PVC-U S12.5 Pipes Industry knowledge

Introduction to PVC-U S12.5 pressure pipe: the ideal choice for high performance and reliability

In modern buildings, municipal engineering, agricultural irrigation and industrial systems, the reliability and durability of the pipeline system are directly related to the overall quality of the project. PVC-U (rigid polyvinyl chloride) S12.5 pressure pipe has become one of the preferred pipes in many projects due to its excellent physical and chemical properties.
Zhongjia PVC-U S12.5 pipe uses high-quality rigid polyvinyl chloride (PVC-U) as the main raw material, meets DIN standards, and has good pressure resistance, corrosion resistance and long service life. The nominal pressure rating of this series of pipes is PN8, which is suitable for medium-pressure water supply and drainage systems.
1. Excellent corrosion resistance
PVC-U material has extremely strong chemical stability and can effectively resist corrosion from chemical substances such as acids, alkalis, and salts. Therefore, it has a natural advantage in industrial drainage, chemical fluid transportation and other scenarios. Compared with metal pipes, PVC-U pipes are more durable in humid or corrosive environments and are not easy to rust or scale.
2. Good pressure bearing capacity
The S12.5 series indicates that the wall thickness of the pipe is moderate and has good strength performance. Under the PN8 nominal pressure condition, Zhongjia PVC-U S12.5 pipe can operate continuously and stably, and is suitable for medium pressure conditions such as water supply network, agricultural irrigation system, municipal pressure drainage, etc.
3. Lightweight and high strength, convenient construction
PVC-U S12.5 pipe has low density, and is lighter to transport and install than traditional metal pipes, which greatly reduces labor costs and construction difficulty. At the same time, the Plain End design is convenient for connection with other PVC accessories, flanges or sockets, which improves the efficiency of on-site installation.
4. Environmentally friendly and non-toxic, water quality is safe
Zhongjia brand uses PVC-U materials that meet environmental protection standards, does not contain harmful plasticizers, and meets the safety requirements of drinking water pipes. It is widely used in domestic water supply systems and drinking water transportation projects to ensure the safety of terminal water quality.
5. High cost performance
Compared with PE or stainless steel pipes, PVC-U pipes have lower material costs, but their service life can reach more than 30 years, with low comprehensive maintenance costs and significant economic benefits.
Product application scenarios
Zhongjia PVC-U S12.5 pressure pipe is widely used in the following fields:
Municipal water supply system: as the main pipeline of cities or towns, suitable for medium pressure transportation;
Building water supply and drainage system: suitable for indoor and outdoor pipe network layout of high-rise or medium-rise buildings;
Agricultural irrigation project: can be used for main line or branch line of sprinkler and drip irrigation system;
Industrial transmission pipeline network: suitable for conveying chemical liquids, cooling water, process water and other fluids;
Water treatment and environmental protection projects: used in sewage treatment plants or reclaimed water reuse systems.

Zhongjia provides a variety of specifications from DN80 to DN300, covering most municipal and industrial needs. Among them:
DN80, DN100: commonly used in small water supply systems or branch pipe layout;
DN150, DN200: suitable for medium-sized engineering main pipes;
DN250, DN300: used in large water plants, municipal main lines and other projects.
All specifications are flat-end structures, which are convenient for matching rubber rings, sockets or flange connectors.
Zhongjia brand PVC-U S12.5 pressure pipe has become the designated pipe material for municipal engineering and construction projects in many countries due to its excellent physical properties, good chemical resistance, stable pressure resistance and high economy. Whether it is a new project or a pipe network renovation project, Zhongjia PVC-U S12.5 pipe can provide a reliable, safe and economical water delivery solution.
