  • Fluid vessel with abrasion and corrosion resistant interior cladding
    Patent number: 9126130
    Abstract: A fluid vessel includes a body structure defining a cavity, an inlet structure defining a first channel, and an outlet structure defining a second channel. The body structure includes an overlay material surrounding the cavity, and includes a metal substrate surrounding the overlay material. The first channel and second channel are provided in fluid communication with the cavity. The inlet structure and outlet structure each include an overlay material surrounding the respective first channel and second channel, and include a metal substrate surrounding the respective overlay material. The overlay material of each of the body structure, the inlet structure, and the outlet structure is fused to the respective metal substrate of the body structure, the inlet structure, and the outlet structure through laser cladding.

  • Fluid pressure vessel employing filter bags
    Patent number: 8640764
    Abstract: A flow through fluid pressure vessel of the type containing filter bags formed by a tubular shell, a one-piece cast bottom closure with an integral outlet port fitting welded to one end of the shell, a one-piece cast combination bulkhead and flange ring welded to the opposite end of the shell, a cast inlet fitting inserted through an aperture in the shell and connected to an inlet opening through the bulkhead and welded to the shell aperture. A cast closure/lid forms an inlet plenum with the bulkhead and is releasably sealed over the flange ring.
