowout Preventer System Features:
1. The design and manufacture of the Oil Rig Blowout Preventer System comply requirements of API 16A and GB/T20174 completely. It is equipped with rams of various dimensions that can meet all kinds of demands.
2. Pressure-bearing parts are made of high-quality alloy steel, so it is good strength and impact toughness.
3. The side door sealing adopts combined seal rings, so its well-killing sealing assistance ability is strong.
4. Use ram of floating or integral type, the sealing is reliable and it is easy for renewal.
5. Both sides of the shell chamber type adopt orthodrome type, transit arc all around, and lower the stress peak of the shell pressure bearing.
(We can provide the BOP: bore size from 7 1/16” to 30”, pressure from 500psi to 20000psi, Not limited in the below list)
