The ANSI flange is a dynamic
joint which, when bending forces and tensile loads are applied,
become loose and leak.
• Complex
bolting requiring complex bolting equipment – HIGH
COST
• Large flange diameters, difficult to work with, more space required,
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 |
