How should pipe ends be prepared before installation?

Preparing pipe ends before installation is crucial for ensuring a proper fit, effective sealing, and overall system integrity. When pipe ends are square, reamed, and free of burrs, they allow for a better connection with fittings or other pipe segments. This precision in preparation minimizes the risk of leaks and enhances the strength of the joint.

Squaring the ends allows them to meet properly, which is essential for the alignment of subsequent fittings. Reaming is the process of smoothing out the inside edge of a pipe after cutting, which helps prevent the formation of burrs and sharp edges. Burrs can interfere with flow and create points of turbulence that may lead to wear and tear over time.

Additionally, ensuring the ends are clean and free from any debris is essential, as contaminants can impede the sealing process. Therefore, following the correct procedure for preparing pipe ends guarantees a reliable and durable installation, which is fundamental in mechanical systems adhering to the North Carolina Mechanical Code.
