What is the consequence of having condensate present in steam lines?

Having condensate present in steam lines can lead to water hammer, which is a significant issue in steam systems. Water hammer occurs when condensed water collects in low points of the piping. When the steam pressure increases, the steam can cause the liquid water to be violently accelerated, leading to shock waves that can create banging noises and potentially cause serious damage to the pipes and fittings. This phenomenon happens because the sudden change in momentum when steam hits the condensate creates stress on the piping system.

In addition to causing loud bangs and potential pipe damage, the presence of condensate in the steam lines can disrupt the efficient transfer of heat. Instead of the steam being able to carry heat freely, the presence of water can impede flow and thermal effectiveness. However, in this specific context, the primary and most immediate consequence associated with condensate in steam lines is water hammer, underscoring the importance of proper drainage and circulation in steam systems to prevent such issues from occurring.
