  2. Cast iron pipe - Wikipedia

    en.wikipedia.org/wiki/Cast_iron_pipe

    In cast iron pipe, the graphite forms flakes during the casting process, when examined under a microscope. Cast iron pipe was superseded by ductile iron pipe, which is a direct development, with most existing manufacturing plants transitioning to the new material during the 1970s and 1980s. Ductile iron pipe is different than cast iron, because ...

  3. Trench drain - Wikipedia

    en.wikipedia.org/wiki/Trench_drain

    Like in the cast-in-place method, a metal frame is attached to the form and concrete is poured and finished in a factory atmosphere. The advantage to the pre-cast trench drain is again time savings—big time savings at the job site. Pre-cast trench drains made of a polymer concrete are also more sturdy and reliable than cast-in-place trenches.

    Cast iron and ductile iron pipe was long a lower-cost alternative to copper before the advent of durable plastic materials but special non-conductive fittings must be used where transitions are to be made to other metallic pipes (except for terminal fittings) in order to avoid corrosion owing to electrochemical reactions between dissimilar ...

    Flexible rubber sleeves are used to connect this cast-iron and copper DWV installation. Cast iron DWV pipe and fittings are still used in premium construction because they muffle the sound of wastewater rushing through them, [21]: 149 but today they are rarely joined with traditional lead joints.

  7. Rain gutter - Wikipedia

    en.wikipedia.org/wiki/Rain_gutter

    Cast iron gutters were introduced in the late 18th century as an alternative to lead. Cast iron enabled eaves gutters to be mass-produced: they were rigid and non-porous while lead could only be used as a liner within timber gutters. Installation was a single process and didn't require heat. [26] They could be attached directly to the fascia board.

  8. Cast-iron architecture - Wikipedia

    en.wikipedia.org/wiki/Cast-iron_architecture

    Cast iron is not a good structural material for handling tension or bending moments because of its brittleness and relatively low tensile strength compared to steel and wrought iron. However, cast iron does have good compressive strength and was successfully used for structural components that were largely in compression in well-designed ...

  9. Drain (plumbing) - Wikipedia

    en.wikipedia.org/wiki/Drain_(plumbing)

    A drain cover is a cover with holes (e.g. a manhole) or a grating used to cover a drain, to prevent unwanted entry of foreign objects, or injury to people or animals. It allows drainage of liquids but prevents entry from large solid objects, and thus acts as a coarse filter. A sink drain cover is a drain cover used to cover the sink drain.
