Engineer's Selection Guide: Steam Traps

Steam traps discharge condensate and non-condensable gases while retaining live steam. Selection depends on the trap type (mechanical, thermodynamic, thermostatic), load, pressure, and whether continuous or intermittent drainage is required. Proper sizing prevents premature failure and energy loss.

Frequently Asked Questions

Q: What is a steam trap used for?

A: A steam trap removes condensate and air from steam systems while preventing live steam loss, improving energy efficiency and protecting equipment.

Q: What are the main steam trap types?

A: The three families are mechanical (float), thermodynamic (disc), and thermostatic (bellows/bimetallic), each suited to different load and pressure conditions.

Guidance reflects general engineering practice for steam traps; confirm against the project specification and applicable standards before procurement.
