Flange Management for bolted flange joints
Flange Management B.V. helps asset owners, contractors, inspectors and engineers manage bolted flange joints from calculation to documented evidence.
We support the complete flange management process: selected joint data, torque values, Preparation Summaries, Flange Protocols, Engineer-reviewed Calculation Reports and traceable documentation for inspection, QA and project handover.
FlangeUp® is the calculation and dossier platform of Flange Management B.V. It provides a fast digital entry point for one flange joint, while Flange Management B.V. provides the engineering review, documentation discipline and project support for larger scopes.
Calculate and prepare
Use FlangeUp® to calculate flange joint preparation values, including torque, residual bolt load and residual bolt stress.
Save the result as a dossier and generate a Preparation Summary for the selected flange joint.
Project documentation
Structured calculation packages for flange lists, shutdown scopes, turnaround dossiers, QA files and EPC deliverables.
We help turn flange data into reviewed, traceable documentation for your project file.
FlangeUp® digital workflow
Use FlangeUp® for a Free Basic Report, free Flange Protocol, single engineer-reviewed calculations or as a digital intake for larger project scopes.
Start online for one flange joint, create a practical Flange Protocol from the saved data, or request project pricing for multi-joint calculation packages.
More than torque values
Flange management is not only calculating a torque value. It is the controlled process of selecting the joint data, preparing the tightening values, documenting the flange protocol, recording the evidence and making the calculation available for inspection or engineering review.
FlangeUp® supports this process by turning selected flange data into a traceable dossier. A dossier can include calculation values, a Preparation Summary, Flange Protocol data, Engineering Review status and an Engineer-reviewed Calculation Report.
For one flange joint, customers can start directly online, create a free account and save the calculation as a dossier in My Flange Management.
For larger scopes, Flange Management B.V. supports flange lists, shutdowns, turnarounds, QA packages, maintenance dossiers and recurring engineering review work.
What we deliver
Depending on the scope, our deliverables can include Preparation Summaries, Flange Protocols, Engineer-reviewed Calculation Reports, calculation review, input checks, traceable evidence records, summary tables, exception lists, revision handling and project documentation support.
Our calculation and review routes include ASME/API flange routes and EN 1092-1 / EN 1591-1 workflows, depending on the selected flange joint, calculation method and available input data.
Why this matters
When a flange joint is questioned, engineers need more than a number. They need to know what was selected, what was calculated, what was reviewed and what has been released.
Incomplete or unclear records can create issues during QA review, maintenance planning, inspection, handover or incident review.
Independent by design
Flange Management B.V. operates independently of bolt suppliers, gasket manufacturers and assembly contractors. Our role is to support engineering correctness, clear documentation and defensible calculation evidence.
