Product Description Product Description:In the drilling industry, a drill rod is a critical component used in various drilling applications. Here are some key details about drill rods:Purpose and Function: Drill rods serve as the backbone of a drilling system, transmitting rotational torque and axial force to the drilling bit or tool. They provide stability and support to the drilling assembly while allowing the drilling fluid to circulate and cool the drilling bit.Construction and Material: Drill rods are typically made of high-strength alloy steel to withstand the rigors of drilling operations. The steel used is often heat-treated to enhance its strength, hardness, and resistance to wear. The most common steel grades used for drill rods include S135, G105, and E75.Threaded Connections: Drill rods feature threaded connections at each end to facilitate the joining of multiple rods and the attachment of drilling tools. The most prevalent thread types used in the industry include API (American Petroleum Institute) threads, such as API Reg and API IF, as well as other proprietary thread designs specific to manufacturers or drilling applications.Length and Diameter: Drill rods come in various lengths and diameters to accommodate different drilling depths and borehole sizes. Common drill rod lengths range from 1 to 6 meters (3 to 20 feet), while diameters typically vary from 42 to 114 millimeters (1.6 to 4.5 inches).Drill Rod Joints: Drill rods are connected using threaded joints that ensure a secure and leak-free connection. These joints consist of a male (pin) and female (box) thread that are tightened together using a wrench or other specialized tools. The joints must be properly tightened to prevent thread damage and maintain the integrity of the drill string.Drill Rod Protection: To enhance the longevity and performance of drill rods, various protective measures are employed. Thread protectors are used to safeguard the threaded connections from damage during transportation and storage. Additionally, wear pads or hard-facing coatings may be applied to critical areas of the drill rods to minimize wear and extend their service life.Inspection and Maintenance: Regular inspection and maintenance of drill rods are essential to ensure their safety and reliability. Visual inspections, dimensional measurements, and non-destructive testing techniques, such as magnetic particle inspection or ultrasonic testing, are employed to detect any defects, cracks, or signs of wear that could compromise the integrity of the drill rods.Drill Rod Handling: Proper handling of drill rods is crucial to prevent injuries and maintain their condition. Specialized equipment, such as rod handlers, rod racks, and lifting devices, are used to safely lift, transport, and store drill rods. Care must be taken during handling to avoid bending, kinking, or damaging the rods.Drill Rod Recycling: In an effort to minimize waste and environmental impact, drill rods can be recycled at the end of their service life. Recycling involves melting down the steel rods and reusing the recovered metal for other applications. This helps conserve natural resources and reduce the need for new steel production.Continuous Improvement: The drilling industry is constantly striving for improvements in drill rod design and performance. Ongoing research and development efforts focus on optimizing drill rod materials, connections, and manufacturing processes to enhance strength, durability, and overall drilling efficiency.Drill rods are a vital component in drilling operations, providing the necessary strength, stability, and support for efficient and effective drilling. Through proper maintenance and handling, drill rods can have a long service life, contributing to successful drilling projects in various industries, including mining, oil and gas exploration, geotechnical investigations, and environmental site assessments.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 is a drilling rod?A: A drilling rod is a heavy duty pipe that is thread on both ends and used to transmit rotational power and fluid down the drill string during drilling operations.Q2: What are drilling rods made of?A: Drilling rods are typically made of heavy walled steel pipe that is heat treated for strength. Alloys such as chromium, vanadium and molybdenum are often added to improve wear and corrosion resistance.Q3: What diameter and lengths are typical drilling rods?A: Common diameters for drilling rods range from 1.5 inches to 4 inches. Lengths typically range from 6 to 30 feet long depending on the drilling application and equipment.Q4: How much does a drilling rod weigh?A: The weight of a drilling rod depends on its diameter and length, but as a rough estimate a 6-foot long 2.5-inch diameter rod typically weighs around 100 lbs.Q5: What is the purpose of drilling rods?A: Drilling rods transmit rotational torque from the top drive or kelly to the drill bit at the bottom of the drill string. They also provide a conduit to circulate drilling fluid to flush cuttings from the bit and hole. BEST "wireline drill roid" galleryBEST company partnershipPacking and Shipping:TeamworkExhibition:
