    Abstract: A cylindrical shell for a tank of a railway tank car is made using roll-forming technology and straight longitudinal weld seams. The cylindrical shell has a longitudinal axis and a uniform cross-sectional shape in a plane normal to the longitudinal axis. The cylindrical shell includes a plurality of elongated segments welded together along weld seams extending parallel to the longitudinal axis of the cylindrical shell. Each elongated segment forms a portion of the cross-sectional shape of the shell and is formed by passing a flat piece of metal plate stock material through a roll-forming machine configured to progressively bend the piece of stock material. In one embodiment, exactly three identical elongated segments, each defining an arc of 120 degrees, are welded together along adjacent longitudinal edges to form a cylindrical shell having a circular cross-section.

    Abstract: Described herein are systems and methods for cryogenic fluid delivery. The systems may include a pressure vessel containing a cryogenic fluid formed of liquid and vapor that is connected to a use device via a withdrawal line. The withdrawal line connects to the cryogenic fluid in the pressure vessel via two routes, a liquid tube and a vapor line. The vapor line may include a back-pressure regulator that opens the vapor line depending on pressure in the system. The withdrawal line may include a pressure relief valve that exerts pressure on the liquid tube. A bypass line may connect the withdrawal line to the liquid tube. The bypass line has a check valve that permits free flow of cryogen from the withdrawal line to the liquid tube via the bypass line while prohibiting cryogen flow from the pressure vessel through the bypass line. The methods employ the systems described herein.

    Abstract translation: 本文描述了用于低温流体递送的系统和方法。 该系统可以包括压力容器,其包含由液体和蒸气形成的低温流体,该低温流体经由抽出管线连接到使用装置。 抽出管线通过两条路线连接压力容器中的低温流体,即液体管道和蒸汽管线。 蒸气管线可以包括背压调节器,其根据系统中的压力打开蒸气管线。 抽出管线可以包括对液体管施加压力的压力释放阀。 旁路管路可以将抽出管线连接到液体管道。 旁路管路具有止回阀,其允许冷冻剂通过旁路管线从排出管线自由流动到液体管道,同时禁止低温冷却剂从压力容器流过旁通管线。 该方法采用本文描述的系统。
