How to judge the quality of nylon tube?

PP (Poly Propylene) tubes are divided into several categories:

1, PP-B (embedded segment co-polypropylene) due to the use of solute technology in the construction, so also commonly known as thermal solubility pipe. Because of its non-toxic, light, pressure, corrosion resistance, is becoming a promotionof material, but the current decoration project is relatively few, in general, this material is not only suitable for cold water pipes, but also suitable for hot water pipes, and even pure drinking water pipes.

2, PP-C (modified co-polypropylene) tube, performance is basically the same.

2, PP-R (irregular co-polypropylene) tube, performance is basically the same.

PP-C(B) is basically similar to the physical characteristics of PP-R, the application range is basically the same, and can be used in engineering. The main difference is that PP-C(B) material resistance to low temperature brittleness is better than PP-R, PP-R material high temperature resistance is better than PP-C(B). In practical application, PP-C (B) tubeist is preferred when the liquid medium temperature is 5 degrees C, PP-R tube is preferred when the liquid medium temperature is 65 degrees C, and PP-C (B) and PP-R are basically the same when the liquid medium temperature is between 5 degrees C and 65 degrees C.

Aluminium PP-R:

As the name implies, the PP-R tube with aluminum layer in the middle. The difference with PAP should be mainly the plastic material used in the inner and outer layers, one is PP-R (polypropylene), the other is polyethylene.

PE-RT:

Heat-resistant polyethylene, as if in the floor heating used more, but there is information that health performance is very good

PVC-U or U-PVC:

Hard PVC. Food safety performance is higher than PVC
