Skid-mounted equipment refers to an assembly of devices secured to a base frame constructed from angle steel or I-beams; historically, these units could be moved into position using pry bars (though lifting equipment is now universally employed). This equipment assembly remains exposed-a characteristic that distinguishes it from enclosed pressure-regulating cabinets. In fact, numerous other types of skid-mounted equipment exist, such as generator sets, air compressors, and heat exchange units.
Furthermore, "skid-mounting" denotes a self-contained, integrated assembly in which components-such as valves and pumps-have already been pre-installed.
Consequently, when connecting this unit to other parts of a larger system, there is no need to install additional intermediate components (such as valves or instrumentation); a simple pipeline connection suffices.
Essentially, skid-mounting represents a specific method of integrating equipment components within a structural framework to form a unified assembly.
