A specific sequence of tightening bolts on a circular plate with eight bolt holes, typically used to connect pipes or other components, ensures even distribution of pressure across the gasket surface. This method commonly employs a crisscross or star-shaped order to progressively compress the joint. Following the designated order helps to prevent leaks and maintain structural integrity. An example would be tightening bolts in the sequence 1-5-3-7-4-8-2-6, incrementing in stages of increasing torque value until the final specified torque is achieved.
The use of a prescribed tightening sequence is vital for maintaining a secure and leak-proof seal. Uneven tightening can lead to gasket failure, distortion of the flange, and potential system downtime. This approach has evolved from practical experience and engineering principles, becoming a standard practice in industries where fluid or gas containment is critical. Proper implementation contributes to increased operational safety and reduced maintenance costs over the lifespan of the connection.
