A configuration of tightening operations designed for round bolted joints containing thirty-six fasteners. This methodology ensures even distribution of clamping drive throughout the linked surfaces. An instance could be tightening the bolts on a big flange in a round sequence, usually in a number of passes at incrementally rising torque values, to attain a particular pre-load on every bolt.
The applying of an outlined sequence for tightening fasteners gives substantial benefits in structural integrity and operational lifespan. Constant tensioning reduces the probability of leaks, prevents distortion of joined parts, and mitigates the danger of untimely failure as a consequence of uneven stress. Traditionally, these strategies developed from empirical statement and have been refined via engineering evaluation to optimize joint efficiency.
