In the process of oil production by pumping unit, high-pressure gas flow will appear suddenly in the well, If the wellhead is not equipped with a blowout preventer, the stuffing box alone is not enough to control the wellhead pressure and can easily cause a blowout. Therefore, it is necessary to install sucker rod blowout preventer at the wellhead.

The sucker rod blowout preventer developed and produced by our company with small size, occupies little space of wellhead, and is easy to operate. It is produced according to API 16A standard, and its sealing performance is safe and reliable.
