Which tool would a steamfitter commonly use for bending pipes?

A steamfitter commonly uses a pipe bender for bending pipes. This tool is specifically designed to create arcs and curves in pipes, allowing for proper alignment when connecting different sections of piping. The pipe bender can accommodate various sizes and types of pipes, facilitating the installation process in tight or complex spaces.

In contrast, a pipe wrench is primarily used for gripping and turning pipes, not bending them. A tape measure is essential for measuring lengths and ensuring accurate cuts, but it does not assist in bending. A flare tool is used to create a flared end on a pipe, which is essential for certain types of connections, but it is not intended for bending. Thus, the pipe bender stands out as the appropriate tool for this specific task, highlighting its importance in the steamfitting trade.
