Low-Pressure Steam vs. High-Pressure Steam - …

Let's start with a simple fact: low-pressure steam travels faster than high-pressure steam. Surprised? It's true. If the load is the same in both cases, the low-pressure steam will move through the pipes much more quickly than the high-pressure steam. The reason is simple: High-pressure steam fits into a smaller space than low-pressure steam.
