MSP/DRILEX TEL 0086-02165538126



MSP/DRILEX offers a complete range of underbalanced drilling equipments, not only offers rotating BOP, but also rotating control heads. The products primarily include BW series and BG series. They are designed to handle today’s most demanding underbalanced drilling requirements.

The rotating control head is a versatile,rotating stripper rubber which seals tightly around Kelly,drill pipe,drill collar, tubing or casing and other drill string components while diverting dust, mud, air/gas,or steam away from the rig floor. Mud, dust air/gas, or steam is diverted through the side outlet, thus keeping the wellhead and floor area safe. It can be used for drilling in areas susceptible to kicks or blowouts, drilling under pressure,drilling,underbalanced drilling.

The BG series rotating control head is a lower pressure product,while the BW is a higher pressure product. The working pressure of BG series is up to 500psi and the BW series is up to 5000psi. Both of them are rotary or top drive capable and offer unprecedented serviceability of its dual strippers rubbers that are stretch-fit and self-actuating for additional safety,as pressures increase while drilling.
