Could you please tell me about U-shaped bends in pipes?
Thread Content
Let me ask you about U-shaped bends in pipes: 1. What adverse effects will U-shaped bends have on the system when parking or driving? 2. For liquid media, the U-shaped bend will retain liquid. What will happen to gas media?
This is my personal experience, I don’t know if it is correct or not, please actively participate. 1. U-shaped bend, a clean pipe must be installed at the lowest point when parking.: If the liquid is drained, it must be drained through the drain pipe. If it is gas (if liquid is produced due to condensation), it must also be drained through the drain pipe, and it must be drained regularly. Otherwise, once the liquid is filled with liquid, a liquid seal will be formed and the pressure will be easily suppressed. 2. When going up a U-shaped bend, a vent pipe must be installed at the highest point when driving.: Open the vent until there is liquid overflowing without bubbles. If it is not exhausted, the gas in the pipeline will not be completely discharged, and it is easy to form air blockage.
Why do we need to add a "U" bend on the pipe? Is it steam or condenser liquid? “If the U"-shaped bend lies flat, it should have little impact on production.
Reply 6# wdh2010 The flat U-shaped bend is mainly used to relieve pipe stress.
The U-shaped bend on the pipe acts as an expansion joint. As for the location of the U-shaped pipe, the setting of the drain and vent pipe, etc., it is not a problem with the U-shaped pipe. Even if there is no U-shaped pipe, the settings that should be set must also be set. That * Tao system thing. Besides, this kind of thing should not be installed on the U-shaped pipe.
personal opinion: The top of the U-shaped bend is usually drained and the liquid below is usually used to prevent the backflow of gas and is usually sealed with liquid.
Agree with the point above! study * Got it
The U-shaped elbow acts as an expansion joint, mainly to relieve stress.
