1. Thickness standard of pvc drainage pipe

1, different nominal inner diameter of pvc drainage pipe thickness standards are not the same, the general nominal inner diameter of 90 drainage pipe wall thickness is 3.0mm - 3.5mm.

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

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

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

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

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

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

Two, pvc drainage pipe characteristics

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

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

3, pvc drainage pipe of inorganic acid, alkali, salt corrosion resistance is excellent, more suitable for industrial sewage discharge and transportation.

4. The pipe friction coefficient of pvc drainage pipe is small, the water flow is smooth, it is not easy to plug, and its maintenance workload is less.

5, pvc drainage pipe material oxygen index is high, with good self-extinguishing.

6, pvc drainage pipe linear expansion coefficient is small, 0.07mm/℃, affected by temperature deformation is small, and thermal conductivity and elastic modulus is small, compared with cast iron drainage pipe freezing resistance is also quite good.

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

8. PVC drainage pipes also have good water tightness, because the installation of PVC-U pipes, whether adhesive or rubber ring joint, all have good water tightness.
