Witrynatorque valve Table-SAEP-351-02.The first stage should be more than 30% of the final torque. The final torque shall be within + 5% of the required torque values. Apply the torque evenly to each stud bolt tightening sequence. The final torque must be within +. 5% of the required values per stud bolt tightening procedure. WitrynaThe tightening force will be gradually increased in the different stages of the tightening process as indicated in table 1 of the standard. The use of lubricants is recommended on uncoated bolts since it reduces the coefficient of friction resulting in a lower torque value. It is necessary to ensure that the lubricant is compatible with the ...
