Product Description Product Description Product Name: Premium Drill Collar for Precision Oil & Gas DrillingApplication: Oil and Gas DrillingP530,P550,P650 A. Slick Drill CollarNote: Drill collar is mainly used to provide bit weight to drill bit so that drill pipe is in tension. Especially drill collar can keep drill bit centralized and hole track by large rigidity. B. Spiral Drill CollarNote: Spiral drill collar is used to reduce contact area with hole so as to avoid efficiently bit sticking from diffirential pressure. C. Spiral Drill Collar With Elevator Groove And Slip GrooveNote: Elevator groove and slip groove made on box thread face of slick drill collar or spiral drill collar can be used as lifting sub and safety slip when trip out. Hardbanding is optional at customers' requests.D. Non-magnetic Drill CollarThe as cold rooled finish on both ID and OD surface with unique technical process strengthen the structure and ensures the tools with optimal resistance to stress,corrosion,cracking and the mechanical performance is greatly enganced.Key Features:Premium Material - Made of high-strength alloy steel, heat-treated, and inspected via ultrasonic testing for enhanced fatigue resistance and durability.Wear & Corrosion Resistant - Special surface treatment improves abrasion and corrosion resistance, extending service life.Stable Drilling Performance - Optimized design minimizes vibration, enhances verticality, and reduces drilling risks.Usage Instructions:Installed below the drill pipe to provide weight, stabilize the drill string, and improve drilling accuracy.Inspect threads before use to ensure secure connections and prevent downhole failures.Regular maintenance and non-destructive testing (NDT) are recommended to ensure safe operation.When ordering please specify:Drill Collarmodel;Connection, if non-standard;size and weight.Product Parameters Number AndConnection TableProduct CodeODIDLength mmBevel Diameter mmBending Strength Ratio mm inmm in NC23-31Z01/Z02-0100079.43 1/831.81 1/4915076.22.57:1NC26-35(2 3/8 IF)Z01/Z02-0200088.93 1/238.11 1/2915084.52.42:1NC31-41(2 7/8 IF)Z01/Z02-04000104.84 1/850.829150101.62.43:1NC35-47Z01/Z02-06000120.64 3/450.829150114.72.58:1NC38-50(3 1/2 IF)Z01/Z02-07000127557.22 1/491501212.38:1NC44-60Z01/Z02-23000152.4657.22 1/49150 or 9450144.52.49:1NC44-60Z01/Z02-23100152.4671.42 13/169150 or 9450144.52.84:1NC44-62Z01/Z02-08000158.86 1/457.22 1/49150 or 9450149.22.91:1NC46-62(4 IF)Z01/Z02-08100158.86 1/471.42 13/169150 or 94501502.63:1NC46-65(4 IF)Z01/Z02-09000165.16 1/257.22 1/49150 or 9450154.82.76:1NC46-65(4 IF)Z01/Z02-09100165.16 1/271.42 13/169150 or 9450154.83.05:1NC46-67(4 IF)Z01/Z02-11000171.46 3/457.22 1/49150 or 9450159.53.18:1NC50-67(4 1/2 IF)Z01/Z02-11100171.46 3/471.42 13/169150 or 9450159.52.37:1NC50-70(4 1/2 IF)Z01/Z02-12000177.8757.22 1/49150 or 9450164.72.54:1NC50-70(4 1/2 IF)Z01/Z02-12100177.8771.42 13/169150 or 9450164.72.73:1NC50-72(4 1/2 IF)z01/z02-24000184.27 1/471.42 13/169150 or 9450169.53.12:1NC56-77Z01/Z02-13000196.87 3/471.42 13/169150 or 9450185.32.70:1NC56-80Z01/Z02-14000203.2871.42 13/169150 or 9450190.13.02:16 5/8 REGZ01/Z02-15000209.68 1/471.42 13/169150 or 9450195.72.93:1NC61-90Z01/Z02-16000228.6971.42 13/169150 or 9450212.73.17:17 5/8 REGZ01/Z02-17000241.39 1/276.239150 or 9450223.82.81:1NC70-97Z01/Z02-25000247.69 3/476.239150 or 9450232.62.57:1NC70-100Z01/Z02-180002541076.239150 or 9450237.32.81:18 5/8 REGZ01/Z02-19000279.41176.239150 or 9450266.72.84:1
