About us
Flange Management is an independent Dutch engineering firm based in Amsterdam, specializing in joint integrity within the energy, oil & gas, and petrochemical industries. With deep expertise in flange technology, we understand the unique challenges our clients face and deliver solutions that ensure safe, efficient, and uninterrupted operations.
We are committed to improving the reliability, integrity, availability, and longevity of flange connections. By significantly reducing unplanned shutdowns caused by leaking joints, we help our clients save valuable time, resources, and operational costs.
We provide precise flange calculations that safeguard the quality of pipework systems and enable continuous verification of flange integrity — even while installations remain in operation. By enhancing the quality and durability of flanged joints, our approach establishes a traceable foundation for long-term asset reliability and measurable cost reduction.
Mission statement
Delivering Leak-Free Solutions
A flange connection is a sophisticated mechanical system. Achieving a leak-free joint requires precision, expertise, and control—every decision, from design to tightening, must fall within strict engineering limits.
At Flange Management, we turn complexity into clarity. Every calculation generated by our proprietary FlangeUp® software is rigorously reviewed by qualified engineers to ensure accuracy, repeatability, and compliance with international standards.
Flange Management — General
Plant owners face growing pressure to reduce fugitive emissions under tightening environmental regulations, safety demands, and performance expectations. The cost of leakage—product loss, cleanup, fines, and reputational damage—is high.
Flange Management provides a complete suite of engineering services to minimize these risks and to ensure leak-free start-ups and sustainable operation.
Our verified calculations determine the correct bolt preload, torque, gasket stress, and assembly limits, forming the foundation for a secure seal. We help asset owners make informed design decisions and implement the right procedures to achieve measurable reliability improvements.
Joint integrity
Mechanical failure caused by design or material degradation is the second most common source of flange joint issues. Most fugitive emissions originate from joints that were either miscalculated or improperly assembled.
Through our work, Flange Management ensures that each flange joint is calculated, verified, and documented to withstand its operational stresses—protecting both people and the environment.
Lifecycle Approach
Integrity begins at design and must continue throughout construction and operation.
- Design phase: define requirements and perform verified calculations.
- Construction phase: inspection and verification ensure compliance.
- Operational phase: periodic review and maintenance preserve reliability.
Our ongoing support enables owners to maintain safety and integrity throughout the full lifecycle of their assets.
Legal and Standards Framework
Asset owners are legally required to prevent leaks and mitigate risks. We help them meet this duty of care by applying recognized standards such as EN 1591-1, ASME VIII, ASME PCC-1, and relevant DIN/EN specifications. Our methodologies align with recognized quality systems and environmental frameworks, ensuring every design step is defensible and documented.
Our Aim
Our goal is to increase awareness among asset owners of the specific risks associated with flanged joints and to guide them in establishing systematic integrity programs during operation.
We promote a culture of prevention, compliance, and technical excellence—helping organizations transition from reactive maintenance to proactive integrity management.
Systematic Risk Management
Flanged joints require specialized technical evaluation and consistent management. Flange Management integrates its services within the PDCA (Plan–Do–Check–Act) methodology to create a structured Risk Management System (RMS) that is coherent, controlled, and continuously improved. This approach ensures that every flange connection is managed, monitored, and maintained with measurable performance indicators.
Target Group
Flange Management serves asset owners, EPC contractors, and operators who demand measurable assurance of flange integrity.
Our findings, calculations, and recommendations provide a clear, practical foundation for achieving leak-free operation and full compliance with legislation and corporate standards.
In essence
Flange Management delivers the engineering certainty behind every joint—linking accurate calculation, verified documentation, and responsible asset management to one goal: Leak-Free Performance.
