What is the term used for the deposit of calcium carbonate that forms in pipes?

The term used for the deposit of calcium carbonate that forms in pipes is scaling. Scaling is a common issue in water systems where minerals, such as calcium and magnesium, precipitate and accumulate on the inner surfaces of pipes. This buildup can lead to reduced flow rates, increased pressure loss, and potential damage to the infrastructure over time. The process occurs primarily when water is heated or when it evaporates, leading to higher concentrations of these minerals.

Corrosion, on the other hand, refers to the gradual destruction of materials, usually metals, due to chemical reactions, often involving water and oxygen, rather than a deposit of minerals. Tuberculation is a phenomenon typically related to the roughening of pipe surfaces resulting from corrosion, which can create small, localized bumps or tubercles but does not specifically refer to calcium carbonate deposits. Leaching pertains to the process whereby soluble constituents are dissolved and washed away, often used in a different context regarding contaminants or nutrients in soil and water, not within the context of deposits in pipes.
