Home decoration water pipe selection, the thicker the PPR water pipe is, the better? Is the thin-walled water pipe not easy to use?

Today I looked at such a question in Zhihu. Whether the water pipe is thick or thin is good. Everyone has their own opinions and cannot compete. Let's hear what these friends say. I ca n’t say, what do you think? This is a PPR water pipe, so let ’s leave it aside, it ’s not a thing. The answer also said that wall thickness has nothing to do with pressure and temperature resistance is nonsense. The wall thickness of the PPR water pipe is directly related to the pressure bearing capacity of the water pipe, and the pressure bearing is related to the temperature. The wall thickness of 25-size water pipes commonly used in current domestic PPR water pipes is generally two specifications of 3.5mm and 4.2mm. This corresponds to the two tube series S3.2 and S2.5. The answer said that using PPR water pipes with thin wall thickness is generally no problem, so the thicker the PPR water pipe, the better, which is obviously wrong. If water pipes with a thinner wall thickness are generally okay, then it can be said that water pipes with a thicker wall thickness are even more problem-free. When the wall thickness is thicker, when it encounters some extreme conditions, it is obviously that the pressure bearing capacity is better and it will be more secure. Under normal circumstances, the service life will definitely be longer. Ask the market for two specifications. I know the price of the water pipe. Others say that the thicker the wall of the water pipe will affect the water flow, it is actually not the same. The wall thickness and pipe diameter specifications of the water pipe are designed through calculation. Under normal circumstances, they can meet the daily water demand. It is true that the water flow of a small inner pipe will be smaller, but the impact will be minimal and will not affect the water experience. What causes the water experience is often caused by poor welding, which causes welding plugs, and the inner diameter of the water pipe at the welding site is severely reduced. From a practical point of view, the 3.5mm and 4.2mm water pipes are both 25mm in diameter. Under this specification, as long as the welding is good, the flow can fully ensure the water experience. There is a commonly used pipe diameter of 20mm smaller than this. The specifications of the water pipe, the corresponding wall thickness of the same pipe series are 2.8mm and 3.4mm, So you can see that it is actually the diameter of the water pipe that affects the flow rate. The difference in wall thickness of water pipes of the same pipe diameter specification will not exceed 1mm, but the effect on the pressure bearing capacity is indeed significant. Therefore, the actual situation is that you want to use water a bit more coolly, and choose a larger pipe diameter instead of a thinner wall thickness. Why would anyone say that the wall thickness is thin? This is of course related to cost.
