Finite Element Analysis of Special Thread for Marine Production Riser Joint
摘要
Abstract
In order to adapt to the harsh conditions of marine underwater production riser,a kind of top tensioning production riser threaded joint was designed,and the related mechanical analysis to this threaded joint were conducted by adopting finite element contact analysis model. Calculated and compared coupling thread and pipe body strength by Abaqus finite element software, simulated the make-up process of riser, calculated the best make-up torque, and simulated the sealing performance of the model under four kinds of loads, such as upper buckle torque, upper buckle and internal pressure, upper buckle and stretch, upper buckle and stretch and internal pressure. Finite element analysis results indicated that the sealing surface contact pressure increases with the increase of internal pressure, the uniaxial tensile load makes the sealing surface contact pressure reduce, the contact pressure on the sealing surface shows an increasing trend when the tensile load and internal pressure are combined, but the increase extent is smaller than that of the internal pressure. The strength of this marine production vertical pipe special threads is better than pipe body, the sealing performance is reliable and meets the design requirements.关键词
