What is PVC-U casing pipe?

PVC-U casing pipe is a kind of pipe made of Unplasticized Polyvinyl Chloride (PVC-U), which is mainly used in groundwater extraction, geothermal Wells and environmental monitoring Wells. Due to its excellent physical and chemical properties, PVC-U casing pipe has been widely used in many industries.

Characteristics of PVC-U casing pipe

1. Corrosion resistance

PVC-U material has excellent chemical corrosion resistance, will not be affected by acid, alkali, salt and other corrosive substances in groundwater. Therefore, PVC-U wall pipe can maintain stable performance for a long time and will not affect the service life due to corrosion. 

2. Light weight

Compared to traditional metal pipes, PVC-U casing pipe are lighter and easier to transport and install. This not only reduces the transportation cost, but also reduces the labor intensity in the construction process and improves the work efficiency.

3. High intensity

Despite its light weight, PVC-U casing pipe is still very strong and can withstand high pressure and mechanical stress. This enables it to work stably in the harsh underground environment, ensuring the safety and reliability of the project.

4. Cost effectiveness

With relatively low production and maintenance costs, PVC-U casing pipe is a cost-effective option. Not only is it less expensive to purchase and install, but maintenance costs are also significantly reduced due to its corrosion resistance and high strength.

5. Non-toxic

PVC-U material is non-toxic and harmless, will not cause pollution to water quality, suitable for drinking water extraction. This feature makes PVC-U wall pipes particularly important in applications where water safety is required.

6. Smooth the inner wall

The inner wall of the PVC-U casing pipe is very smooth, which can reduce the friction resistance of the water flow, thereby increasing the water speed and saving energy. The smooth inner wall also reduces the adhesion of dirt and sediment, further reducing the difficulty of maintenance.

PVC-U casing pipe application field

1. Groundwater extraction

PVC-U casing pipe is widely used in agricultural irrigation, industrial water and domestic water underground Wells to ensure water quality safety and stable water supply. 

2. Geothermal Wells

With the rise of geothermal energy development, PVC-U casing pipe is more and more used in geothermal Wells. Its high temperature and corrosion resistance make it an excellent choice for geothermal energy development.

3. Environmental monitoring well

In the field of environmental protection, PVC-U casing pipe is used for monitoring and pollution prevention of groundwater environment, helping environmental protection departments to grasp the status of groundwater in time and take corresponding treatment measures.

4. Mine drainage

In mine drainage and mine waterproofing engineering, PVC-U casing pipe also plays an important role. Its high strength and corrosion resistance ensure the stable operation of mine drainage system.

How to buy PVC-U casing pipe?

1. Pipe specifications

According to the factors such as well depth, well diameter and water quality, the appropriate PVC-U casing pipe specifications are selected to ensure that they can meet the actual needs of use.

2. Quality certification

Choose certified PVC-U casing pipe products to ensure that they meet industry standards and use requirements. Quality certification is the guarantee of product performance and safety, which can not be ignored.

3. Brand reputation

Choose reputable brands to ensure product quality and after-sales service. Well-known brands usually have better production processes and quality control systems, which can provide more reliable products.

PVC-U casing pipe is widely used in groundwater extraction, geothermal Wells, environmental monitoring Wells and mine drainage because of its corrosion resistance, light weight, high strength, high cost effectiveness, non-toxicity and smooth inner wall. When purchasing PVC-U wall pipe, the appropriate specifications should be selected according to the actual needs, and pay attention to the quality and brand reputation of the product. Understanding this knowledge will help you better apply and maintain PVC-U wall pipe to ensure its effect and life in actual use.
