Many Woden customers asked about the Woden Hydraulic Torque Wrench calibration issues.

Although there are other ways of establishing the tension on a bolt, regarding the Hydraulic torque wrenches have an unparalleled advantage in bolt tightening methods and preload control.hydraulic torque wrench is used most often.

In term of the  industrial production, infrastructure construction and other applications more and more widely,and also hydraulic torque wrench calibration increasingly demanding. 

Some of Woden's customers think that there is no need to make the hydraulic torque wrench calibration. This thought is very dangerous.

Woden must say any kind of fastening and tightening devices , with the damage of the equipment, the tightening torque will change, hydraulic torque wrench can not be excluded.

After the hydraulic torque wrench are used many times,some of the accuracy is not guaranteed,but Woden promised that in 70Mpa Max working pressure and the accuracy of Woden hydraulic torque wrench keeps within ±3%.

Woden will take the responsiblity to tell the hydraulic torque wrench operator the calibration cycle.

Generally, Woden suggest calibrate once a year or when the hydraulic torque wrench is used 5000 times.

Many Woden hydraulic torque wrench customers will ask the cost of the hydraulic torque wrench calibration.

Woden is honoured to answer this question,the expenses of the hydraulic torque wrench calibration is based on the torque of the hydraulic torque wrench.

The torque is large ,then large torque sensor will be used.As we all know,the Torque Sensore is larger,the cost will be higher.

WODEN hydraulic pressure as hydraulic equipment industry leader, not only pay attention to quality control hydraulic wrenches, hydraulic tensioners, hydraulic wrench pumps and other hydraulic tools,

as well as domestic manufacturers of hydraulic equipment and the majority of wind power, nuclear power, heavy industry provide torque testing and calibration services.

While WODEN long-term cooperation with professional calibration testing organizations, make sure to check and verify the results meet the industry standards.
