Ground Control Assembly--High-Pressure Union/Plug Valve

During the cause of test ,fluid should be controllably guided into separator and burner after flowing through drilling rod or tubing, the assembly is named as control assembly, which can control the pressure and flow-rate of the fluid safely and effectively.
Quantity:
  • FOTMA

Ground control assembly
Brief introduction:
During the cause of test ,fluid should be controllably guided into separator and burner after flowing through drilling rod or tubingthe assembly is named as control assembly, which can control the pressure and flow-rate of the fluid safely and effectively.

1. Control Head
Jointed with the upper of the test string, control head is classified into rotary head and un-rotary head of two kinds, and also into three kinds of 35MPa.70MPa and 105MPa according to the bearing pressure,and it can let the high-pressure fluid flow out of stringbut also pump fluid into well.
 
2. Rigid manifold
Used to control fluid pressure and flow-rate,rigid manifold is jointed with control head upwards and connected with separator and blowout pipeline downwards.
The working pressure includes 35MPa,70Ma and 105MPa with appropriate test pressure of 70MPa,105Ma and 140MPa .
 

 
Movable and check

3. Active manifold
Used to joint the control head, rigid manifold and blowout pipeline, the manifold consists of special EUE seamless steel pipeline union and active elbow .The working pressure includes 35MPa,70Ma and 105MPa with appropriate test pressure of 70MPa105Ma and 140MPa.
The manifold should be regularly inspected and lubricatedsealing ring should be replaced and sealing tested to ensure safety in test .

Ground Control--Plug Valve
Brief introduction:
Plug valve is a key part that is connected with high-pressure manifold in operation of cementing well and fracture in oil field and also suitable to high-pressure fluid control.
 
PLUG valve

Notice: Under the 10000PSI pressure, the valve can be easily opened or closed .
 
Plug Valve

Operation & Application:
Plug valve shall be clean and high- -pressure grease shall be injected into valve chamber in time,otherwise there may be leakage on the outlet.
Before usage, it should be inspected whether the opening/ closing situation be in line with sign and hand wheel turning at 90 degree can create open/ close.
 
Plug Valve.

Maintenance
Constant maintenance can prolong the working life of valve;
The clean and injection of oil/grease should be executed after work is over.
Regularly check whether all seals is damaged, the damaged seal should be replaced immediately;
As the seal of the piston and liner fail, it should be disassembled and inspected, it can be polished or replaced.
