7 1/16″ Single Ram Bop Blowout Preventer For Oil Drilling Rigs
Single Ram Bop Features:
1. Single Ram Bop Body and side door are made of alloy steel;
2. Use seal rings assembly to improve the sealing of the side door;
3. Use floating-type ram. Front ram rubber is separated from top ram rubber, making it more reliable in sealing and easier to change;
4. Use buried oil way inside the body. The loading hinge is separated from the hydraulic hinge;
5. Compact hinge structure makes it easy to assemble and disassemble;
6. Use an arc-shaped body chamber with four round corners as a transition section to reduce stress peak value whenever bearing the pressure;
7. Ram cavity can be fitted with ram assembly of the same type BOP made abroad;
(We can provide the BOP: bore size from 7 1/16” to 30”, pressure from 500psi to 20000psi, Not limited in the below list)
