Hydraulic pipe benders make use of hydraulic pressure to bend different sizes of pipes and tubes to specific angles. The process is easy to understand. Hydraulic pipe benders are usually simple and can be used with ease without any technical training required.
Usually pipe benders have a series of rollers through which the pipe is fed into. The pipe moves forward so that the part to bend is in between the shoe and the roller. The user pulls the handle to move the shoe in a circular motion around the roller. As the handle is pulled the pipe is forced around the roller acquiring the round or bent shape.
Pressure must be applied to force the pipe around the roller and to give bend it to the desired angle. This is where the hydraulic system comes in handy. While pulling the handle, a hydraulic piston moves the shoe and thus applies high pressure on the pipe forcing it around the roller.
As the shoe is moved back to the original position, the piston retracts to the original position lowering the pressure applied on the pipe. When another pipe is added to the system, again the piston pushes against the hydraulic liquid causing high pressures to be exerted on the pipe and forcing it to bend.
Hydraulic pipe benders are advantageous because;
Hydraulic pipe benders can be used to work bend pipes of different thicknesses simply by changing the shoe and roller. This versatility allows you to work on different thicknesses without deforming the pipes.
