Safe Use Of Pipe Wrenches

The American Type Pipe Wrench can be rotated to complete the connection by clamping the pipe. The working principle is to convert the clamping force into the torque, and the force used in the twisting direction can clamp the pipe tighter. The following small series will introduce the common sense of pipe wrenches.

Pipe wrenches, generally used to clamp and rotate steel pipe tools, increase the torque with the taper of the jaws, usually taper at 3-8 degrees, bite the tube, automatically adapt to different pipe diameters, automatically adapt to the jaws applied to the pipe Plastic deformation caused by stress. Torque is guaranteed without this slip under this effect.

Precautions for the use of German Type Pipe Wrench.

1, to choose the appropriate specifications;

2, the jaw opening should be equal to the diameter of the workpiece;

3. The clamp head should be tightened after the workpiece is clamped to prevent slipping;

4. When using the afterburner, the length should be appropriate, and the force should not be too strong or exceed the allowable strength of the pipe wrench;

5. Keep the teeth and adjustment ring of the pipe wrench clean.

When using the pipe wrench, first check whether the fixing pin is firm, whether there is crack in the clamp head or the clamp handle, and those with cracks cannot be used; the smaller pipe wrench can not be used too much, can not be used with the force bar, can not be used Use as a hammer or crowbar. In addition, wash it in time, apply butter, prevent the rotating nut from rusting, put it back on the tool holder or in the tool room.
