Steam Trap
Assessment Service
Do you perform regular maintenance on your steam traps?
Steam traps have a limited life span, and steam loss can occur due to deterioration of the valve and valve seat over time.
In order to minimize the loss of energy due to steam loss, steam traps must undergo regular assessment and maintenance.
The average defect rate for steam traps is 20 - 25%.
