API Hydraulic Lock Ram BOP.jpeg
"BOP body, side outlet, ram body, and other pressure-bearing sections made of defect-free forged metal, as well as its oval-shaped inner chamber, which reduces stress concentration and improves sealing performance.
To satisfy a variety of applications, the double ram BOP can be outfitted with several ram types, including pipe rams, blind rams, shear rams, and variable diameter rams.
It can be split into three types based on the number of rams: single ram, double ram, and triple ram."
