Structural composition

Mainly including cement head cylinder, top cover, plug valve, balance pipe, indicator, union interface, quick fitting joint, and screw stop pin

Characteristics

1. Equipped with a quick fitting joint, it is easy to connect on site and can be connected to API long round buckle/short round buckle/trapezoidal buckle, with a wide range of applications.  

2. The double balanced pipe structure ensures that the pressure on both ends of the rubber plug is the same when using the lower interface for cementing operations, eliminating the impact of negative pressure suction on the retaining pin and making it easy to open the retaining pin.  

3. The dual indicator structure accurately displays the passage of the rubber plug, making it easy for operators to make judgments.  

4. The main body is made of thick walled seamless pipes, which are high-pressure resistant and have a long service life.  

5. The top cover and union nut adopt large pitch trapezoidal thread, which is convenient for disassembly and assembly.
