| Abstract: | In this paper,with the help of classical mechanics such as elasticity mechanics and structural mechanics,the theoretical calculation on the related connection performance of 20in-ZSB thread casing is carried out.The calculation includes: self-locking of threaded connection,force torque of tightening,the required cylinder number of tightening,resistance to tensile strength,resistance to flexural strength,resistance to internal pressure strength and so on.The calculated results show that: ZSB thread casing has a stronger extrusion performance,tensile,flexural load performance and a higher disassembly and assembly efficiency.Moreover,the calculation method and mechanical model are established,which have a certain reference value to the product design and calculation of the future of special thread oil casing. |
