FAQ's
What is the use of a condensate pot in steam lines?
A condensate pot collects and holds condensate to protect instruments from high-temperature steam.
Where is the condensate pot installed?
What are the standard sizes of condensate pots?
They are typically available in 2”, 3”, 4” diameters with 2 to 6 ports, depending on system requirements.
What is the difference between seal pot and condensate pot?
Seal pot is used in situations where the line fluid is corrosive or viscous to the point where it can be clogged. Condensate pots are primarily used to increase the accuracy of differential pressure flow measurement in steam (or vapor) applications.
What is the purpose of a condensate system?
The fundamental functions include supplying low-pressure water to the deaerator across all operating conditions and providing attemperation water to desuperheater sprays for the LP bypass (if present) and the auxiliary steam system.
