To ensure safety and integrity, a reliable tool like the Flange Bolt Torque Calculator becomes indispensable. This article presents a user-friendly calculator and guides you through its usage, formula, examples, FAQs, and concludes its significance.
How to Use
- Enter the required parameters in the designated fields.
- Click the “Calculate” button to obtain the torque value.
- Ensure all inputs are accurate for reliable results.
Formula
The torque required for tightening flange bolts can be calculated using the following formula:
Where:
- T is the torque in foot-pounds (ft-lbs).
- K is the coefficient of friction.
- F is the bolt tension force in pounds-force (lbs).
- D is the bolt diameter in inches.
- R is the thread pitch diameter in inches.
Example Solve
Let’s say we have a bolt tension force F=5000 lbs, bolt diameter D=0.5 inches, thread pitch diameter R=0.3 inches, and a coefficient of friction K=0.2.
Using the formula:
So, the required torque would be approximately 138.89 ft-lbs.
FAQ’s
Q: Why is accurate torque important for flange bolts?
