    Abstract: In a glass or ceramic-lined reactor vessel for use with corrosive contents, to repair major damage of a nozzle, damaged portions of the nozzle are first removed as by cutting torch, the remaining nozzle neck wall is edge-tapered for welding, a replacement nozzle opening comprising a flange is provided and attached by welding inside and out, any surplus inside bead or rod slag being brought to a conforming surface; the nozzle and adjacent portions of the reactor vessel are sheathed with a metal cover, the metal being from one-eighth to one-half inch, both inclusive, in thickness, and being such as is substantially inert under the conditions of use of the equipment being repaired; the cover comprising essentially an outer face disc and an inner face disc each defining a threaded central opening, a tubular nozzle interior sheath, the ends of the nozzle interior sheath and the inner aspects of the openings of the discs being cooperatively threaded; any space otherwise void between repair sheath and nozzle interior surface being filled with a curable resin filler that is inert and insoluble when cured; the nozzle being drawn securely into place and cooperating deformable chemically gaskets being deformingly seated, by tightening of especially the threaded outer face disc onto the threaded tubular sheath.

    Abstract translation: 在用于腐蚀性物质的玻璃或陶瓷衬里的反应堆容器中，为了修复喷嘴的主要损坏，喷嘴的损坏部分首先通过切割炬被去除，剩余的喷嘴颈壁是边缘锥形用于焊接，替换 通过焊接内部和外部设置并附接包括凸缘的喷嘴开口，任何多余的内部珠或棒渣被带到一致的表面; 反应器容器的喷嘴和相邻部分用金属覆盖物覆盖，金属的厚度为八分之一到二分之一英寸（厚度），并且在使用设备的条件下基本上是惰性的 正在修理 所述盖基本上包括外表面盘和每个限定螺纹中心开口的内表面盘，管状喷嘴内部护套，所述喷嘴内部护套的端部和所述盘的所述开口的内部方面协同地螺纹连接; 在修理护套和喷嘴内表面之间任何空隙，填充有固化的惰性和不溶性固化树脂填料; 通过将特别是螺纹的外表面盘紧固到螺纹的管状护套上，喷嘴被牢固地拉入到位并配合可变形的化学垫圈变形地安置。

    Abstract: In a glass or ceramic-lined reactor vessel for use with corrosive contents, to repair damage of glass lining and surface of a nozzle, damaged portions of the nozzle are cleaned and brought to a sound surface; recess is filled with a curable resin; the nozzle and adjacent portions of the reactor vessel are then sheathed with a two piece metal cover, the metal being such as is substantially inert under the conditions of use of the equipment being repaired; the cover comprising essentially an outer facepiece with a returning flange that sheaths the outer edge of the face flange of the nozzle; and a crimped inner facepiece each being produced or fabricated to define a tubular central extension such that as both pieces are in place they mate to sheath nozzle interior completely; any gap between repair sheath and covered surface being filled with a curable resin filler that is inert and insoluble when cured; the nozzle being held securely in place with cooperating inert gasket engaging the crimped interior face as curable resin is cured.
