PVC pipes can be used as well pipes. Compared with traditional pipes, pvc well wall pipes have the following characteristics:
1. Light weight and easy installation.
2. Strong corrosion resistance and good durability.
3. The single length is large, and the well pipe joints are few.
4. Good water quality. Sanitary PVC-U pipe is hygienic, non-toxic, does not breed bacteria, and does not pollute water quality.
5. The inner wall is smooth and the hydraulic conditions are good. The friction coefficient is only 00008, and the energy consumption is small.
6. Good flexibility and high impact resistance.
PVC pipe has low cost, light weight, good generalized physical and mechanical properties, low lubrication resistance of the pipe wall, no corrosion and scaling, long service life (50 years), fast well completion speed, no water pollution, no harmful and toxic substances dissolving and separating, etc. feature. In areas such as water wells, shallow geothermal energy development, etc., the intention of "replacement of steel with plastic" can be achieved.
PVC ( PolyVinylChloride polyvinyl chloride) generally has 7 levels (SG1-SG7) according to the hardness and performance of the material, and the density is about 1.4 g/cm³. Generally soft products below SG4 need to add a large amount of plasticizer during molding, mainly used to make artificial leather, wire and cable insulation layer, seals, etc.
