What is the primary purpose of a steam blanket lay-up?

The primary purpose of a steam blanket lay-up is to prevent moisture accumulation. In a steam system, moisture can lead to various problems such as corrosion, scaling, and decreased efficiency in boilers and other components. By utilizing a steam blanket lay-up, a continuous layer of steam is maintained in the system, which helps to displace and prevent condensation from forming. This is particularly important during periods of inactivity when the system is not in operation, as it preserves the internal condition of the equipment.

Maintaining moisture-free conditions is crucial because any excess water or moisture can lead to deterioration of the system, potentially causing damage or requiring extensive maintenance when it is brought back online. Thus, the prevention of moisture accumulation is essential for extending the operational life and reliability of steam systems.
