Civil construction solutions for HDD mud system - Construction & Construction Materials
KES Separation is a professional manufacturer of mud recycling system for trenchless/HDD drilling. Key equipment of KES Separation trenchless/HDD mud cleaning system includes shale shaker and desanding mud cleaner. After treatment, big size solids particles are separated, clean drilling mud will be pumped back for reuse. After many years’ experiences, we can offer standard mud cleaning system as below table, we can also customize HDD mud system according to customer requirement.
HDD is a state-of-the-art trenchless construction technology designed to install underground pipelines (e.g., oil, gas, water, and communication pipelines) without disrupting surface infrastructure like roads, rivers, or buildings. It features three core stages: directional pilot drilling, hole enlargement, and pipeline pullback. The technology relies on high-performance drilling slurry to cool the drill bit, lubricate the drill string, stabilize the borehole wall, and carry cuttings to the surface, making it ideal for complex urban or sensitive environmental areas.
Solids control equipment plays a critical role in HDD operations. It purifies the returned slurry by separating rock cuttings, sand, and other solid particles through a multi-stage process (shale shaker, desander, desilter, and centrifuge). Purified slurry can be recycled, significantly reducing slurry procurement costs and waste discharge. Moreover, stable slurry performance prevents borehole collapse and drill string wear, minimizes unplanned downtime, and ensures the smooth progress of pipeline pullback, which is key to improving HDD construction efficiency and project success rate.
Key Advantages:
- Can effectively control drill fluids performance, reduce the drill-jamming accidents and improve pore-forming quality;
- Can save bentonite and barite; drastically reduce the waste mud transportation cost;
- The effective separation of soil slag by equipment will help to improve pore-forming efficiency;
- The slurry closed cycle purification mode and lower slag moisture content reduce the impacts to environment;
- Safe and easy operation, simple maintenance, stable and reliable operation.
