  2. Ductile iron pipe - Wikipedia

    en.wikipedia.org/wiki/Ductile_iron_pipe

    Section of DICL pipe (ductile iron concrete lined), commonly used for utility water mains, showing iron casing, concrete lining, and textured polymer protective coatings on the inner and outer surfaces. Ductile iron pipe is pipe made of ductile cast iron commonly used for potable water transmission and distribution. [1]

  3. Cement-mortar lined ductile iron pipe - Wikipedia

    en.wikipedia.org/wiki/Cement-mortar_lined...

    Cement-mortar lined ductile iron pipe is a ductile iron pipe with cement lining on the inside surface, and is commonly used for water distribution. Cement-mortar lined ductile iron pipe is governed by standards set forth by DIPRA ( Ductile Iron Pipe Research Association ), and was first used in 1922 in Charleston, South Carolina .

  4. Plumbing - Wikipedia

    Water systems of ancient times relied on gravity for the supply of water, using pipes or channels usually made of clay, lead, bamboo, wood, or stone. Hollowed wooden logs wrapped in steel banding were used for plumbing pipes, particularly water mains. Logs were used for water distribution in England close to 500 years ago.

  5. Cast iron pipe - Wikipedia

    en.wikipedia.org/wiki/Cast_iron_pipe

    It was historically used as a pressure pipe for transmission of water, gas and sewage, and as a water drainage pipe during the 17th, 18th, 19th and 20th centuries. In many modern applications, cast iron pipe has been replaced by ductile iron pipe, but this newer product is still often loosely referred to by the older historical name.

  6. Drain-waste-vent system - Wikipedia

    en.wikipedia.org/wiki/Drain-waste-vent_system

    A sewer pipe is normally at neutral air pressure compared to the surrounding atmosphere.When a column of waste water flows through a pipe, it compresses air ahead of it in the system, creating a positive pressure that must be released so it does not push back on the waste stream and downstream traps, slow drainage, and induce potential clogs.

  8. Backflow prevention device - Wikipedia

    en.wikipedia.org/wiki/Backflow_prevention_device

    Water pressure may fail or be reduced when a water main bursts, pipes freeze, or there is unexpectedly high demand on the water system (for example, when several fire hydrants are opened). Reduced pressure in the pipe may allow contaminated water from the soil, from storage, or from other sources to be drawn up into the system.

  9. HDPE pipe - Wikipedia

    en.wikipedia.org/wiki/HDPE_pipe

    HDPE pipe is a type of flexible plastic pipe used to transfer fluids and gases.It is often employed for replacing aging concrete or steel main pipelines.Constructed from the thermoplastic HDPE (high-density polyethylene), it has low permeability and robust molecular bonding, making it suitable for high-pressure pipelines.
