摘要
钻杆是钻探设备中最重要的材料之一,钻杆的质量直接取决于钻杆的加工工艺。对传统的钻杆加工 工艺进行改进,采用中频透热、液压镦厚、摩擦对焊等先进工艺加工生产出的无细扣摩擦焊钻杆,属于优材质高强 度钻杆,质量可靠,并且在很多领域得到越来越广泛的应用。
Seamless frictional welded drilling rod has a high quality and high strength. It is produced by adapting the methods of medium frequency diathermy, hydraulic thickening, frictional welding, quenching and tempering, checking scar and block tensible elongation, with a satisfactory variety of sorts and reliable quality.
