    • The present invention generally relates to apparatus and methods for expanding a tubular. In one embodiment, an expander tool includes a body having at least one recess therein. An expansion assembly disposable in the at least one recess includes a piston that outwardly extends from the body in response to a radially outward force. The expansion assembly includes one or more rollers disposed on a shaft such that the rollers rotate at different speeds. In order to improve a rolling ratio, the shaft is arranged on the piston at an outward angle relative to a longitudinal axis of the tool. The expansion assembly is disposed along the tool at a skew to provide tractoring and reduce slippage due to axial movement. A bearing adjacent the roller and rotationally secured to the roller reduces roller heating and wear. In another aspect, methods for expanding a tubular within a wellbore are provided.
    • 本发明一般涉及用于使管状物膨胀的装置和方法。 在一个实施例中,膨胀器工具包括其中具有至少一个凹部的主体。 在该至少一个凹部中一次性的膨胀组件包括响应于径向向外的力而从主体向外延伸的活塞。 膨胀组件包括设置在轴上的一个或多个辊,使得辊以不同的速度旋转。 为了提高轧制比,轴相对于工具的纵向轴线以向外的角度布置在活塞上。 膨胀组件沿着工具以歪斜方式设置以提供牵引并且减少由于轴向运动引起的滑动。 靠近滚筒并旋转地固定到滚子的轴承减少了滚筒加热和磨损。 在另一方面,提供了用于在管井内扩张管的方法。

    • A gas turbine having a device and a further device is provided. The device includes an outer casing, an inner casing and a seal ring. The outer casing and the inner casing are arranged in such a way that a cooling duct is formed between each other. The seal ring is arranged between the outer casing and the inner casing in such a way that the seal ring seals the cooling duct from an environment surrounding the outer casing. The device and the further device are mounted together such that working fluid is flowable from the further device to the device. Furthermore the device includes a rotatable shaft and the further device includes a further rotatable shaft, wherein the rotatable shaft and the further rotatable shaft are mechanically decoupled from each other, and wherein the seal ring exclusively abuts against the inner casing and against the outer casing of the device.
    • 提供具有装置和另一装置的燃气轮机。 该装置包括外壳,内壳和密封环。 外壳和内壳以彼此形成冷却管道的方式排列。 密封环设置在外壳和内壳之间,使得密封环将冷却管道与围绕外壳体的环境密封。 装置和另外的装置被安装在一起,使得工作流体可以从另外的装置流向装置。 此外,该装置包括可旋转的轴,并且另一装置包括另一可旋转的轴,其中可旋转轴和另一可旋转轴在机械上彼此分离,并且其中密封环专门靠在内壳上并抵靠外壳 装置。
