Arrangement of flange bolts
Thread Content
1. If the nominal diameter of the bolt exceeds 56 mm, how should LA, Le, and L be selected? 2. In a sealing structure: can the center circle of the bolts at the end of the cylinder, which is sealed by metal flat gaskets, be calculated using a flange? 3. For the metal flat gasket-sealed cylinder end, the depth h1 of the screw holes should be increased by the length required for the manufacturing process. Are there any requirements or standards regarding this required length? I would appreciate your guidance. Thank you~
