Q:What are the different types of thrust restraints for ductile iron pipe?: There are several different types of thrust restraints that can be used for ductile iron pipe installations. These thrust restraints are designed to prevent the pipe from moving or separating under the forces generated by internal pressure, external loads, or changes in temperature. 1. Thrust blocks: Thrust blocks are concrete structures that are typically installed at bends, tees, and other changes in direction in the pipeline. They are designed to resist the thrust forces by transferring them to the surrounding soil or foundation. 2. Mechanical restraints: Mechanical restraints, such as tie rods or harnesses, are used to restrain the pipe by exerting an external force on it. These restraints are typically made of steel and can be adjusted to accommodate changes in pipe length or alignment. 3. Pipe anchors: Pipe anchors are devices that are installed at specific intervals along the pipeline to provide resistance against axial movement. They are usually made of steel and are embedded into the surrounding soil or concrete to provide a secure anchor point for the pipe. 4. Thrust collars: Thrust collars are devices that are installed around the pipe to prevent it from moving or separating. They are typically made of steel and are placed at strategic locations along the pipeline to absorb the thrust forces. 5. Restrained joint systems: Restrained joint systems are specialized pipe joints that are designed to resist axial forces. These joints typically have additional features, such as keyways or wedges, that provide resistance against movement. It is important to select the appropriate type of thrust restraint based on the specific requirements of the ductile iron pipe installation. Factors such as the pipe diameter, operating pressure, soil conditions, and potential external loads should be considered when determining the most suitable thrust restraint system. Consulting with a qualified engineer or pipe manufacturer can help ensure the proper selection and installation of thrust restraints for ductile iron pipe.

Q:Does the cast iron have size 250? What's the performance?: Ductile iron does not have size 250.
