摘要： A corrosion resistant gas cylinder and gas delivery system includes an electroless nickel-phosphorous layer overlying the inner surface of a steel alloy cylinder. The nickel-phosphorous layer has a thickness of at least about 20 micrometers and a porosity of no greater than about 0.1%. The electroless nickel-phosphorous layer has a phosphorous content of at least about 10% by weight and a surface roughness of no greater than about 5 micrometers. Prior to introducing liquefied gas into the gas cylinder, a cleaning process is carried out using a two-step baking process to clean the surface of the nickel-phosphorus layer. The nickel-phosphorous layer substantially reduces the contamination of liquefied corrosive gasses stored in the gas cylinder by metal from the steel wall surface underlying the nickel-phosphorous layer. Metal contamination levels of less than about 55 ppb of iron, 10 ppb of chromium, and 5 ppb of nickel by weight can be maintained in liquefied corrosive gasses stored for an extended period of time in the electroless nickel-phosphorus plated gas cylinder.

摘要翻译： 耐腐蚀气瓶和气体输送系统包括覆盖钢合金圆筒内表面的化学镀镍 - 磷层。 镍 - 磷层具有至少约20微米的厚度和不大于约0.1％的孔隙率。 无电镀镍磷层的磷含量为至少约10重量％，表面粗糙度不大于约5微米。 在将液化气引入气瓶之前，使用两步烘烤工艺进行清洁处理以清洁镍 - 磷层的表面。 镍 - 磷层通过金属从镍 - 磷层下面的钢壁表面大大减少储存在气瓶中的液化腐蚀性气体的污染。 在化学镀镍 - 磷电镀气瓶中长时间储存的液化腐蚀性气体中，可以维持小于约55ppb的铁，10ppb的铬和5ppb的镍的金属污染水平。

摘要： A valve device that is securable to a cylinder includes a housing with a central passage in fluid communication with a first connection port that connects with a cylinder, and a second connection port including a passage that is in fluid communication with the central passage. The second connection port is configured to connect with a fluid flow line. A valve member is disposed within the second connection port and includes a movable member that engages with a seat to provide a fluid tight seal for the valve member in a closed position. The movable member is configured to be moved away from the seat so as to open the valve member and permit fluid to flow from the central passage of the valve housing around the movable member and through the second connection port while substantially preventing a backflow of fluids from a location external to the valve housing into the central passage.
