Why are mechanical joints frequently used in ductile iron pipe connections?

Mechanical joints are frequently used in ductile iron pipe connections primarily because they ensure high strength in the joints while maintaining the integrity of the pipe structure. These joints are designed to provide robust and reliable connections that can withstand the internal pressures and environmental conditions typically faced in water distribution systems.

The strength of mechanical joints is critical, especially in situations where the system may experience shifts due to soil movement, temperature changes, or other external factors. This strength contributes to the overall durability and longevity of the pipe system, making it less prone to failures or leaks over time.

While other factors, such as installation ease and flexibility, may also play roles in the choice of joint types, the primary advantage of mechanical joints in ductile iron pipes is their ability to create a strong, dependable connection that secures the integrity of the water distribution network.
