Condensate recovery pressure loss through piping is the reduction in pressure of the condensate (liquid formed from condensed steam) as it flows through a piping system in a steam distribution or condensate recovery network. This pressure loss occurs due to friction between the condensate and the pipe walls, as well as other factors like pipe fittings, valves, and changes in pipe diameter or direction. This pressure loss is a critical factor in the design and operation of steam and condensate systems, as it affects the efficiency of condensate return and the performance of steam traps and pumps.

Condensate recovery velocity through piping is the speed at which condensed liquid flows through a piping system, typically in steam systems where steam cools and turns back into liquid water. This depends on several factors, including whether the flow is single-phase (liquid only) or two-phase (liquid and flash steam). It’s a critical parameter in designing and operating steam systems to ensure efficient heat transfer, prevent water hammer, and maintain system performance.

The pressure loss of steam in condensate recovery piping is a crucial factor in designing efficient and reliable steam systems. As steam flows through pipes, it encounters frictional resistance and turbulence from the pipe walls and loses pressure. In condensate recovery systems, this pressure loss affects the ability to return condensate to the boiler, potentially leading to energy waste and operational issue.
