Quick Opening Closures

Quick opening closures are pressure retaining structures designed to provide access to pipelines and pressure vessels.
Approved Design ASME VIII Div.1.states that “Quick-actuating or quick opening closures are those that permit substantially faster access to the contents space of a pressure vessel than would be expected with a standard bolted flange connection.

Typical applications for the ROC quick opening closure include
• Pig launchers and pig receivers
• Filter vessels
• Metering skid systems
• Strainers
• Separators
