  • 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.
