Resident fluid should be guided to separator and burner after flowing to ground through drill pipeline in the test, and the assembly is named as ground control assembly, which can control the pressure and flow rate of the fluid safely and effectively.

Jionted with the top part of the test string, control head id classified into rotating head, and also into 35Mpa ,70Mpa and 105Mpa from its loading capacity,It can let high-pressure fluid flow out of string, and pump fluid into the well.

 It is used to control fluid pressure and flow manifold, with control head upwards and separator and relief pipeline downwards.

Rated working pressure of floor manifold: 35Mpa, 70 Mpa and 105Mpa .

It is used to connect high-pressure manifold of control head, floor pipe and relief pipeline, which consists special heavy seamless steel pipe union and movable elbow.

Rated working pressure of movable manifold is 35Mpa, 70Mpa or 105Mpa.

Movable manifold should be regularly inspected, lubricated, hydraulic sealing tested and its seal ring replaced for safety.
