  2. Boiler blowdown - Wikipedia

    en.wikipedia.org/wiki/Boiler_blowdown

    A pipe near the bottom of the blowoff tank maintains a water level below the blowdown entry point and allows cooler water remaining from earlier blowdown events to drain from the tank first. Two bottom blowdown valves are often used in series to minimize erosion. One valve serves as the sealing valve, and the other as the blowdown valve.

  3. Subsea valves - Wikipedia

    en.wikipedia.org/wiki/Subsea_valves

    Subsea valves are used to isolate or control the flow of material through an undersea pipeline (submarine pipeline) or other apparatus.Most commonly used to transport oil and gas, they are designed to function in a sub-marine environment, withstanding the effects of raised external pressure, salt-water corrosion, and bubbles or debris in the material carried.

  4. Cavitation - Wikipedia

    en.wikipedia.org/wiki/Cavitation

    When water flows over a dam spillway, the irregularities on the spillway surface will cause small areas of flow separation in a high-speed flow, and, in these regions, the pressure will be lowered. If the flow velocities are high enough the pressure may fall to below the local vapor pressure of the water and vapor bubbles will form.

  5. Water hammer - Wikipedia

    en.wikipedia.org/wiki/Water_hammer

    To keep water hammer low, pipe-sizing charts for some applications recommend flow velocity at or below 1.5 m/s (4.9 ft/s). Fit slowly closing valves. Toilet fill valves are available in a quiet fill type that closes quietly. Non-slam check valves do not rely on fluid flow to close and will do so before the water flow reaches significant velocity.

  6. Piping and plumbing fitting - Wikipedia

    en.wikipedia.org/wiki/Piping_and_plumbing_fitting

    A trap primer automatically injects water into a trap, maintaining a water seal to keep sewer gas out of buildings. It must be installed in an easily accessible place for adjustment, replacement, and repair. A trap primer, a specialized valve, is usually connected to a clean-water supply in addition to a DWV system. [20]

  7. Tap (valve) - Wikipedia

    en.wikipedia.org/wiki/Tap_(valve)

    A single temperature tap is commonly found in a commercial or public restroom where the temperature of the water will be controlled by a separate temperature regulating valve that mixes hot and cold water. The regulating valve may be under the handwashing sink or in a separate mechanical room or service closet.

  8. Ductile iron pipe - Wikipedia

    en.wikipedia.org/wiki/Ductile_iron_pipe

    Protective internal linings and external coatings are often applied to ductile iron pipes to inhibit corrosion: the standard internal lining is cement mortar and standard external coatings include bonded zinc, asphalt or water-based paint. In highly corrosive environments loose polyethylene sleeving (LPS) to encase the pipe may also be used.

  9. Sewerage - Wikipedia

    en.wikipedia.org/wiki/Sewerage

    One option is the application of a cementitious material based on calcium aluminate cement, after a cleaning of the corroded structure to remove loose material and contaminants in order to expose a sound, rough and clean substrate. Depending on the concrete condition and contamination, the cleaning can range from simple high pressure jet water ...
