What is the maximum size pipe that a lag screw rod can support?

The maximum size pipe that a lag screw rod can support is 8 inch pipe. This standard is based on various factors, including the load distribution and the strength of the materials used in both the pipe and the supporting structure.

In typical sprinkler systems, lag screw rods are used to provide a secure means of hanging or supporting piping. The choice of an 8 inch pipe aligns with industry standards, which stipulate that various supporting equipment, including rod and hanger systems, have specific limits based on the size and weight of the piping they are meant to support.

For pipes larger than 8 inches, additional considerations, such as increased weight and load distribution, require more robust support systems that might include larger diameter hangers or a different type of fastener altogether. Therefore, while smaller pipes can be adequately supported by lag screw rods, the limitation for an 8 inch pipe reflects an understanding of structural integrity and safety in the installation of sprinkler systems.
