The key advantages of prestressed reinforced concrete pipes lie in cost control, pressure resistance, and durability, as follows: There is a significant cost advantage – compared to metal pipes, around 70% less steel is required, which reduces the construction cost by approximately 60%. This makes them much more affordable than competing products such as steel pipes and fiberglass pipes, making them an excellent choice for projects with limited budgets. Excellent mechanical properties: By applying compressive stress to the concrete through a prestressing process, its crack resistance and water impermeability are significantly improved compared to ordinary reinforced concrete pipes; it can withstand higher internal radial pressures, and large-diameter pipes are suitable for applications involving high-pressure water transmission ； The concrete strength of the pipe body can exceed 50 Mpa; it has high structural stiffness and good resistance to external pressure, making it suitable for burial. Advantages in corrosion resistance and lifespan: It boasts significantly better corrosion resistance than metal pipes, and the pipe wall can be equipped with a PE lining to further enhance its anti-corrosion properties. Its designed service life is over 50 years, ensuring good stability over long-term use. Suitable for large-diameter engineering projects: The inner diameter range spans from 10 centimeters to several meters. Prestressed concrete pipe (PCCP) is the dominant piping material for high-pressure, large-diameter long-distance water transmission projects today, and it can meet the needs of large-scale projects such as urban water supply systems and water diversion projects.
