Is it necessary to install anti-backflow plates in U-tube heat exchangers? Please reply, guys. Thank you

At 3.1 MPa, with a steam flow rate of 1.2 m/s and a steam temperature of 280°C, is it necessary to design an anti-erosion plate? Thank you
Okay, thank you. One more question: if the steam flow rate is only 0.4 m/s, is it still necessary to add it? After adding it, part of it cannot be routed through pipes.
GB151 requires the installation of anti-impact plates; per clause 6.8.1.1,c, this applies in the presence of corrosive gases, steam, and gas-liquid mixtures
There are definitely experts providing support; thank you for sharing your knowledge
According to relevant safety regulations, it’s better to do so
The anti-erosion plate is designed to protect the heat exchange tubes; it has nothing to do with U-tubes. GB151 specifies requirements regarding whether an anti-erosion plate should be used, and you can make a judgment based on your parameters.
