The Tightening Calculator that we put at your disposal free of charge allows you in a few clicks to select the right tool for the tightening to the torque that you have to perform. After choosing the HYTORC hydraulic wrench from your fleet of equipment or identifying the tool you will need to rent or buy, the Calculator will tell you the pressure to set on the pump to apply the desired torque. With this torque calculator you have access to the entire range of HYTORC hydraulic wrenches for your selection. There are two possible functions: the Bridle Calculator which is the most advanced and the Simple Calculator.
We wanted this calculator to be as simple as possible so that it would be useful to you and allow you to quickly get an answer and a result without needing to look for papers or get out a calculator. With a lot of visual elements you’ll be able to know the setting of your pump for the torque you’ve been asked to apply to the bolts to be tightened. If you have no idea of the tightening torque for your operation but a tension effort, you’ll be able to determine a torque based on the grease you have available to put on the bolt. Finally, if you just know the size of your bolts and their material, you’ll be able to play on their percentage of use you want and the greasing to determine the torque first and the hydraulic wrench to use next with the pressure setting that will be given automatically.
The idea behind the Flange Tightening Calculator is to give you a summary sheet of all the useful information for tightening on site, and for this sheet to guide you through the tightening operation. This synthetic, visual sheet will summarize all the information on the flange bolts: number of bolts, diameter, dimension on flats and material, then all the information on tightening intensity: percentage of use, coefficient of friction, tension and tightening torque, with the corresponding pressure to be set on the pump. Finally, depending on the number of hydraulic wrenches used at the same time, the flange sheet will summarize the tightening sequence with the number of passes to be made and, for each, the torque and pressure setting for the selected wrench model. Visually, you’ll find the flange diagram with the numbering of the bolts corresponding to the sequence.
This very quick and simple tool lets you know what the torque and pressure setting is for a specified bolt size. You choose the bolt size and material, its percentage of use and the grease you’re going to apply to it, and the Calculator gives you the resultingTorque Tightening. Then all you have to do is select the hydraulic wrench from the entire HYTORC range and the Torque Calculator will present you with a summary sheet with the pressure to be set to apply the torque determined with these few parameters.
