Design

Eiffage Métal designs every type of gas flare system based on gas composition and flow, including guy-wired, derrick and self-supporting flare stacks, thermal oxidizers (with equipment), flame detection, thermocouples, ignition panels, flare tips, and automation.
- From gas composition and flow: gas analysis, combustion, sizing, radiation, emissions, noise.
- Mapping: PID, functional analysis and GRAFCET
- Design and engineering department: comprehensive plans and three-dimensional flare modelling

Manufacturing

Manufacturing
The flare systems are built in our Cuincy workshops to comply with the processes set up by a welding engineer (welding specifications, QMOS, DMOS, etc.) and specific monitoring methods (radiography, bleeding, and PMI tests). Special attention is paid to the choice of material:
- Carbon steel (P265GH, API5L)
- Stainless steel (310S, 304L, 316L)
- Corten (weathered) steel (marine environment)

Assembly

Assembly
All facilities and equipment are assembled by our teams of experts.
- Testing assembly in our Cuincy workshops.
- On-site assembly. Our service includes transport, maintenance, connections, pipework, electricity, and automation.
- Commissioning. We adjust facility settings (fluids, electricity, and automated functions) and handle on-site staff training.

Maintenance

Maintenance
Stringent inspections of our facilities allow us to identify flare parts in need of repair or replacement. Maintenance work is carried out during unit shutdowns.
- Expertise: the entire flare system (flame detection, ignition unit and pilot, stack, guy wire inspection and lubrication, verticality tests etc.) is monitored during scheduled shutdowns, in order to establish a forecast report of work to be carried out. This expertise can also be carried out using a drone (our teams are trained in steering) if the flare is to remain in operation.
- Revamping: the flare systems undergo repair and upgrading work in our Cuincy workshops, including testing, repairs, spare part replacement and refurbishing.
