What is the function of a reamer in pipe threading?

A reamer is a tool specifically designed to enlarge and smooth the internal diameter of a pipe, making it an essential instrument in pipe preparation before threading. When a pipe has been cut, it may have rough edges or burrs that can lead to improper fit and potential leaks. The reamer effectively removes these imperfections from the inner surface, ensuring a smoother passage for fluids and a better seal when fittings are subsequently attached. This enhanced internal surface of the pipe aids in maintaining fluid flow and reducing turbulence.

The function of a reamer is distinct because it focuses on the internal aspects of the pipe rather than creating threads or joining sections. It is instrumental in preparing pipes for connections, especially in plumbing systems that require precise fittings for optimal performance. This emphasis on internal diameter smoothness is crucial for preventing obstructions and ensuring a reliable plumbing system.
