Torque Tightening Manufacturer’s rating of pressure and torque are maximum safe limits. Good practice encourages using only 80% of these ratings! Torque Procedure Select the Correct Wrench Choose your Enerpac torque wrench using the untightening rule of thumb: • When loosening a nut or bolt more torque is usually required than when tightening. • For general conditions it can take up to 2½ times the input torque to breakout. • Do not apply more than 75% of the maximum torque output of the tool when loosening nuts or bolts. When torquing it is common to tighten only one bolt at a time, this can result in Point Loading and Load Scatter. To avoid this, torque is applied in stages following a prescribed pattern: Torque Sequence 1 1 1 5 12 5 8 9 8 4 3 3 4 4 3 10 6 2 7 7 2 Step 1: Spanner tight ensuring that 2-3 threads extend above nut Step 2: Tighten each bolt to one-third of the final required torque following the pattern as shown above. Step 3: Increase the torque to twothirds following the pattern shown above. 11 6 2 Step 4: Increase the torque to full torque following the pattern shown above. Step 5: Perform one final pass on each bolt working clockwise from bolt 1, at the full final torque. Conditions of Bolted Joints • Humidity corrosion (rust) requires up to twice the torque required for tightening. • Sea water and chemical corrosion requires up to 21⁄2 times the torque required for tightening. • Heat corrosion requires up to 3 times the torque required for tightening. Minimum Output Torque • The recommended minimum torque value of a hydraulic wrench is 10% of the maximum rated value. Breakout Torque Bolting Integrity Software A comprehensive on-line software solution for Bolted Joint Integrity. Integral databases hold data for: When loosening bolts a torque value higher than the tightening torque is normally required. This is mainly due to corrosion and deformations in the bolt and nut threads. • ASME B16.5, ASME B16.47, API 6A and API 17D flanged joints • Common gasket materials and configurations • Comprehensive range of bolt materials • Comprehensive range of lubricants • Enerpac's Controlled Bolting Equipment including: Torque Multipliers, Hydraulic Wrenches and Bolt Tensioning tools Custom Joint information can also be entered. Breakout torque cannot be accurately calculated, however, depending on conditions it can take up to 2½ times the input torque to breakout. The use of penetrating oils or anti-seize products is always recommended when performing breakout operations. The software offers Tool selection, Bolt Load calculations and Tool pressure settings, as well as, a combined Application data sheet and Joint completion report. 123
