Rigid polyvinyl chloride (PVC-U) reinforced pipe knowledge
product manualPVC-U reinforced pipe is a new type of PVC-U pipe that adopts advanced foreign formula, is continuously extruded by unique process equipment, has a smooth inner wall, and has vertical reinforcing ribs on the outer wall. It is mainly used for buried sewage and drainage systems. Because the outer wall adopts the principle of I-shaped steel, PVC-U reinforced pipes have unique performance advantages, and gradually replaced traditional cement pipes and other PVC-U pipes in the sewage series, becoming the most advanced buried drainage in the world. 3. Sewage pipes.
Features
▼ New materials, the outer wall structure designed by the principles of physical mechanics, reasonable structure, high strength, and good physical and mechanical properties;
▼ Smooth inner wall, small fluid resistance, large flow volume, not easy to scale, under the same flow conditions, the pipe diameter can be reduced and the amount of civil engineering can be reduced;
▼ Corrosion resistance, reliable connection, good leakage resistance, good environmental protection and safety;
▼ Good anti-uniformity settlement effect;
▼ Light weight, easy handling and installation, no need for concrete foundation for the pipe, and the construction speed is fast;
▼ Long service life, normal service life can reach more than 50 years;
▼ Side connection method: adopt rubber ring connection method for connection.
Product application areas
Widely used in municipal sewage, drainage pipeline systems and sewage and drainage pipelines outside buildings; system engineering construction, agricultural irrigation, power communication, cable protection and industrial sewage and other fields.
