CIRCOR Energy Pipeline and Pressure Vessel Closures (ROC and ROCII) Brand: Pipeline Engineering

Quick opening closures are pressure retaining structures designed to provide access to pipelines and pressure vessels. ROC closures provide safe and quick access to pipeline and pressure vessels. They are built to meet all required international design codes and can be used in horizontal, vertical, inclined or declined applications. 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." The Pipeline Engineering ROC quick opening closure meets this standard. Applications Pig launchers and pig receivers Filter vessels Metering skid systems Strainers Separators
