Standard Conditions for Torque Calculations

 

a)  The torque values provided above should be used with caution. Engineering judgment and experience is 

needed to allow for proper interpretation. Due to the inherent variations in the coefficient of friction, both 
in the threads and between the nut face and clamped surface, there is no single “correct” tightening 
torque for all circumstances.

 

 
A range of values can be determined however given the anticipated frictional scatter. The amount of 
frictional scatter, which the engineer allows for when determining the clamp force and tightening torque, 
should be based upon experimental results taken from the application. 

 

b)  Recommended torque values do not consider piping stress or alignment.

 

 

c)  Consult ZOOK for recommended torque values for non-standard conditions.

 

 

Actual field conditions may differ from room temperature conditions on which the above torque values are based 
on. In addition, these values are based on raised face welding neck flanges, free running treads and well 
lubricated bolts with a coefficient of friction of µ =0.180, 1/8” thk compressed fiber gaskets with design seating 
stress (y) of 4400 psi and gasket factor (m) of 5.2. Re-torqueing of bolts may be necessary to nullify loss caused 
by gasket compression set. ASME Code Sect. VIII Div. 1 was followed for estimating required seating and 
operating bolt loads.
