    • Apparatus for applying chemical plating to inner surfaces of tubular members including a tank for storing a plating solution, a table for supporting a plurality of tubular members to be simultaneously plated, a plating solution distributing member connected to the storage tank via a plating solution supply line mounting a pump, and a plating solution collecting member connected to the storage tank via a plating solution return line. To provide a liquidtight seal, each tubular member to be plated is connected at its plating solution inlet end to the distributing member through a first connector and at its plating solution outlet end to the collecting member through a second connector. Each tubular member supported on the table, which is suitably inclined to allow hydrogen gas to be released through the plating solution outlet end of each tubular member to be plated, is encased in a supporting member formed of insulating material and comprising detachably attached two halves. The plating solution distributing and collecting members are similar in shape, the former having an inverted T-shape and the latter a T-shape. The storage tank is connected to a heater to keep constant the temperature of the plating solution and has a monitoring sample inserted therein to indicate the thickness of the coating.
    • 用于对管状构件的内表面施加化学镀的装置,包括用于储存电镀溶液的罐,用于支撑同时镀覆的多个管状构件的工作台,经由电镀溶液供应管线连接到储存罐的电镀液分配构件 安装泵,以及通过电镀液返回线连接到储罐的电镀液收集构件。 为了提供液密密封,要被电镀的每个管状构件在其电镀液入口端处通过第一连接器连接到分配构件,并且其电镀液出口端通过第二连接器连接到收集构件。 支撑在桌子上的每个管状构件被适当地倾斜以允许通过待镀覆的每个管状构件的电镀液出口端释放氢气被封装在由绝缘材料形成的支撑构件中并且包括可拆卸地连接的两个半部。 电镀液分配和收集部件的形状相似,前者具有倒T形,后者为T形。 储存罐连接到加热器以保持电镀液的温度恒定,并且将监测样品插入其中以指示涂层的厚度。
