What is the difference between PVC conduit, A conduit, and B conduit?

The differences between the two are as follows:

1. The material used for pipe A is better than that for pipe B, with a higher strength and a thicker thickness.

2. Tube A is more expensive than tube B.

3. Pipe A is usually used for drainage and pipe B for ventilation.

Advantages of PVC-U pipe:

1. It has good tensile and compressive strength, but its flexibility is not as good as other plastic pipes.

2. Low fluid resistance: PVC-U pipes have very smooth pipe walls and low resistance to fluid, with a roughness coefficient of only 0.009. Their water delivery capacity can be increased by 20% compared to cast iron pipes of the same pipe diameter and 40% compared to concrete pipes.

3. Excellent corrosion resistance and drug resistance: PVC-U pipes have excellent acid, alkali, and corrosion resistance, and are not affected by moisture and soil acidity and alkalinity. No anti-corrosion treatment is required during pipeline laying.

4. Good water tightness: PVC-U pipes are installed with good water tightness regardless of whether they are connected by adhesive or rubber rings.
