  2. Ductile iron pipe - Wikipedia

    en.wikipedia.org/wiki/Ductile_iron_pipe

    In the late 1950s, ductile iron pipe was introduced to the marketplace, featuring higher strength and similar corrosion resistance compared to cast iron. [10] According to a 2004 study, an expected lifespan of 100 years is likely for ductile iron pipe, based on test results, field inspections and in-service operations over 50 years. [11]

    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 .

  7. Iron pipe size - Wikipedia

    en.wikipedia.org/wiki/Iron_pipe_size

    During the IPS period, pipes were cast in halves and welded together, and pipe sizes referred to the inside diameters. [1] The inside diameters under IPS were roughly the same as the more modern Ductile Iron Pipe Standard (DIPS) and Nominal Pipe Size (NPS) Standards, and some of the wall thicknesses were also retained with a different ...

  8. Pipe (fluid conveyance) - Wikipedia

    en.wikipedia.org/wiki/Pipe_(fluid_conveyance)

    Designating the outside diameter allows pipes of the same size to be fit together no matter what the wall thickness. For pipe sizes less than NPS 14 inch (DN 350), both methods give a nominal value for the OD that is rounded off and is not the same as the actual OD. For example, NPS 2 inch and DN 50 are the same pipe, but the actual OD is 2.375 ...

    en.wikipedia.org/wiki/Ductile_iron

    Ductile iron is used in many piano harps (the iron plates which anchor piano strings). Ductile iron is used for vises. Previously, regular cast iron or steel was commonly used. The properties of ductile iron make it a significant upgrade in strength and durability from cast iron without having to use steel, which is expensive and has poor ...
