Q: How much is the installation fee of the 400 largest ductile iron pipe?: Compared with the PE pipe, from the installation time, ductile pipe PE pipe installation is simple and rapid, and after the installation of internal and external pressure bearing better tightness and corrosion resistance; from the point of view, ductile pipe sealing better after installation, but also can improve the corrosion resistance through various anti-corrosion methods;

Q: How do ductile iron pipes perform in high-pressure applications?: Ductile iron pipes are known for their exceptional strength and durability, making them highly suitable for high-pressure applications. These pipes are designed to withstand immense internal and external pressures, making them well-suited for underground or above-ground installations where high-pressure conditions are expected. One of the key advantages of ductile iron pipes in high-pressure applications is their ability to resist cracking or bursting. The inherent ductility of the material allows it to absorb and distribute the pressure evenly, minimizing the risk of failure under high-pressure conditions. This makes ductile iron pipes a reliable choice for water supply systems, oil and gas pipelines, and other applications where the pipe is subjected to significant pressure. Additionally, ductile iron pipes have excellent corrosion resistance properties, which further enhances their performance in high-pressure environments. The pipes are typically coated with a protective layer, such as cement mortar or epoxy, which acts as a barrier against corrosion. This protective coating prevents the formation of rust or scale inside the pipe, ensuring a smooth flow and maintaining the structural integrity even under high-pressure conditions. Furthermore, ductile iron pipes have a high tolerance for external loads, such as soil pressure, traffic loads, or other external forces. This strength enables them to withstand the additional stress that may be present in high-pressure applications, ensuring the long-term reliability and performance of the pipe system. Overall, ductile iron pipes offer exceptional performance in high-pressure applications. Their strength, durability, corrosion resistance, and ability to withstand external loads make them a reliable choice for various industries and infrastructure projects where high-pressure conditions are a concern.

Q: Do ductile iron pipes have inner enamel?: For fire water and living water supply, low requirement is lined with cement mortar, some high can be lined with epoxy resin, epoxy ceramic lining, as well as cement mortar lining epoxy sealing layer (compromise is the price of blame).
