What is one way to prevent standing condensate in steam lines?

Ensuring proper sloping of the steam lines is key to preventing standing condensate. When steam travels through pipes, it naturally cools and condenses into water. If the pipes are not appropriately sloped, this condensate can accumulate in low spots, leading to potential blockages, water hammer, and inefficient operation of the steam system. The correct slope allows the condensate to flow back to the steam trap or drainage points, facilitating proper management of the condensate and maintaining system efficiency.

While the other options may contribute to the overall efficiency and effectiveness of a steam system, they do not specifically address the issue of condensate accumulation in the same direct manner that proper sloping does. Insulation can help in maintaining steam temperature, and using shorter pipes or standard fittings might have operational benefits, but without the correct slope, condensate issues are likely to persist.
