    • A system and method for winding fibers onto an article is disclosed. The system includes a winding station having a controllable speed of rotation. The winding station has at least one fiber bobbin mounted on it. A rotation sensor is rotationally coupled to the winding station. The system includes a conveyor having a controllable speed and which is adapted to move the article axially through the winding station. A speed sensor, adapted to measure an axial speed of motion of the article through the winding station is positioned near the winding station. The system includes a controller adapted to operate the winding station at a rotational speed corresponding to the axial speed of motion, so as to apply the fibers to the article in a predetermined helical pattern. In one example, the helical pattern is held to a lay angle having a tolerance within one-half degree. In the method, the rotational speed of the winding station is adjusted to correspond to the axial motion of the article so that the fibers are wound in a predetermined helical pattern. In one example of the method, the lay angle of the fibers is held to within a tolerance of about one half degree. In another example, the lay angle is selected to correspond to the axial position of the article within the winding station.
    • 公开了一种将纤维缠绕到制品上的系统和方法。 该系统包括具有可控旋转速度的卷绕站。 卷绕站具有安装在其上的至少一个纤维线轴。 旋转传感器旋转地联接到卷绕站。 该系统包括具有可控制速度的输送机,其适于使制品沿轴向移动通过卷绕站。 用于测量穿过卷绕站的物品的轴向运动速度的速度传感器位于卷绕站附近。 该系统包括适于以对应于轴向速度运动的旋转速度操作卷绕站的控制器,以便以预定的螺旋图案将纤维施加到物品上。 在一个示例中,螺旋图案被保持在公差在二分之一内的平角。 在该方法中,卷绕站的旋转速度被调节以对应于制品的轴向运动,使得纤维以预定的螺旋图案缠绕。 在该方法的一个示例中,纤维的铺设角度保持在约半度的容限内。 在另一示例中,铺设角度被选择为对应于卷绕站内的物品的轴向位置。

    • 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。

    • 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。
