The shortage of water resources is a global problem. And the per capita water resources in China is only 1/4 of the world average. As an important water drawing project for exploitation and utilization of groundwater resources water wells plays an important role in the development and utilization of groundwater resources,the development of agricultural irrigation and human and livestock water using in our country.The traditional pipes used in the construction of water wells are mainly cast iron pipes, steel pipes, and cement pipes. Due to the serious corrosion problems of these pipes, they not only affect the service life of the water well, but also produce many undesirable consequences, such as: sand gushing from the water well, the ground subsidence, water pollution and stratum collapse, etc. Which cause very alarming losses every year.
The plastic well casing pipes are widely used in abroad water well projects , especially in developed countries because of its great characteristics of light weight, strong corrosion resistance, good durability, and low cost. There are more than 80% of the counties use plastic well pipes. In recent years, as people’s awareness of environmental protection has increased, our country has begun to vigorously promote the application of plastic pipes for water wells.
The PVC-U water well piping system is a new type of plastic piping product developed by Hesu Pipe Industry in the course of decades of production practice, based on the characteristics of PVC-U series water supply pipeline and market demand. The PVC-U water well piping system is composed of a special PVC-U well pipe and a PVC-U water filter pipe, and the connection adopts a high-strength threaded connection.
Hesu Pipe Industry can not only process PVC-U water filter pipes, but also produce rainwater collection pipes, anti-seepage pipes, drip irrigation pipes, etc. according to your needs. The specification of the PVC slotted pipe is dn20mm-dn800mm. They can be widely used in many fields such as airports, railways, highways, sports fields, parks and greenbelts, retaining walls, basements, tunnels, slope protection drainage; mine tail dams, thermal power plant ash dams, waste landfill drainage systems; rainwater collection and recycling Utilization; agricultural irrigation; mud drainage from water plants etc.
Characteristics Of PVC-U Well Casing Pipe:
Light weight, convenient transportation and installation.
Strong corrosion resistance and good durability.
The single length is long, and the well pipe joints are few.
Sanitary PVC-U pipe is hygienic, non-toxic, does not breed bacteria, and does not pollute water.
The PVC well casing pipe is cheap and the cost of the completed well is low. Compared with the steel well pipe of the same specification, the price of PVC-U well pipe is 1/3 lower. In addition, the finished pipe is light in weight, the transportation cost can be greatly reduced: the well pipe is easy to install and transport, therefore the manpower and material resources in the process of completing the well can be greatly saved.
The inner wall is smooth and the hydraulic conditions are good. It can effectively ensure the long-term and unblocking of the pipeline. It will also be easier to rinse off those that need back-washing. The friction coefficient is only 0.0008-0.009, and the energy consumption is small.
Good flexibility, high impact resistance.
Durable: It has excellent abrasion resistance and can greatly reduce the abrasion of the water filter pipe’s water gap caused by the inlet water.
