    How It Works: Pressure Loss | Schlumberger Products

    Jan 09, 2018 · Pressure loss that occurs along the direction of flow in a pipe is caused by fluid friction—both internal in the fluid itself and with the piping surfaces—piping restrictions, or sudden changes in the geometry of the flow path. Thus, pressure loss is directly related to fluid velocity, specific gravity, viscosity, and the pipe interior's size, shape, and roughness.

  • Mistakes and Misconceptions in Valve Leak Testing

    Mistakes and Misconceptions in Valve Leak Testing

    Normally, valves are pressure tested by the factory to check for leaks before they're shipped. The type and method of testing conforms to one or more of many different standards. The purpose of these tests and the expected results are often misunderstood and misapplied, resulting in unnecessary delays and unanticipated costs.
