Which type of wrench is typically used to tighten a pipe?

A Stillson wrench is specifically designed for gripping and turning pipes, making it the ideal tool for this task. Its unique design features serrated jaws that provide an effective grip on rounded surfaces, such as pipes, which can be challenging to secure with other types of wrenches. The adjustable jaw allows for a range of pipe sizes to be effectively engaged and turned.

Socket wrenches are commonly used for fasteners like nuts and bolts rather than pipes. Torque wrenches are engineered to apply a specific torque to a fastener, and while they are very useful in mechanical applications, they are not primarily intended for gripping pipes. Adjustable wrenches can also work on pipes to some extent, but they lack the specialized gripping capability of a Stillson wrench, which is purpose-built for this specific application.
