Rotary BOP:
It is commonly used in underbalanced pressure drilling to close the annular space between the drill and the wellbore, allowing the drill to rotate under rated dynamic sealing conditions to achieve pressure.
The shell material is used to produce low-alloy steel castings or forgings, and the chemical composition and mechanical properties as well as the forming process are in compliance with the corresponding standards.
Connection method: There are three kinds of connection methods in the upper and lower parts: planting wire connection, flange connection and clamp connection. Its connection flanges, bolts, clamps, and ring groove dimensions are all based on API6A and API16A standards.
