Underground PVC pipe is made of polyvinyl chloride (PVC), a synthetic resin, which is extruded after adding stabilizers, lubricants, and plasticizers. PVC pipes have high surface hardness and tensile strength, good anti-aging performance, and a service life of more than 50 years under normal use conditions.
Differences between underground PVC pipe and ground PVC pipe
1. Application: Underground PVC pipe is mainly used for underground facilities such as water supply and drainage, such as indoor water supply and reclaimed water systems in civil and industrial buildings, buried water supply systems in residential areas and factory areas, urban water supply pipeline systems, water treatment pipeline systems in water treatment plants, and marine aquaculture, garden irrigation, and other projects. In contrast, ground PVC pipes are mainly used for building drainage, domestic sewage drainage, etc.
2. Specifications: There are more specifications and models of underground PVC water supply pipes to meet the requirements of various projects; while there are relatively fewer specifications and models of ground PVC drainage pipes because the drainage system itself does not require too many specifications. Even with the same model (outer diameter), the wall thickness of water supply pipes and drainage pipes is often different.
3. Pressure requirements: PVC Pipes for water used underground have clear pressure requirements, while PVC drainage pipes used on the ground usually do not need to consider pressure issues.
Application areas
1. Municipal drainage projects: PVC pipes are used for rainwater and sewage discharge in urban roads, squares, parks, and other places, which is essential for maintaining the cleanliness and hygiene of the urban environment.
2. Industrial drainage: Suitable for drainage in factories, workshops, warehouses, and other places, and can discharge industrial wastewater and production sewage, which is of great significance for protecting the environment and workers’ health.
3. Building drainage: Used inside buildings, such as basements, underground garages, and other places to ensure the normal operation of the drainage system inside the building.
4. Farmland drainage: Improve the drainage efficiency of farmland, protect the growth of crops, and promote the development of agricultural production.
5. Water conservancy projects: In water conservancy facilities such as dams and canals, PVC pipes are used in drainage systems to ensure the normal operation of water conservancy projects.
6. Road drainage: Used for drainage of roads such as highways and railways to prevent water accumulation on the road and improve traffic safety.
7. Mine drainage: Used in the drainage system of mines to discharge groundwater and mine water from mines to ensure the safety of mine operations.
Characteristics
Underground PVC pipe is relatively resistant to compression and tension. This kind of pipe is mainly used for water supply and drainage. Its pipe wall is very smooth, so its resistance to fluid is relatively small. It has certain corrosion resistance and pressure resistance. During construction, no anti-corrosion treatment is required. It has very good water tightness. However, its thermal stability is relatively poor and it is easy to become brittle.
