Trap selection help
Thread Content
The caliber is DN50 and the displacement is about 4000KG/H. Which one is better? Thank you.
Choose the caliber according to the flow, choose the caliber according to the flow, choose the caliber according to the flow, say the important things three times! ! ! Another problem is that when the material of cast steel is 350°C, PN25 can actually withstand 15 kilograms, and PN40 can withstand 24 kilograms, so your PN16 is absolutely unacceptable. If you want to know more, just message me.
1.2MPa+370°C~~With such a high degree of superheat, there is actually 4 tons of drainage~~~ Sir, are you sure your calculation is correct?
Many domestic trap manufacturers or construction teams will directly equip you with a trap that has the same diameter as the pipe. Often the problem lies here, because you don’t know the amount of condensate, and most of the selected traps will not work properly. For equipment trapping, the correct selection is more important. The caliber of the trap must be selected according to the amount of steam used. If the trap is selected too large, there will be a risk of air leakage. If the trap is selected too small, the condensate will not drain out, affecting the heat exchange of the equipment. I don’t know what you mean by saying that traffic volume has little to do with caliber.
I agree with your point of view. It is very common to select valves based on pipe diameter. What I mean is that the drain displacement is determined by the size of the drain valve seat. A large valve seat has a small pressure difference and a low displacement. ； The valve seat is small, the pressure difference is large, and the displacement is large.
It’s a bit convoluted. To put it simply, the displacement of the trap is not directly related to the diameter of the pipe, but to the drainage hole of the internal structure. The greater the inlet pressure, the smaller the drainage hole and the smaller the displacement.
1.2MPa+370°C Use superheated steam to heat equipment? So much water?
It is recommended that the trap be imported. The difference between imported and domestically produced items is not as big as usual.
Choose a bell-shaped float steam trap
