    • A flexible, fiber reinforced pipe has been invented for conveying fluids. The pipe is flexible enough to be spoolable, even under winter temperature conditions. The pipe can contain pressure, when buried, unrestrained and bent. The pipe exhibits impact resistance under normal handling and can be formed using a continuous process, such that it can be manufactured as it is being laid. A flexible, fiber reinforced pipe includes an inner tubular liner having an inner surface and an outer surface; a first layer of reinforcing fibers helically wrapped about the inner liner and in direct contact therewith; an outer layer of reinforcing fibers helically wrapped about an underlying layer of reinforcing fibers and in direct contact therewith; and an outer tubular sheath applied over the outer layer in direct contact therewith.
    • 已经发明了用于输送流体的柔性纤维增强管。 即使在冬季温度条件下,该管道也足够灵活,可以使其脱线。 管道可以承受压力,埋藏时,无限制和弯曲。 该管在正常操作下具有耐冲击性,并且可以使用连续的方法形成,使得其可以按照正在铺设的方式制造。 柔性纤维增强管包括具有内表面和外表面的内管状衬垫; 螺旋缠绕在内衬上并与其直接接触的第一层增强纤维; 螺旋缠绕在增强纤维的下层并与其直接接触的增强纤维的外层; 以及施加在外层上的与其直接接触的外管状护套。

    • A pipe coupling and connector for use with composite pipe, and a method of coupling the end of composite pipe are disclosed. The coupling or connector has a cylindrical inner support with a gripping surface, a means for preventing axial movement of slips that are disposed around the gripping surface, and a coupling connector. The slips form an assembly with an outer frustoconical surface and an inner gripping surface. A hollow outer sleeve with a surface that corresponds to the frustoconical surface is used to drive the slips radially inwards so that the wall of the pipe is both compressed and gripped by the coupling. A retaining member holds the outer sleeve in a fixed position relative to the slips. The coupling, connector and method of this invention provide the structural integrity needed to ensure that the end of the pipe meets or exceeds the design ratings of the pipe.
    • 公开了一种用于复合管的管接头和连接器,以及联接复合管端部的方法。 联接器或连接器具有带有抓握表面的圆柱形内部支撑件,用于防止设置在抓握表面周围的滑移件的轴向移动的装置和联接连接器。 滑块形成具有外截头圆锥形表面和内夹紧表面的组件。 具有对应于截头圆锥形表面的表面的中空外套筒用于径向向内驱动滑动件,使得管道的壁都被联接器压缩和夹持。 保持构件将外套保持在相对于滑移件的固定位置。 本发明的联接器,连接器和方法提供了确保管的端部达到或超过管的设计额定值所需的结构完整性。
