Ductile cast iron pipe, also known as ductile iron pipe or DI pipe, is a type of piping commonly used for water and wastewater applications. It is made from cast iron with added graphite nodules, which give it increased flexibility, strength, and durability compared to traditional cast iron pipes. Ductile cast iron pipes are known for their resistance to corrosion, abrasion, and internal pressure, making them ideal for transporting water over long distances and under high pressure. With excellent mechanical properties and a long service life, ductile cast iron pipes are a reliable choice for various infrastructure projects, including water distribution systems, sewer lines, and industrial pipelines.
Mechanical Joint (MJ): This method involves using mechanical joints consisting of a gland, gasket, and bolts/nuts to connect two pipes together. The gland and gasket create a watertight seal, while the bolts and nuts secure the joint.
Push-On Joint: In this method, the spigot end of one pipe is inserted into the socket end of another pipe. A rubber gasket in the socket provides a seal, and no additional materials or tools are required for installation.
Flanged Joint: Flanged joints involve connecting pipes using flanges and bolts/nuts. The flanges are attached to the ends of the pipes, and the bolts/nuts are tightened to compress a gasket between the flange faces, creating a seal.
Restrained Joint: Restrained joints are used in applications where pipes need to resist movement or thrust forces. These joints typically include additional components such as harnesses, rods, or restraints to secure the pipes in place.
