Which type of pipe is less likely to develop scale or deposits that could cause blockages?
This is likely related more to the materials used; impurities in these materials tend to cause scaling, and changing the pipes does not provide a fundamental solution to this issue
It is closely related to the properties of the material, flow rate, temperature, and pipe structure, but has little to do with the pipe material

;P The most important thing is that the inner wall of your pipeline must be smooth. I remember someone mentioning before that those lined with PTFE are better than those made of metal
It should be as the people upstairs said – it is mainly influenced by factors such as the temperature and flow rate of the material. As for the pipe material itself, the inner wall of a PTFE-lined pipe is as smooth as that of a stainless steel pipe, but it possesses excellent corrosion resistance; it does not develop red rust, nor does it suffer from rusting or scaling due to the combination of metal ions such as iron with oxygen atoms in the air or liquids. It can reduce the scaling and deposition that result from this. I’d appreciate it if experts could share their opinions on this.
The problem cannot be solved by the material itself. Smooth the inner surface of the pipes, use elbows with large radii, create a gradient along the pipeline, adjust the pipe diameter, add heat tracing, and so on
The key is to consider the properties of the material; as for the pipes, their inner walls need to be smooth, and there should be as few bends as possible.
The surface roughness of metals is proportional to the scaling rate; the inner wall roughness of ordinary stainless steel pipes is 64RMS, while that of carbon steel pipes is 125RMS. In a refining plant in Gansu, scaling occurred on the interconnecting pipes made of stainless steel, which increased the inner wall roughness to 4RMS (mirror finish). During the major repair, removal of the component revealed that scaling was minimal, and cleaning it with ordinary pressurized water left it as bright as new
