Limescale is a hard, chalky deposit, consisting mainly of calcium carbonate (CaCO 3). It often builds up inside kettles , boilers , and pipework, especially that for hot water. It is also often found as a similar deposit on the inner surfaces of old pipes and other surfaces where hard water has flowed.

Orangeburg pipe (also known as "fiber conduit", "bituminous fiber pipe" or "Bermico" or "sand pipe") is bituminized fiber pipe used in the United States. It is made from layers of ground wood pulp fibers and asbestos fibres compressed with and bound by a water resistant adhesive then impregnated with liquefied coal tar pitch .
Limescale buildup inside a pipe reduces liquid flow through the pipe and reduces thermal conduction from the liquid to the outer pipe shell. Both effects will reduce the pipe's overall thermal efficiency when used as a heat exchanger. Extreme boiler pipe scale buildup Temperature dependence of the solubility of calcium sulfate (3 phases) in ...
It typically consists of a hot water pipe running behind a fireplace or stove (rather than hot water storage), and has no facility to limit the heating. Modern wetbacks may run the pipe in a more sophisticated design to assist heat-exchange. These designs are being forced out by government efficiency regulations that do not count the energy ...
The pipe in the tunnel has an inside diameter of 22 feet (6.7 m). [4] The East Side tunnel was the largest sewer construction project ever undertaken by the City of Portland. A contractor, Kiewit-Bilfinger Berger (KBB), used a tunnel boring machine that was 300 feet (91 m) long and had a cutting head that was 25 feet (7.6 m) in diameter. In ...

18 sizes of Palmer-Bowlus flumes have been developed - in line with the common pipe sizes to which they would be adapted - from 4-inches to 72-inches. In practice, though, it is uncommon to see Palmer-Bowlus flumes greater than 24-inches in size. [3] Under average flow conditions, the Palmer-Bowlus flume is accurate to within 3-5%.
