UNI KLINGER having various type of steam traps design irrespective to service & criticality

As like,

• Thermodynamic steam trap (UTD)
• Thermostatic steam trap (UTST)
• Bi-metallic steam traps
• Inverted bucket steam trap (UIBT)
• Ball Float steam trap (UFT)

How to select Traps & which parameters can be affect on steam trap performance &it’s efficiency:

Selection on Steam trap:

• Know your service/ application
• Location of trap i.e. reactor/ direct heating/ Indirect heating/ type of equipment coil (Jacketed/ Limpet coil)
• Total Qty of steam/ Condensate (Kg/hr)
• Operating pressure (Kg/cm2 g/ Bar g)
• Steam Inlet line size (NB/mm/ DN)
• Design Pressure drop of equipment (Reactor/ heat exchanger)
• Back pressure (Kg/cm2 g/ Bar g)
• Differential Pressure (Kg/cm2 g/ Bar g) which Inlet of traps & back pressure of downstream of trap (i.e. Delta P)
• Moreover, area where trap to be installed like atmospheric condition so that material of trap can be selected
• Sight Glass require wherever trap is in close system

Parameters which can affect on steam trap performance:

• Back pressure
• Under sizing of steam trap against high load
• Material of selection
• Customer don’t have exact detail of plant
• Wrong selection
• Wrong installation (Vertical/ Horizontal)
• Wrong differential selection of trap/ model
• End connection of trap against MOC of trap

For e.g.:

Service- Indirect steam heating limpet coil reactor

Steam Inlet Pressure- 3 bar g

Inlet size- 50 NB

Steam/ Condensate Flow- 380 Kg/hr

Pressure Drop of equipment- 0.5 bar g

Back pressure- 0.2 bar g

Selected Trap:

UKL Ball Float trap, Model- UFT 14 CI, DP- 4.5 Bar, Non IBR

End connection- SCR to BSP/ BSPT/ NPT

OrUFT 20 CS, DP-4.5 Bar, Non IBR End connection- F/E 150#

Size- 25 NB, 1 no. Qty

How Trap assembly looks:

CLOSED LOOP

OPEN LOOP

Selection on Trap selection:

Wherever for ease of maintenance, cleaning of trap always do prefer Flanged end connection trap so that trap can be remove within time & maintenance can be done immediately,

Now if in case very LP steam pressure application & prefers to install cast Iron then in such case choose screwed ends to BSP/ BSPT/ NPT,

In high pressure application above 10 Bar g & max do prefer Socket weld end so that chances of leakage will be very less because in sometime it may happens due to gasket wrong selection & gasket self life frequently leakage is occurs and then removal of trap time continues.

However in such case during welding procedure will require qualified IBR welders & whenever removal/ replacement of trap that time removal of cost & re-fitment cost is very high compare to screwed ends and Flanged end connections.
