1. Pre-installation Preparation: Clean oil and debris from the contact surfaces. Select bolts of matching specifications and strength, ensuring the nuts are perpendicularly fitted to the flange face to prevent slippage and uneven stress.
2. Standardized Tightening Procedure: Use a diagonal staggered tightening method, gradually applying load in at least three stages, progressing from 50% to 80% to 100%. Finally, tighten again under full load along the circumference to ensure consistent stress along the flange's circumference.
3. Use Appropriate Tools: Use a box wrench for general applications, and a torque wrench or bolt tensioner for critical conditions. Precisely control the preload of each nut to avoid manual force deviation.
4. Optimized Structural Design: Prioritize toothed flange nuts, using the flange to distribute pressure. Suspension nuts, grooved nuts, and other structures can also be used to achieve a more even distribution of thread load.
