VECTOR | SPO Compact Flange - The Case Against ANSI
The case against ANSI
The ANSI flange is a dynamic joint which, when bending forces and tensile
loads are applied, become loose and weak.• Complex bolting requiring complex bolting equipment - Result : High Cost.
----------------------------------------------------------------------------------------------------------------------------------------------------
• Large flange diameters are difficult to work with, require more space and result in a complex handling
----------------------------------------------------------------------------------------------------------------------------------------------------
• Gap created by raised face introduces corrosion problems
----------------------------------------------------------------------------------------------------------------------------------------------------
• Large bolt forces to maintain gasket integrity
----------------------------------------------------------------------------------------------------------------------------------------------------
• Excessive costs for large flange diameters in exotic materials
----------------------------------------------------------------------------------------------------------------------------------------------------
• Regular re-tightening incurs increased life cycle costs
