Large-Diameter Blind Flange Isolation
Closure, maintenance isolation, pressure testing and reserved interfaces for petrochemical, energy and large industrial pipelines.

Engineering Application
Closure, maintenance isolation, pressure testing and reserved interfaces for petrochemical, energy and large industrial pipelines.
Solution Overview
Blind flanges provide physical isolation during equipment maintenance and pipeline construction. They also close line ends and support pressure testing, with rating and sealing selected to project parameters.
Installation Positions
- Plant mains and equipment inlets or outlets
- Pipeline ends and reserved connections
- Temporarily inactive branches
- Isolation points during equipment maintenance
- Pipeline pressure-test sections
Engineering Problems Addressed
- Creates a sealed boundary for pressure testing
- Stops hazardous media during maintenance
- Prevents debris from entering inactive pipelines
- Reserves interfaces for future equipment or line extensions
