o ensure accurate application. Follow a cross-tightening pattern (e.g., star pattern) to evenly distribute load. Apply torque gradually in multiple passes rather than all at once. Lubricate threads appropriately to reduce friction and achieve consistent torque. Ensure flange surfaces are
c flange rating and application. Use calibrated torque tools. Document procedures and results for traceability. Regularly review and update procedures based on new standards or technological advances.
