  • Publication number: 20240142333
    Abstract: A portable, case-enclosed pressure test manifold, configured to support both pneumatic and hydrostatic pressure testing, and comprising a downstream fluid path (e.g., a system test gauge, a ball valve, a system test port, a system relief valve, and other components/piping) and an upstream fluid path (e.g., a low-pressure gauge, a high-pressure gauge, and various other components/piping). A regulator and/or the ball valve selectively operate the downstream fluid path, defining a hydrostatic pressure testing path, to receive a liquid; and the upstream fluid path in combination with the downstream fluid path, defining a pneumatic pressure testing path, to receive a gas. Manifold components are pressure rated based on use and are ASME Code B31.3 compliant. Properly rated flexible hoses connect with either of the pneumatic or the hydrostatic pressure testing paths of the manifold. The case includes parking receptables and a carrying handle configured to stow the hose during transport.

  • Publication number: 20210404926
    Abstract: A portable, case-enclosed pressure test manifold, configured to support both pneumatic and hydrostatic pressure testing, and comprising a downstream fluid path (e.g., a test gauge, a vent valve, a system test port, a relief valve, and various other high-pressure rated components/piping) and an upstream fluid path (e.g., a low-pressure gauge, a high-pressure gauge, and various other low-pressure rated components/piping). A regulator and/or the vent valve selectively operate the downstream fluid path, defining a high-pressure fluid path, to receive a liquid; and the upstream fluid path in combination with the downstream fluid path, defining a low-pressure fluid path, to receive a gas. Manifold components are pressure rated based on use and are ASME Code B31.3 compliant. A flexible hose connects with either of the low-pressure fluid path and the high-pressure fluid path of the manifold. The case includes parking receptacles and a carrying handle configured to stow the hose during transport.
