The pipe wrench can clamp the pipe and make it rotate to complete the connection. The working principle is to convert the clamping force into torque. The greater the force used in the twisting direction, the tighter the pipe can be clamped.
The jaws of the pipe wrench have a taper of 30 ~ 80 to increase the torque, tighten the pipe and prevent slipping. The movable jaw on the pipe wrench is "swingable" when it is opened, so the size of the opening is only the same as the outer diameter of the pipe fitting. If the opening is larger than the outer diameter of the pipe fitting, it is difficult to clamp it on the pipe fitting.
When turning the pipe wrench, be sure to pay attention to the opening direction of the pipe wrench consistent with the direction of force. If the direction of force is different from the direction in which the pipe fitting needs to be tightened or loosened, the pipe wrench should be removed from the pipe fitting and "turned over" before operation.

Matters needing attention when using pipe tongs:
First of all, we must choose the appropriate specifications; Also adjust the opening of the pliers head to make it equal to the diameter of the workpiece; Pay special attention to the clamp head to clamp the workpiece and then pull it hard to prevent slipping and hurting people; When using the booster, the length should be appropriate. When moving the handle, pay attention to the bearing torque, and don't use too much force to prevent overload damage; Of course, the pliers teeth and adjusting ring must be kept clean;
Try not to butter the teeth of the pipe wrench to prevent slipping during use and cause safety accidents. Also, the pipe wrench must not be used as a hammer, especially the pipe wrench should not clamp the workpiece with the temperature exceeding 300℃.
