Thickness and Advantages of PVC Drainage Pipe

Standard for thickness of pvc drainage pipe

1. The Thickness standards for PVC drainage pipes with different nominal inner diameters are different. Generally, the drainage pipes with a nominal inner diameter of 90 have a small wall thickness of 3.0mm-3.5mm.

2. The wall thickness of drain pipe with nominal inner diameter of 110 is 3.2 mm - 3.8 mm.

3. The wall thickness of drain pipe with nominal inner diameter of 125 is 3.2mm - 3.8mm.

4. The wall thickness of drain pipe with nominal inner diameter of 160 is 4.0-4.6 mm.

5. The wall thickness of drain pipe with nominal inner diameter of 200 is 4.9 mm - 5.6 mm.

6. The wall thickness of drain pipe with nominal inner diameter of 250 is 6.2mm - 7.0mm.

7. The wall thickness of drain pipe with nominal inner diameter of 315 is 7.8mm - 8.6mm.

Features of PVC drainage pipe

1. The surface hardness and tensile strength of pvc drainage pipe are excellent, so we say its pipeline safety system is very high.

2. The aging resistance of PVC drainage pipe is also very good. If it is used normally, its service life can reach more than 50 years.

3. The pipes of pvc drainage pipes have excellent corrosion resistance to inorganic acids, alkalis and salts, and are relatively suitable for industrial sewage discharge and transportation.

4. PVC drainage pipe has small friction coefficient, smooth water flow, and is not easy to block, and its maintenance workload is small. 

5. The material of PVC drainage pipe has high oxygen index and good self-extinguishing property.

6. The linear expansion coefficient of pvc drainage pipe is small, 0.07mm/℃, the deformation affected by temperature is small, and the thermal conductivity and elastic modulus are small. Compared with cast iron drainage pipe, the frost resistance performance is also quite good.

7. The pipes and pipe fittings of PVC drainage pipes can be connected by bonding, and its construction method is simple, the operation is also quite square, and the natural installation efficiency will be very high.

8. PVC drainage pipes also have good water tightness, because in the installation of PVC-U pipes, whether they are bonded or connected by rubber rings, they all have good water tightness.
