In what situations are plate heat exchangers suitable?

What types of operating conditions are suitable for plate heat exchangers? http://bbs.hcbbs.com/thread-1669445-1-1.html In this post, regarding the issue mentioned by Fred, there are several sets of this device in the setup, so I wanted to ask.
Previously in chlor-alkali plants, plate heat exchangers were basically used everywhere
In gas-to-gas or gas-to-liquid heat exchange, plate exchangers have many advantages over tube exchangers.
Low pressure difference, not too high temperature, clean medium
If a tubular type doesn’t fit, a plate-type is usually used – it’s more compact!
Indeed, it’s mainly these 3 points. It is generally believed that the pressure should not exceed 2.5 MPa and the temperature should not exceed 260°C; otherwise, the seal ring is prone to leakage.
