Product DescriptionProduct IntroductionThe toothed three-cone rotary drill bit is a three-cone rotary drilling tool with tungsten cobalt alloy teeth (referred to as "toothed teeth") as the rock-breaking unit. It is mainly used in hard rock layer drilling scenarios such as oil drilling and geological exploration. Its core advantage lies in achieving a "shearing + crushing" compound rock-breaking effect through super-hard alloy teeth embedded in the tooth wheel, which extends the service life by 3 to 5 times compared to traditional steel-toothed drill bits.Structural featuresThree-wheel system:Three conical toothed wheels, symmetrically distributed at 120°, achieve synchronous self-rotation and revolution through a bearing system, ensuring uniform distribution of drilling pressureTooth setting technology:Tooth type: A combination layout of wedge-shaped teeth, conical teeth and spherical teethMaterial:YG8/YG11C tungsten-cobalt alloy, with a hardness of over HRA90Inlaying technique:Double fixation with vacuum brazing and interference fitAuxiliary system:High-pressure mud nozzles (3-6 units) are used for rock cuttings cleaningThe sealed bearing structure (metal/rubber seal) ensures the lubrication systemTubing & casing couplingspup jointTubing converterThe oil pipe coupling is a method of connecting two oil pipes through internal and external threads. All types of oil pipe joints have internal threads, which are called internal thread forms. These thread forms are usually machined so that they can be connected to the external threads of the pipe, which are called external thread forms.The oil pipe joint is strictly designed in accordance with the API 5CT specification. There are two types of pipe joints widely used in the pipe joint manufacturing industry, namely:Non-upsetting pipe jointExternal thickened pipe jointOil and casing short sections are produced and processed in accordance with the "API SPEC 5CT Specification", and the materials include steel grades such as J55, K55, N80, N80-1, N80-Q, L80, P110, etc. Oil and casing couplings include two types: flat type and externally thickened type. Its thread processing is completed in one go by using CNC lathes and imported forming tools, ensuring the universality and interchangeability of the threads. The detection means are complete. A full set of thread single-item measuring instruments including taper, pitch, tooth height and thread profile are adopted. The products have passed the appraisal of the Petroleum Pipe Quality Supervision and Inspection and Testing Center of China National Petroleum Corporation.The Adapter Sub/Crossover Sub is a key connection component in the field of oil drilling and production. It is used to convert the threaded interfaces of tubing/casing of different specifications and types, solving the connection problems caused by the mismatch of thread type, size or thickening form between pipe strings. ?Youdaoplaceholder0 EU (outer thickened) ?
