In this paper, the series of the pressure grade of the steel reinforced plasticspipe and the surface processing technique of the special steel wire for the newframework are discussed.
本课题主要研究内容是研究钢骨架塑料复合管管道压力等级的系列化以及新型骨架专用钢丝的表面处理技术，通过构建理论模型，模拟计算复合构造的管体强度，并根据分析模拟结果，确定钢骨架钢丝的网格间距、钢丝直径及强度类型等，从而提高管道的承压能力，提高压力等级以便拓宽产品应用领域。
