1. Equipped with quick-release joints, easy to connect, and can be connected with API long round buckle / short round buckle / partial trapezoidal buckle, wide application range.

2. Double-balanced pipe structure. When using the lower interface for cementing operation, the pressure at the upper and lower ends of the rubber plug is the same, which eliminates the effect of negative pressure suction on the blocking pin, and the blocking pin is easily opened.

3, dual indicator structure, accurately display the passage of the rubber plug, easy for the operator to judge.

  • Compact structure, reasonable design and structure are made of high strength alloy steel, high pressure.

  • The bottom of the double plug cement head has a union type of quick-latch Joint for easy and casing to connect.

  • Indicator is used to indicate the whereabouts through the cement head into the casing.

  • Cement head cap and the body connecting thread, as well as quick-latch joint pitch trapezoidal screw thread are large, easy quick installation.

  • Internal balance cement head:Body I.D. greater than cementing plug diameter, the internal pressure balance can be achieved.
