Single ram BOP

The shell of ram BOP is forged or cast, and the shell ram chamber is elliptical or rectangular on the longitudinal section of the vertical piston rod. The ram is operated by manual power assist mechanism or hand wheel. The shell is designed with an automatic sand cleaning structure, and the ram is designed with an automatic centering structure. The ram body has a special tooth structure, which can clamp the pipe string, bear the weight of the pipe string, and realize the slip and sealing functions.

Technical characteristics

The opening and closing of rams are controlled manually, without BOP control system.

Less parts, compact structure, small volume and light weight.

The shell and side door are made of low alloy steel forgings with strong pressure bearing capacity.

It can be equipped with a turbine rod labor saving mechanism to effectively reduce labor intensity.

Low manufacturing cost and simple maintenance.
