Product Description Product Description:Some additional details about the usage methods and characteristics of drill rods in the rock coring and drilling industry:Usage Methods:Wireline Coring: Drill rods are commonly used in wireline coring, a method that allows for efficient and rapid retrieval of core samples. The drill rods are connected to a wireline system, which enables the retrieval of the inner core barrel without removing the entire drill string. This method reduces downtime and allows for continuous coring operations.Soil Stabilization: Drill rods can be used for soil stabilization purposes. In some cases, grouting or injection techniques are employed where drill rods are inserted into the soil and grout or stabilizing materials are injected through the rods to improve the soil's strength or prevent erosion.Inclinometer Installation: Inclinometers are used to measure the deviation or angle of boreholes. Drill rods are utilized in installing inclinometers, where the rods with inclinometer casing are inserted into the borehole, allowing for accurate measurement of ground movement or deformation.Usage Characteristics:Rod Handling Systems: Drill rods are often used in conjunction with rod handling systems, such as rod handlers or automated rod racks, which improve safety and efficiency during the handling and storage of drill rods.Rod Protection and Maintenance: Drill rods require regular maintenance, including cleaning, inspection, and lubrication, to ensure optimal performance and longevity. They may be stored in protective cases or racks to prevent damage and corrosion.Rod Coupling Types: Drill rods can have various coupling types, such as male-female threads, friction-welded connections, or quick-release couplings. The choice of coupling depends on factors such as drilling method, equipment compatibility, and ease of assembly and disassembly.Thread Locking Systems: To prevent unintentional loosening of threaded connections during drilling operations, drill rods may incorporate thread locking systems, such as mechanical locknuts or thread-locking compounds.Rod Breakage Detection: In some cases, drill rods may be equipped with sensors or monitoring systems to detect any potential rod breakage or failure, ensuring the safety of the drilling operation and personnel.Rod Material Strength: Drill rods are designed to withstand high axial loads, torque, and bending moments encountered during drilling operations. The material strength and mechanical properties of the rods are carefully selected to ensure reliable performance in challenging drilling conditions.Rod Compatibility with Drilling Equipment: Drill rods are manufactured to be compatible with specific drilling equipment, such as drill rigs or coring machines, ensuring seamless integration and efficient operation.Rod Transport and Logistics: Considerations are made for the transport and logistics of drill rods, including their length, weight, and packaging, to facilitate easy transportation to drilling sites and minimize handling and storage costs.These additional details provide further insight into the diverse applications and important characteristics of drill rods in the rock coring and drilling industry, highlighting the specialized techniques, equipment, and considerations involved in their usage.Parameter tableSizeOuter Diameter (mm)Inner Diameter(mm)AQ44.737.3BQ55.746.1NQ70.060.2HQ89.078.0PQ(PHD)114.5101.5BTW56.348.0NTW73.364.0HTW91.381.0AW/AWJ/AWY43.730.7BW/BWJ/BWY54.038.0NW/NWY66.851.0HW89.071.042mm42.030.050mm50.037.060mm60.048.070mm73.054.690mm89.069.0S75A71.060.0S95A89.078.0S110110.098.0S130129.0117.0 Name:Wireline Drill RodProduct Basic parametersModel:AQ,BQ,LTK48,NQ,NQ3,HQ,HQ3,PQ,PQ3 NTW, BTW, HTWMaterial:Alloy Steel TubingDimensions:0.5,1m, 1.5m, 2m,2.5,3m length or customizedColor:Black or customizedApplications:Drilling ToolsStandard:ISO-9001Application:Mining or geological Drilling Rod ModelOD (mm)ID (mm)Thread Pitch(mm)Pin Length(mm)Rod Length(m)Unit Bundle Qty (pcs)BAU(Q)55.646.18.544.5319/25/30NAU(Q)69.960.38.544.45319/25/30HAU(Q)88.977.88.544.45319/25/30BRAU(RQ)55.646.18.542319/25/30NRAU(RQ)69.660.38.542319/25/30HRAU(RQ)88.977.88.542319/25/30PHD11410210.263379/25/30 FAQ:Q1: What safety precautions are required when using drilling rods?A: Proper PPE like steel toe boots, hard hats, gloves, and safety glasses should always be worn. A drilling rod safety zone should be established and only authorized personnel allowed near rig. Falling objects protection may be required overhead.Q2: How are threaded connections on drilling rods tested?A: Common tests for threaded connections include torque testing during makeup to specified values, tension/compression testing, galling tests, and pressure testing. Non-destructive methods like ultrasonic or X-ray are also used to inspect for defects.Q3: What is the common process for on-site drilling rod inspection?A: Visual inspection checking for corrosion, scratches, pits, dents, cracks. Connection inspection with feeler gauge to check threads for wear. Diameter measurement to check wall thinning. Magnetic particle testing may also be used periodically for more in-depth inspections.Q4: What is the purpose of drill pipe protectors/stabilizers?A: Heavy duty tapered rings placed at various points in drill string help centralize pipes and protect vulnerable connection areas from abrasion and damage from contact with borehole walls during drilling and tripping operations.Q5: How is downhole survey data collected?A: Downhole survey tools electronically measure drill string azimuth, inclination and depth at various points and log this data in memory modules. Known as MWD (measurement while drilling) when integrated into bottomhole assembly, or LWD (logging while drilling). Data downloaded post-trip.
