Product Description Product Description: Some more details about drill rods:Types of Drill Rods: There are different types of drill rods available, depending on the specific drilling application and requirements:Wireline Drill Rods: Wireline drill rods are commonly used in diamond core drilling. They feature a thin-walled design to allow for the retrieval of the core sample without removing the entire drill string from the borehole. Wireline drill rods typically have a flush joint connection that enables quick and easy assembly and disassembly.DTH (Down-The-Hole) Drill Rods: DTH drill rods are used in DTH drilling, which is a percussive drilling method commonly used in mining, quarrying, and construction. DTH drill rods have a thicker wall compared to wireline rods to withstand the high impact forces generated by the drilling hammer. They usually have a male-female threaded connection that provides a secure and robust joint.Hollow Drill Rods: Hollow drill rods are utilized in specific drilling techniques where fluid circulation is required, such as reverse circulation (RC) drilling. These rods have an inner tube that allows drilling mud or air to be pumped down the rod, cooling the drill bit and carrying cuttings or samples back to the surface.Auger Drill Rods: Auger drill rods are used in auger drilling, a method commonly employed for soil sampling, environmental investigations, and geotechnical studies. Auger rods consist of a solid shaft with a helical flighting that helps transport soil or other materials to the surface as the rod is rotated.Drill Rod Diameter and Wall Thickness: Drill rods come in various diameters and wall thicknesses to accommodate different drilling requirements. The selection of the appropriate diameter and wall thickness depends on factors such as the drilling method, the anticipated drilling forces, and the desired drilling depth. Thicker-walled drill rods are generally used for more demanding applications that involve higher drilling forces or deeper boreholes.Wear Protection: Drill rods are subjected to significant wear and abrasion during drilling operations, especially in challenging formations. To enhance their durability, some drill rods feature wear protection mechanisms. This can include hard-facing or carbide inserts on the rod's outer surface or specialized coatings that improve wear resistance. These wear protection measures help extend the lifespan of the drill rods and reduce the frequency of rod replacements.Drill Rod Handling Equipment: Handling drill rods can be physically demanding and potentially hazardous. To ensure safe and efficient handling, various equipment and tools are available:Rod Elevators: Rod elevators are used to lift and suspend drill rods during makeup or breakout operations. They provide a secure grip on the rods, allowing for safe and controlled handling.Rod Tongs: Rod tongs are wrench-like tools used to tighten or loosen threaded connections on drill rods. They provide a mechanical advantage, allowing operators to apply sufficient torque to make or break connections.Rod Spinners: Rod spinners are used to rotate drill rods during the assembly or disassembly process. They provide a powered rotation motion, making it easier to thread or unthread the connections.Rod Handlers: Rod handlers are specialized machines or devices used to automate the process of handling drill rods. They are commonly used in large-scale drilling operations where the frequency of rod changes is high.International Standards: The drilling industry follows various international standards to ensure the quality and compatibility of drill rods. The American Petroleum Institute (API) sets standards for drill pipe, including specifications for dimensions, thread types, material properties, and inspection requirements. Other organizations, such as the International Organization for Standardization (ISO), also provide standards related to drill rods and drilling equipment.Drill rods are essential components in a wide range of drilling applications, and their design and characteristics vary based on the specific drilling method, geological conditions, and operational requirements. By understanding the different types, features, and handling considerations of drill rods, drilling professionals can effectively select and utilize these tools to achieve successful drilling outcomes.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 are directional drilling tools for?A: Allowing precise borehole trajectory control through techniques like adjustable steering tools and wired drill pipe communication.Q2: What challenges occur in deviated/horizontal sections?A: Increased friction/vibration, stability issues, sharp turn management, enlargement risks, fluid volumes, accurate surveying, navigating targets require special techniques.Q3: What is the purpose of downhole hammers and bits?A: Hydraulic/pneumatic hammer action generates percussion forces to facilitate cutting through formations resistant to rotary drilling, providing faster penetration.Q4: What is the difference between drill bit types?A: Tri-cone bits have rotating cutter cones. Roller cone bits' cones don't rotate. PDC bits use bonded superhard diamond segments instead of steel teeth for harder formations.Q5: What safety equipment do operators use?A variety of PPE is required depending on hazards including fire resistant clothing, harnesses, gas detectors, hearing protection, respirators, emergency equipment and more.
