摘要:
为了适应海洋水下生产立管的苛刻工况,设计了一种顶端张紧式生产立管螺纹接头,并采用有限元接触分析模型对该接头进行了相关的力学分析。通过Abaqus有限元软件计算对比了接箍螺纹与管体强度,模拟立管的上扣过程,计算最佳上扣扭矩,研究了该模型在上扣扭矩、上扣和内压、上扣和拉伸、上扣和拉伸及内压四种载荷下的密封性能。有限元分析结果表明,密封面接触压力随内压的增加而增加,单轴拉伸载荷使得密封面的接触压力有所减小,拉伸载荷和内压共同作用时密封面上的接触压力呈增加趋势,但是增加的幅度要比仅受内压作用时小。该海洋生产立管特殊螺纹的强度优于管体,密封性能可靠,满足设计要求。
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.
