According to Wikipedia, Pipe wrench is an adjustable wrench/spanner used for turning soft iron pipes and fittings with a rounded surface. The design of the adjustable jaw allows it to lock in the frame, such that any forward pressure on the handle tends to pull the jaws tighter together. Teeth angled in the direction of turn dig into the soft pipe.

Pipe Wrenches are usually used to grasp pipes and other curved surfaces. Solid housings and hardened steel jaws provide excellent bite and grip.

The jaws of a pipe wrench will not stay parallel, but the jaws will form a triangular grip on the pipe and may get locked/stuck onto the pipe. They are not intended for use on hardened steel hex nuts or other fittings because they would ruin the head; however, if a hex nut is soft enough that it becomes rounded beyond use with standard wrenches, a pipe wrench is sometimes used to break the bolt or nut free.

Pipe wrenches are classified by the length of the handle; they can be available in any size from as small as 3 inches up to 48 inches or larger. They are usually made of cast steel. Today, aluminium is also used to construct the body of the wrench, while the teeth and jaw remain steel. Teeth, and jaw kits (which also contain adjustment rings and springs) can be bought to repair broken wrenches, as this is cheaper than buying a new wrench.

Additionally, there are several tips for using this tool:

Always pull rather than push a pipe wrench handle.
Maintain a gap between the back of the hook jaw and the pipe. This helps maximize gripping force and centers the pressure on the jaw teeth.
Always wear eye protection.
Do not use a pipe wrench to bend, lift or raise pipe.
