Flange Bolt-Up - Bolting Torque Tables
The torque tables are built on specific assumptions regarding bolt and nut factor. Before using a given torque table, these assumptions should be verified to insure they are appropriate for the specific application.
Even if all assumptions are appropriate, results may vary depending on actual conditions. Many factors induce scatter in the results or increase the inherent variability in the bolting process. These include variations in the nut factor; bolt, flange and nut condition; equipment calibration and condition; perpendicularity of the bolt, nut and flange; etc.
The values in the tables are based on the equation:
S=  Fkd
12
Where:
T = Torque value, (ft-lbs)
F = Bolt pre-load, (lbs)
k = Nut Factor based on lubricant used
d = Nominal bolt diameter, (in.)
The nut factor is not the coefficient of friction.
It is an experimentally derived constant that includes the impact of friction.

NOTES:
  • This Table is applicable to Never-Seize paste and Fel-Pro lubricant, K=0.16.
  • The above Table is applicable only for ASTM A320 Grade B8, Class 2 and A193 Grade B8, Class 2 Stud Bolts. These are 304 SS material.
  • The torque values are approved for spiral wound graphite and PTFE filled gaskets, graphite sheet gaskets GHE and GHR types, ring joint, double jacketed and Kammprofile gaskets.
  • The Final Torque Value accounts for 10% bolt relaxation.
  • The yield strength for strain-hardened bolts varies with diameter. Torque values for bolts greater than 1 1/2 in. diameter are based on 30 ksi yield strength.
