pijplengte

Pijplengte is a Dutch term that denotes the length of a pipe or a pipe segment, measured along the pipe’s axis from one end to the other. It refers to the linear distance between defined points in a piping system, such as between flanges, valves, fittings, or section boundaries. The concept is used across plumbing, water supply, gas networks, and industrial piping.

Knowing the pipelength is important for several reasons. It determines the internal volume of a pipe segment (volume equals cross-sectional area times length) and influences hydraulic calculations, including pressure drop and transit time. It also affects structural considerations, such as insulation, supports, and thermal expansion, since longer segments may require different handling than shorter ones. In design and construction, the pipelength helps planners place components efficiently and plan maintenance access.

In practice, pipelength is measured along the pipe axis, typically from the inside faces of end connections or flange faces, depending on the applicable standard or project specification. It is usually specified in project drawings and accompanying installation and testing documents. While the basic idea is straightforward, the exact definition can vary by industry or standard, so it is important to refer to the relevant technical documents for precise measurement.

Etymology: the word combines Dutch pijp (pipe) and lengte (length).
