Desiccant bags protect pressure vessels from corrosion during storage and transportation. These bags are filled with desiccant materials, such as calcium chloride. These materials are highly effective in absorbing moisture from the air, preventing it from coming into contact with the vessel and causing rust or other forms of corrosion.
However, pressure vessels are susceptible to corrosion, especially during transportation. Moisture in the air can cause rust to form on the surface of the vessel, which can weaken the metal and eventually lead to leaks or even catastrophic failure.
