Function: 1. Drilling fluid circulation channel: As the linchpin for high-pressure mud transmission, it masterfully enables the seamless flow of drilling fluids.
2. Safety protection function: In tandem with IBOP, it provides swift closure of the flow channel, fortifying well control during emergencies.
3. Process optimization support: Its ingenious modular design ensures swift replacement, boasting a maintenance cycle of approximately 500 hours.

4. Dynamic sealing center: Employing a cutting-edge multi-stage sealing structure (O-ring + floppy disk), it effectively curtails drilling fluid leakage. The pioneering pre-tightening design offers real-time sealing pressure monitoring, enhancing emergency responsiveness.



After three groundbreaking generations of technological evolution;

First generation (Traditional Wash Pipe Assembly)
Constructed with a carbon steel matrix and carbide bushing, it relied on a multi-layer packing seal, demanding frequent grease replenishment every 50 hours.
Typical issue: Seal failures result in mud leakage, with an average lifespan limited to 200-300 hours.

Second generation (Adjustable Washpipe Assembly)
Incorporating Utex packing from the United States and domestic supersonic tungsten carbide flushing pipe, it dramatically extended lifespan in high-pressure, oil-based mud conditions.

Third generation (Mechanical Washpipe Assembly)
Innovations: The independent bushing structure was eliminated, requiring only the dynamic and static rings to be replaced during maintenance. This streamlined process reduces downtime for flushing pipe maintenance, minimizing operational impact.


 

 

 

Mechanical Washpipe Assembly;

Experience a revolution with our mechanical seal washpipe assembly, featuring an upper connecting nut, static ring, dynamic ring, dynamic ring anti-rotation pin, and lower connecting nut. Its unparalleled longevity, minimal maintenance, and steady performance mean you only need to change the dynamic and static rings each time. Under standard operations, extend the washpipe seal's life, achieving a continuous operation span of 1700 hours. With pressure capacities of 5000PSI and 7500PSI, it's perfect for NOV and various domestic Top Drive models. It shines in extreme environments with pressures up to 5000PSI and temperatures beyond 100°C. Maintenance-free throughout its service life, it eliminates daily shutdowns, slashing maintenance time and operational disruptions.

Daily maintenance:

1. Lubrication management: Ensure peak performance by adding grease to critical equipment nodes daily (2-4 flushes per location).
2. Leakage Check: Vigilantly monitor for mud leakage at the junction between the flushing pipe and the main shaft. Should leakage exceed a threshold of 5 drops per minute, it is imperative to halt operations immediately and replace the seal to ensure optimal functionality and safety.
3. Fastener Inspection: Conduct a daily assessment of the fixing bolts and anti-loosening gaskets of the flushing pipe. Ensure that the torque adheres strictly to established standards for unwavering operational reliability.
Monthly: Engage in a comprehensive disassembly and inspection of the flushing pipe assembly. Replace any worn packing, and attend to the O-ring by replacing it if its hardness has diminished by over 15%, safeguarding efficiency and longevity.
Seasonally: Undertake a thorough flushing of the hydraulic system to eliminate impurities within the sealing chamber, maintaining oil contamination levels at or below NAS-8, thus preserving system integrity and performance.




Key Technological Breakthroughs:

1. Sealing Revolution: Overhaul your system with a transition from traditional O-rings to cutting-edge hydraulic compensation seals and magnetic fluid seals, slashing leakage rates by an astounding 99%.
2. Material Upgrade: Experience remarkable durability with our tungsten carbide-based composite material, boasting a 200% enhancement in impact resistance. The advanced surface nano-coating dramatically curtails mud erosion.
3. Intelligent Integration: Elevate performance with seamless integration into the Top Drive control system, offering dynamic matching of torque and seal pressure, exemplified in models like the VARCO TDS-11SA.



Industry Application Value:

Efficiency Improvement: Our third-generation flushing pipe transforms operational efficiency, extending the replacement cycle from a mere 3 days to an impressive 30 days, markedly reducing downtime.
Safety Enhancement: Benefit from a real-time monitoring function that provides advance warnings of seal failures up to 48 hours before they occur, effectively mitigating risks of well control accidents.
Cost Optimization: Through strategic life extension initiatives, reduce the consumption of flushing pipes for a single well by a remarkable 60%, delivering significant cost savings.
