Q: Can ductile iron pipes be used in dam or reservoir projects?: Yes, ductile iron pipes can be used in dam or reservoir projects. Ductile iron pipes are known for their strength, durability, and corrosion resistance, making them suitable for various applications, including water distribution and transmission systems. In dam or reservoir projects, where the pipes need to withstand high pressure and carry large volumes of water, ductile iron pipes are often preferred. They have excellent mechanical properties, including high tensile strength and impact resistance, which ensure their ability to handle the load and provide a reliable and long-lasting solution. Additionally, ductile iron pipes are also adaptable to various installation methods, including trenchless techniques, making them a versatile choice for dam or reservoir projects.

Q: What is the expected deflection limit of ductile iron pipes?: Several factors, including pipe diameter, wall thickness, and soil conditions, determine the expected deflection limit of ductile iron pipes. According to industry standards, it is recommended that ductile iron pipes used for underground installations should not exceed a deflection limit of 2%. In other words, the maximum allowable deflection would be 2% of the pipe's diameter. It is important to be aware that surpassing the deflection limit can result in various issues, such as reduced flow capacity, higher chances of pipe failure, and compromised structural integrity. Therefore, it is crucial to carefully consider and adhere to the suggested deflection limits when designing and installing ductile iron pipes to ensure their long-term performance and reliability.
