What is the difference between it and ordinary concrete pipes

The core difference lies in the”prestressing”process.High-strength steel wires are tensioned before the concrete is cast,placing the pipe body in a state of compression before it even bears internal pressure.This significantly enhances its crack resistance,impermeability,and load-bearing capacity,enabling its use in large-diameter,high-pressure water transmission mains—a capability ordinary concrete pipes lack.

What are its primary engineering applications

It is specifically designed for large-diameter, high-pressure water transmission scenarios. It is one of the preferred pipe materials for urban water supply trunk lines, large-scale water diversion projects, power plant circulating water pipelines, and high-pressure agricultural irrigation systems. It is generally not used for gravity-flow drainage or low-pressure branch lines.

For the main water supply network project in our city's new district, we fully adopted your company's PCCP pipes. The pipes demonstrated excellent pressure-bearing capacity and impermeability, particularly in withstanding water hammer pressure and complex geological conditions, with no abnormalities observed. Three years of operational monitoring data show full compliance with standards, providing a solid guarantee for the city's safe water supply.

As a participating construction unit for the supporting project of the South-to-North Water Diversion, we placed great emphasis on the material's durability and full lifecycle cost. The prestressed concrete pipes provided by your company not only fully met the design requirement of 1.0 MPa working pressure, but their optimized structural design and high-quality protective coating also give us full confidence in the pipeline's stable operation over the next fifty years.

During the construction of a major water diversion project overseas, your company's products stood out for their outstanding quality. The pipes exhibited excellent joint sealing and high installation efficiency, significantly shortening the construction period. Even the harsh local soil corrosion environment had no impact on the pipeline's performance, earning unanimous praise from the project owner and supervision team.

Frequently Asked Questions

What pressure rating can it achieve?

It has a strong pressure-bearing capacity. Common working pressure ratings range from 0.4 MPa to 1.2 MPa, or even higher, depending on pipe diameter, reinforcement design, and standards. During selection, the pressure class must be determined based on the project’s design working pressure, soil cover depth, and surface loads.

It primarily uses flexible bell-and-spigot joints with rubber gaskets. During installation, a specially designed rubber gasket is placed between the spigot and bell ends; the thrust force during jointing compresses it, creating an elastic seal. When installed according to specifications and with a properly prepared foundation, the seal is highly reliable, allowing for minor deflection and movement without leakage.

Thanks to the high-strength steel wires being protected by concrete, it offers excellent durability with a typical design service life of over 50 years. Although the initial unit cost may be higher than some other pipe materials, its long lifespan, minimal maintenance requirements, and stable long-term hydraulic performance result in very high overall cost-effectiveness throughout the lifecycle of large water transmission projects.
