    Abstract: Apparatus for internally coating a pipe, comprising a device for heating a pipe as it is internally spray coated and a plurality of inlet rollers and a plurality of outlet rollers for supporting the pipe while it is being heated and longitudinally advanced through the heating device. Each roller is spaced from and adjacent to a corresponding roller in a paired relationship to thereby define a nesting groove located above a gap between each set of paired rollers. A motive device rotates the rollers to rotate the pipe within the nesting grooves of adjacent pairs of rollers. An advancing device longitudinally advances the pipe through the heating device and sequentially along the nesting grooves of adjacent pairs of rollers. The pipe leaving the heating device is heated to a high temperature and has an increased diameter. The supporting surfaces of the rollers are positioned at different distances from the rotational axis of the pipe to retain and align the center line in the heated, expanded pipe sections with the center lines of the colder and smaller diameter pipe sections. This maintaining of the center line of the pipe aligned in a straight line, even at the expanded diameter sections, minimizes vibration of the pipe.

    Abstract translation: 用于内部涂覆管道的装置，包括用于在内部喷涂涂层时加热管道的装置，以及多个入口辊和多个出口辊，用于在加热管道的同时纵向前进通过加热装置。 每个辊与相应的辊以一对关系间隔开并邻近对应的辊，从而限定位于每组成对辊之间的间隙上方的嵌套槽。 动力装置旋转辊子以使管道在相邻辊对的嵌套槽内旋转。 前进装置纵向推进管道穿过加热装置，并且沿相邻辊对的嵌套槽顺序地前进。 离开加热装置的管被加热到高温并具有增加的直径。 辊的支撑表面位于与管的旋转轴线不同的距离处，以将加热的膨胀管段中的中心线与较冷和较小直径的管段的中心线保持和对准。 即使在扩径部分处，直线对准的管的中心线的这种维持也使管的振动最小化。
