摘　　要：在聚合物加工领域中,人们对拉伸技术并不陌生,在纤维生产中,拉伸技术几乎和尼龙袜的历史一样悠久。双向拉伸生产出的薄膜和塑料瓶在我们日常的生活中也是随处可见。鉴于双向拉伸管材具有良好的综合性能和性价比,几十年来国内外许多研究者开展了大量的研究开发。同时讨论了双向拉伸管的成型方法。Orientation techniques are applied in many plastics applications to achieve enhancements in properties. In fibres, the technology is as old as Nylon stockings, and films and bottles are familiar articles in everyday use. With the improved performance and economics of plastic pipes, much effort has been directed toward biaxially oriented polymer pipes in the past three decades. The equipment for making biaxially oriented pipes is mainly discussed.
