Product Description Product DescriptionNon-magnetic drill collars have unusual design requirements, and as a result pose unique problems of corrosion resistance. Drill collars are the bottom components in a drill string, where their weight generates the force on the drill bit allowing it to drill and their stiffness allows the force to be transmitted without buckling. Conventional drill collars are made of alloy steel, like the rest of the drill string, and their corrosion usually poses no problems except to their threaded connections. A typical drill collar is 30 feet long and 4 to 9 inches in diameter.Features and Advantages1. Double Top Structure:drill pipr joints adopt the double ledge(double top)structure, such structure can enhance the tightness of joints so that the pressure of the mud could realize non-leakage half way. greatly reduce the resistance to polit drilling and back using this sturcture improves the torional strength of drill pipr so that the box thread will not deformed2. After optimal design of equal strength and the dispersion of stress to give dull play to the potiontioal of the drill pipr matrial.3. After forging joints materials, increased matrial density and change the material of fibrous tissue, thereby enhancing its machanical properties.4.Using joints nitride, phonsphide or copper treatment to ensure thread anti- corrosion, anti-stick, and improve joint surface fatigue resisitance.5. Unsetting& thickening to the tube, improvinig the metallurgical structure and enhancing the impact toughness, ensuring comprehansive mechanical properties and the friction weld seals not be broken.Product ParametersNominal sizeDdLDFBending Strength ratio mminmminmmmm NC31-41(2-7/8IF)104.84-1/850.829150100.42.43:1NC35-47120.74-3/450.829150114.72.58:1NC38-50(3-1/2IF)127.0557.22-1/49150121.02.38:1NC44-60152.4657.22-1/49150/9450144.52.49:1NC44-60152.4671.42-13/169150/9450144.52.84:1NC44-62158.86-1/457.22-1/49150/9450149.22.91:1NC46-62(4IF)158.86-1/471.42-13/169150/9450150.02.63:1NC46-65(4IF)165.16-1/257.22-1/49150/9450154.82.76:1NC46-65(4IF)165.16-1/271.42-13/169150/9450154.83.05:1NC46-67(4IF)171.46-3/457.22-1/49150/9450159.53.18:1NC50-67(4-1/2IF)171.46-3/471.42-13/169150/9450159.52.37:1NC50-70(4-1/2IF)177.8757.22-1/49150/9450164.72.54:1NC50-70(4-1/2IF)177.8771.42-13/169150/9450164.72.73:1NC50-72(4-1/2IF)184.27-1/471.42-13/169150/9450169.53.12:1NC56-77196.87-3/471.42-13/169150/9450185.32.70:1NC56-80203.2871.42-13/169150/9450190.13.02:16-5/8REG209.68-1/471.42-13/169150/9450195.72.93:1NC61-90228.6971.42-13/169150/9450212.73.17:17-5/8REG241.39-1/276.239150/9450223.82.81:1NC70-97247.69-3/476.239150/9450232.62.57:1NC70-100254.01076.239150/9450237.32.81:1Detailed Photos Company ProfileXi′an BOBAN Oil Tools Co., Ltd.
