摘　　要：在管道不停输封堵作业中,采用钢质管道作为旁通管道存在诸多缺陷,近年发展迅速的超高分子量聚乙烯钢骨架复合管由超高分子量聚乙烯内管、高抗拉强度钢丝和辐射交联聚乙烯热缩胶带复合加工制成,因其优越的抗冲击强度性能,耐磨性能,耐腐蚀、耐药和耐温性能,耐疲劳和耐老化性能,自润滑和不结垢性能,刚性和柔韧性,承压能力而倍受关注。化学介质浸泡与短期静水压强实验结果表明,超高分子量聚乙烯钢骨架复合管的各项性能指标符合SY/T6662-2006行业标准的要求,因此指出了其作为不停输封堵旁通管道的可行性。In the in-line plugging operation of pipeline,steel pipe can not be the best option as the by-pass line.Recently,the rapid developing UHMW-PE steel reinforced pipe draws more and more attentions to its outstanding impact resistance,frictional resistance,corrosion resistance,drug resistance,temperature performance,fatigue durability,self-lubricating characteristic,non-scaling,rigidity,flexibility and loading capacity It is fabricated with UHMW-PE internal pipe,high tensile strength steel cable and radiation cross-linking PE heat shrinkable belt.Solution soaking experiment and short-term hydrostatic pressure test show that the technical indices of UHMW-PE steel reinforced pipe meet the requirements of China Petroleum Standard SY T6662-2006.thus its applicability as by-pass line in the in-line plugging operation of pipeline is proposed.
