Pipe wrenches are generally used to grip and rotate steel pipe tools. Pipe wrenches manufactured by Emerson Pipe Tools are widely used in oil pipelines and civil pipeline installations. The Pipe wrench can complete the connection by clamping the pipe to make it rotate. The working principle is to convert the clamping force into torsion force. The larger the force in the twisting direction, the tighter the pipe can be clamped.

How does the Pipe wrench work?
The clamping and rotation of the Pipe wrench are realized by the friction between the pipe fitting and the chain wound around it, and the torsion force is generated by the meshing force of the local cone at the front end of the clamp handle and the chain, and the clamp handle is not applied on the surface of the pipe fitting. force point. At present, the new Pipe wrench can not only clamp and rotate metal pipe fittings, but also ceramic pipe fittings, thin-walled pipe fittings, plastic pipe fittings, etc., without causing bite marks and damage to the surface of the pipe fittings.
What are the usage and precautions of Pipe wrench?
1. to choose the appropriate specifications
2. The opening of the pliers should be equal to the diameter of the workpiece;
3. The pliers should clamp the workpiece and then pull hard 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. The teeth and adjusting ring of the Pipe wrench should be kept clean.
When using a Pipe wrench, you should first check whether the fixing pin is firm, whether there are cracks in the clamp head and clamp handle, and those with cracks cannot be used; the smaller Pipe wrench cannot be used with excessive force, and cannot be used with an afterburner. Use as a hammer or crowbar. In addition, wash it in time after use, apply butter to prevent the rotating nut from rusting, and put it back on the tool rack or in the tool room.
What should be paid attention to when using Pipe wrench?
The Pipe wrench can complete the connection by clamping the pipe to make it rotate. The working principle is to convert the clamping force into torsion force. The larger the force in the twisting direction, the tighter the pipe can be clamped.
Pipe wrench jaws have a taper of 30-80 to increase torque and grip the tube so that it does not slip. The movable jaw on the Pipe wrench has a certain "swingability" when it is opened, so the size of the opening only needs to be 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 twisting the Pipe wrench, be sure to pay attention to the opening direction of the Pipe wrench and the direction of force. If the direction of force and the direction in which the pipe fittings are tightened or loosened are not correct, the Pipe wrench should be removed from the pipe fittings and then "turned over" before operating.
