What Does Manifold Mean?

A manifold refers to a collection of pipes or a bound header that facilitates the transportation of fluid from one point to another. Manifolds are widely used in the pipeline industry and can be prone to corrosion with prolonged use and fluid-induced wear and tear.


Corrosionpedia Explains Manifold

Manifold systems can be seen in many industrial fluid flow distribution processes, where it is used to distribute a large fluid stream into several smaller, parallel streams – and then collect them into one discharge stream further down the line. Examples of such systems are heat exchangers, irrigation lines, exhaust systems and other fluid processing system components.

Manifolds are primarily made from any of several metallic materials. The most commonly used is ferrous alloys. Aluminum alloys may also be used as a protective coating on ferrous alloys to reduce the occurrence of corrosive reactions. Nonferrous elements, such as nickel and titanium, are used in system components with high flow rate, pressure or performance requirements. In rare cases, ceramics are used to take advantage of their insulating properties.
