BOP Stack

A BOP stack can well function in different environments of low or high temperatures or rich in sulphur. The blowout preventer assembly can meet diverse well control demands in processes of drilling, well testing and underground drilling. Our BOP stack ranges from 2 9/16" to 30" in its nominal diameter and from 3.5MPa (500psi) to 140MPa (20000psi) in the working pressure. The stack adopts a forged or cast body and can be closed manually or hydraulically.
