  • Patent number: 11229947
    Abstract: A method of manufacturing a valve body having one or more corrosion-resistant internal surfaces. The method involves performing a casting process, which includes pouring a first material into a mold box, to produce a valve body casting made of the first material. During the casting process, a layer of a second material is formed on one or more internal surfaces of the valve body casting, the second material having a higher corrosion resistance than the first material, by: (1) applying, with an additive manufacturing technique, the second material to one or more external surfaces of a core, and (2) inserting the core into the mold box. A portion of the first material binds to the second material on the one or more external surfaces of the core while the first material is poured into the mold box.

  • Patent number: 11192212
    Abstract: A method is provided of custom manufacturing a valve body having an initial valve body configuration having a first end connection and a second end connection. The method includes adding material to the first end connection using a first additive manufacturing process to create at least a portion of a custom first end connection configuration, and the custom first end connection configuration is different than an initial first end connection configuration. The method further includes adding material to the second end connection using a second additive manufacturing process to create at least a portion of a custom second end connection configuration, and the custom second end connection configuration is different than an initial second end connection configuration.
