1- Quality of The Steam: Process steam shall be dry, air vented and has the required pressure rating.

2- Wrong trap selection: In case the trap is chosen wrong, then this will reduce the efficiency of the steam on process and efficiency of the steam consuming equipment. Means lots of energy.

3- Mistaken Installation of The Trap: In case the trap installed on the line with wrong direction this can block the line and damage both the process and the steam consuming equipment. Float type steam traps are mistaken with the inverted bucket types and are installed upside down in the steam lines. Because of this, steam trap is either get locked or remains as constantly open and causes steam loss.

4- Dirt, Water – Hammer, Freezing: In case of any these has chance to appear on process the traps shall chosen accordingly and necessary improvement shall be done on process lines.

5- Air Accumulations: One of the most important effects of steam for losing the efficiency is the air inside the lines. This air shall be vented otherwise water – hammers can appears and / or heat of the steam will be consumed by useless air which can also block some traps such as thermodynamic steam traps.

6- Differential Pressure: Inlet pressure shall be more then outlet pressure of the trap. In case of an increase on the back line pressure this can damage all system, such as equipments, boiler, traps steam process lines etc.
