Product introduction

This product is a self sealing wellhead device commonly used in oilfield workover operations. With the self sealing rubber core as the core sealing component, the rubber core of corresponding materials and structures can be selected according to the specific operating conditions of the oil well, which can be used in single stage or dual stage, so as to realize the sealing of well fluid when tripping the string, so that the well fluid does not fall to the ground, thus ensuring operation safety and environmental protection. Main materials: alloy steel, carbon steel, rubber, etc.
