For devices that are used intermittently, have you protected them with nitrogen?
Thread Content
Cold exchange equipment that is taken out of use intermittently will suffer from corrosion in a naturally humid environment, which can easily lead to perforations and failure of the tube bundles; however, filling the area with nitrogen to create an environment free from corrosion can effectively extend the lifespan of the tube bundles.
Charge to ensure pressure. Below requirements, supplementary
We don’t have individual devices; for entire systems, after they are taken out of service for maintenance and their openings are sealed, we also use nitrogen protection to keep them in that state for an extended period of time.
Based on this report, it seems that filling ordinary equipment with nitrogen still has benefits
The steam system is filled with instrument air or nitrogen for protection when not in use
A slight positive pressure of dry nitrogen, which prevents water vapor and oxygen from entering, can effectively reduce corrosion damage
Equipment stored in the warehouse for long periods requires nitrogen protection, and the heaters of the motors need to be powered on to prevent the motors from getting damp
The cost is not low, but it’s worth promoting
Compared to the damage to the equipment, this cost is not significant
