As production technology advances, more and more Zhengzhou concrete pipe manufacturers are wrapping their pipes in a thick protective layer to ensure safety. Don't underestimate this protective layer—it significantly improves the load-bearing, compressive, and fire-resistant properties of plain-end concrete pipes. How does this layer of protection achieve so much? Below, Zhengzhou Yuantong Concrete Pipe Factory will introduce it for you:

Ensure that concrete and steel reinforcement work together to ensure the structural load-bearing performance.

The collaborative effort of concrete and steel is fundamental to ensuring the load-bearing capacity and structural performance of components. Concrete is a brittle material with good compressive strength, while steel is a ductile material with excellent tensile strength. The combination of these two materials forms various structural forms of buildings or structures that possess compressive, bending, shear, and torsional resistance properties.

The joint work of concrete and steel reinforcement relies on sufficient bond strength between them, hence the smaller dimension of the concrete cover should not be less than the diameter of one reinforcing steel bar.

(2) Protecting plain-end concrete pipes from corrosion to ensure structural durability

Many factors can affect the structural durability of flat-end cement pipes and lead to structural damage, such as chloride ion corrosion, freeze-thaw damage, concrete impermeability, concrete carbonation, and aggregate reactions.Rust on flat-end concrete pipes expands in volume upon corrosion, causing the concrete protective layer to crack. Moisture or water seepage accelerates and intensifies the rusting of the flat-end concrete pipes, leading to their premature deterioration and contributing to building damage. Ensuring the protective layer thickness is within the design and specification limits can significantly protect the flat-end concrete pipes from rust, delaying the carbonation depth reaching the surface of the pipes, and ensuring the structural service life. For buildings in special environments, such as those exposed to corrosive gases, specific provisions must be made in the design for the protective layer of the concrete structures' flat-end concrete pipes to ensure the durability of the building structure.

(3) Ensure the flat-end cement pipe is protected from high temperatures to guarantee structural safety.

The protective layer has thickness, which allows the building structure to be protected from rapid loss of bearing capacity and collapse due to high temperatures or in the event of a fire, ensuring that Heze Pingkou cement pipes remain unaffected by the heat.

Above is the introduction from Zhengzhou Cement Pipe manufacturer regarding the main functions of the protective layer for cement pipes, which has significantly improved the load-bearing performance, compressive strength, and fire resistance of the cement pipes. We hope our introduction can be helpful to all.
