Drill mud manifold is a necessary device to inject the drill mud into the well to control the well.
??ZJGH- 35S drilling mud manifold consists of the Z23Y- 35/ 100 & Z23Y- 35/ 50 mud valve, high pressure spherical union, high pressure core union, tee, high pressure hose, elbow, pressure gauge, and pup joint etc.
Surface valve- group adopts gooseneck tee with compact structure, little fluid resistance and large power effectuality. Adaptor spool adopts on rigid different size cross valve- group can be directly used single pipe on site.
The high pressure unions are made from high- strength alloy steels and heat treated, can be easily replaced. The professional machine is used for the manufacture of the union. The fine- polished sphere and core achived sealing.
The sealing surfaces of both the gate and seat of the Z23Y- 5000psi mud valve are built up using hard alloy overlays for erosion and corrosion resistance, which prolongs the mud valve’s service life, reduces the operating torques and makes the operation easy.
With the walls thickened as applicable and heat treated, the elbow, reducing pipe, tee and cross are made from high strength alloy steels and can fully meet the strength and corrosion requirements.
In order to ensure the product quality, the parts that require high precision are manufactured using special technology and all pressure- containing parts are hydrostatically tested prior to assembly.
Operating Instructions
1. Clean and grease both the sealing face and sealing groove of unions and clean the inside of the line pipe.
2. Check whether all connecting positions are fastened.
Maintenance
1. Inject grease into the mud gate valve at specified intervals.
2. Check whether all connecting positions and fixing bolts are loose at specified intervals.
3. If the leakage around the sealing position occurs, the seal shall be replaced i mm ediately.
4. Keep the outer surface of the manifold clean and do regular painting to prevent rust.
Note:
The Z23Y- 5000PSI metal seated mud gate valve is only used as a shutoff valve and cann’t be used as a choke valve, otherwise the sealing surface will be damaged. GROUND CONTROL ASSEMBLYDuring 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.
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 string, but 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, 70MPa and 105MPa with appropriate test pressure of 70MPa, 105MPa and 140MPa.
3. Swivel manifold
Used to joint the control head, rigid manifold and blowout pipeline, the manifold consists of special EUE seamless steel pipeline union and swivel elbow.
The working pressure includes 35MPa, 70MPa and 105MPa with appropriate test pressure of 70MPa, 105MPa and 140MPa.
The manifold should be regularly inspected and lubricated, sealing ring should be replaced an
