PVC Drilling Pipe

   PVC well drilling pipe is a type of PVC drainage pipe used in mines, mainly refer to pipes made of polyvinyl chloride (PVC) material used for well drilling. PVC material has been widely used in the field of well drilling due to its lightweight, corrosion resistance, and low cost. The main functions of PVC water pipe for well drilling include carrying groundwater, preventing water pollution, and maintaining the stability of the well structure.

The usage method of PVC drilling pipe
When using PVC drilling pipes, it is usually necessary to consider factors such as the depth of the well, geological conditions, and the specifications of the PVC pipe. During the construction process, first expand the wellbore, then use a drilling rig for drilling, while flushing and timely discharging water, sand, and slag. When installing well pipes, it is necessary to choose appropriate well pipe materials and connection methods to ensure installation quality and wellbore integrity.

The advantages of PVC drilling pipes
1. Lightweight: The density of PVC pipe ranges from 1.35 to 1.46, slightly higher than the buoyancy of mud, making it easier to lower pipes and reducing labor intensity.
2. Strong corrosion resistance: PVC is a stable polymer that hardly reacts with chemicals such as acids, alkalis, and salts. It has good durability and a service life of at least 50 years.
3. Long single length: The PVC wellbore pipe is generally 6 meters in length, reducing the number of joints and saving time and material for running the pipe.
4. Good water quality: Sanitary grade PVC water supply pipe is hygienic, non-toxic, and do not breed bacteria, ensuring water quality.
5. Low cost: Compared with steel HDPE pipe of the same specifications, PVC wellbore pipes have a lower price and significantly lower transportation costs.
6. Smooth inner wall: Good hydraulic conditions, low friction coefficient, and low energy consumption.
7. Good flexibility and high impact strength: it has good compressive performance and is not easy to break.
8. Wear resistance: suitable for various water quality wells, especially in recent years, the widespread application of submersible electric pumps. The induced current generated in water accelerates the corrosion of traditional well pipes, while plastic well pipes are not affected by this.
