3 S t e a m T r a p Selection of If steam gives heat to an object an loses quantity of heat, it will conense an will return to warm water. This conensation water is calle conensate. In steam transportation piping an the apparatus which uses steam, this conensate becomes obstructive existence an causes water hammer or ecreases in thermal efficiency. In such steam systems, steam trap only ischarges the unncessary conensate. s Steam transport pipe, Heat exchanger, Air-heater, Process heater Heat exchanger, Air-heater, Process heater Steam transport pipe, Raiator for heating Thermoynamics type Mechanical type Thermostatic type Types Actuates by the thermoynamic characteristics of steam an conensate.

4 S t e a m T r a p Note for Selecting There are various kins of steam trap classifie by operation, ischarge capacity, etc. In orer to obtain the full benefit from the traps, selecting proper trap size an pressure is essential. The followings are consierations to select the proper traps. 1: Service point Each service point has each requirements for steam traps. Please consier the following points to select the proper traps. Steam piping / Heaer Not affecte by outsie temperature Air ischarge at the starting system Small steam loss At the en of piping Discharges mass volume at the startingcontinuous blow Air ischarge at the starting system Equipment / process Operates uner fluctuation of conensate volume High back pressure operation Air ischarge at the starting system No accumulation of conensate at the time of failure 2: Discharge capacity TS-78, TF TSD-42, TD-10NA, TSD-77F TF A 1800 Discharge capasity /h TF A TF-2 15 TS-78 Discharge capasity /h TSD-77F TD-10NA 15- TSD Differential pressure MPa Differential pressure MPa 3: Safety factor The graph for ischarge capacity is showing the capacity of ischarging continuously. The trap requires the allowance to cover the amount of conensate fluctuation. Such allowance is the safety factor of steam trap. For instance, safety factor 3 means that the steam trap ischarging 900 kg/h is require to ischarge conensation amount 300 kg/h. Type Moel Safety factor TSD-42 Thermoynamics TD-10NA 4 or more TSD-77F Mechanical TF-2 3 or more Thermostatics TS-7 3 or more 4: Differential pressure Because of operation, allowable back pressure is less than 50% of inlet pressure for thermoynamics type. On thermostatic an float type, back pressure has no averse effect on operation, but as back pressure approaches to inlet pressure, ischarge becomes less since ifferential pressure will be low.

5 S t e a m T r a p of Thermoynamics Type TD-10NA 1: Bi-metal ring If the inlet pressure rise up too fast in the starting time, ue to high-spee air, a trap will be close by the same principle as steam, an anair-biningwill occur. This is cancelle with the bi-metal ring which starts to expan only by the temperature. Such function enables prompt ischarge of col water an air off at starting, an also results in efficient start-up of steam apparatus. 2: Insulation cover When installe uner col ambient conitions, steam in chamber conensates faster than usual. This coul make life of isc an valve seat shortene, ue to too much wear by frequent on-off. To avoi this, the insulation cover prolongs conensation time of steam in chamber, an the frequent on-off operation of a isc is suppresse, an long urability is maintaine. In aition, stable operation is obtaine espite a rop in outsie temperature. 3: Avantages Small, lightweight Installable in any irection Applicable on super heate steam

For example, if you nee a steam trap with a capacity of 100 kg/h, the trap with a capacity of 400 to 500 kg/h shoul be selecte for maximum efficiency. The back pressure (outlet pressure) shoul be consiere in selecting ischarge capacity. This is because ischarge capacity of a trap epens on the operating ifferential pressure (the ifference between the inlet an the outlet pressures). For example, to fin the ischarge capacity obtaine by the inlet pressure is 1.0 MPa an the outlet pressure is 0.2 MPa, trace up from the point of the operating ifferential pressure of 0.8 MPa in the above chart.

STOP: Flui oes not flow into the trap an out of the bypass because the inlet, the outlet, an the bypass are close, an the strainer can be cleane an the bellows can be inspecte. 2. BY-PASS: Flui flows through the bypass irectly to the outlet. Select this position when blowing the piping uring plumbing or ischarging a large quantity of conensate before starting operation. Since flui oes not flow to the trap, the strainer can be cleane an the bellows can be inspecte. 3. TRAP: In this position, the steam trap performs regular trap operation, an conensate flows from the inlet to the outlet through the trap. It oes not flow out of the bypass. 4. TEST: In this position, conensate is ischarge from the inlet to the outlet for testing through the trap, an the operation of the trap can be checke. This check can be carrie out with the outlet close an without being affecte by back pressure. Flui oes not flow out of the bypass. Precaution for Installation Piping Example 1. Carefully blow the piping before connecting the steam trap. 2. Connect the steam trap to the piping accoring to its arrow inicating the irection of flow. 3. Slope the piping an place the prouct at as a low position as possible in orer to make conensate flow into the prouct by its own weight. 4. Do not insulate the piping inlet an the steam trap. 5. To install the prouct in a main steam pipe, provie a rip leg at the inlet sie of the prouct. 6. Secure enough space for switching operation of the cock an maintenance (such as cleaning the strainer an inspection of the bellows). 7. If ischarge capacity is not enough, install more than one trap. In this case, connect the traps to the piping so that their inlets are in the same level. 8. Do not install the steam trap in a place where ambient temperature is higher than the conensate to be ischarge. En of pipe Main piping Horizontal piping ateral piping Vertical piping Drip leg
