摘要
热塑性复合材料管(Thermoplastic Composite Pipes,TCP)因为优异的力学和化学性能,包括易弯曲、强度高、耐腐蚀等,在石油与天然气的开采和运输过程中得到了越来越广泛的应用。在深水油气田的开发过程中,管道自重和输送压力的增加对海洋柔性立管的结构设计提出了更加具有挑战性的要求。采用ABAQUS有限元软件研究管道内压承载力和拉伸承载力与管道增强层缠绕角度的关系,进而针对假定的内压荷载和拉伸荷载对TCP管道增强层进行单角度铺层的截面设计。在此基础上,设计了一种采用多角度铺层的TCP管道结构。研究结果表明,在满足相同的设计内压和设计拉伸荷载的情况下,多角度铺层TCP管道比单角度铺层TCP管道的增强层壁厚更薄,需要的纤维增强单向带材料更少,多角度铺层TCP管道具有更好的经济适用性。研究结果可为热塑性复合材料管生产提供参考。
Due to its excellent mechanical and chemical properties such as light weight,high strength and corrosion resistance,thermoplastic composite pipe(TCP)has been increasingly widely used in oil and gas exploitation and transportation.In the development of deep-water oil and gas fields,the pipeline deadweight and the increase of transportation pressure puts forward more challenging requirements for the structural design of marine compliant riser.In this paper,the ABAQUS finite element software was used to firstly study the relationship between the internal pressure bearing capacity and tensile bearing capacity of the pipeline and the winding angle of the pipeline reinforcement layer.On this basis,the single angle stacking section design was conducted for the TCP reinforcement layer based on the assumed internal pressure load and tensile load.Then,based on the single angle stacking section design,a multi angle stacking TCP structure was designed.The study results show that under the condition of meeting the same designed internal pressure and designed tensile load,the wall thickness of the reinforcement layer of the multi angle stacking TCP is thinner than that of the single angle stacking TCP,and the required fiber reinforced unidirectional tape material is less.Therefore,the multi angle stacking TCP has better economic applicability.The study results provide reference for the manufacturing of the thermoplastic composite pipe.
