Both polypropylene and steel-lined PTFE can prevent corrosion. Which one should be used?

Both polypropylene and steel-lined PTFE can prevent corrosion, so why use steel-lined PTFE pipes? Will it be possible to use polypropylene directly?
Temperature, pressure, permeability, many issues need to be considered. Of course there is also the issue of cost.
Plastic pipes may not be strong enough and difficult to connect.
There is also the issue of solvent resistance that must be considered
There are many issues related to the temperature, pressure, permeability of the medium and the properties of the medium. . . . .
It is recommended that steel-lined glass pipes are very easy to use and can withstand temperature, pressure and basic materials, haha
If the temperature of polypropylene changes greatly, the pipe will be easily deformed, and the flange will be torn apart. Especially in summer when the temperature difference is large
The maximum operating pressure and temperature of polypropylene pipes are not as good as those of steel-lined PTFE pipes. If your requirements can be met by both, of course choose the lower-priced former.
The person above is right. It is good to choose PP when the occasion is not demanding. However, when the pressure and temperature conditions are harsh, it is better to use steel lined with PTFE. After all, there is a layer of steel outside, which will provide psychological stability.
How are the materials of general steel-lined PTFE pipes calculated? Especially when it comes to pipeline professional statistics? After all, this kind of pipe must be flanged, in two-meter sections. What should I do?
Surface area, and seam. For example, a circle with a diameter of 1 meter consumes a plate of 1 meter long and one meter wide. The scrapped part is yours. If there is a vent pipe or the like connected to the circle, it will be calculated separately, because the cost of welding a seam with an arc length of 20 cm is about 100 yuan.
