Industrial piping and flares

Piping, industrial flares, thermal oxidizers: expertise for over 30 years

Eiffage Métal designs, manufactures, assembles and maintains industrial flare systems and thermal oxidizers. The company offers flare systems for the onshore/offshore oil & gas, gas storage, petrochemicals, water treatment (biogas), biomass, rail tank degassing, gas combustion units for LNG-powered ships, and mobile flares and thermal oxidizers sectors.

Eiffage Métal is also active in industrial piping, covering the entire production lifecycle: from detailed design, through manufacturing, to installation and commissioning, including all safety checks. We design piping systems for a wide range of sectors, including the petrochemical, pharmaceutical, food, energy and airport industries. These handle the transport of fluids such as process fluids, steam, water, gas, compressed air, nitrogen and more.

Our knowledge and experience help guarantee the performance of industrial installations, optimize production processes and ensure compliance with quality and safety standards.

Neoflare, the new range of compact hidden-flame flares

Protected flame = safety
Optimized energy performance = efficient combustion
Simplified maintenance = increased durability, reduced costs, smaller footprint

A patented innovation from Eiffage Métal, designed and manufactured in France at our Cuincy production facility.

Our expertise

< class="name">Design
Eiffage Métal designs, from the composition and flow of the gases, any system of torches (guyed torch, torch on derrick, stable auto torch, thermal oxidizers – with their equipment – flame detection, thermocouples, ignition station, torch nose, automation, etc.).

From gas composition and flow: analysis, combustion, sizing, radiation, releases, noise

Schematization: PID, functional analysis and Grafcet.

Design office: stability calculations, realization of the overall plans and modeling of the torch.
Manufacturing
The torch systems are manufactured in our Cuincy workshops, following procedures set up by a welding engineer (welding books, QMOS, DMOS, etc.) and defined control means (radiography, penetrant, PMI). Particular attention is paid to the choice of materials:

Carbon steel (P265GH, API5L)

Stainless steel (310S, 304L, 316L)

Corten steel (marine environment)
Assembly
Our teams of experts carry out the assembly work of the equipment.

Blank assembly in our workshop in Cuincy.

Assembly on site: transport, handling, connections, piping, electricity and automation.

Commissioning: adjustments related to installations (fluids, electricity and automation) and training of staff on site.
maintenance
We carry out strict inspections of the facilities to repair or replace one or more elements of the torch. This work is carried out during unit shutdowns.

Expertise: during scheduled shutdowns, we control the entire torch system (flame detection, ignition station and pilot, summer, guying systems, verticality, etc.) in order to establish a provisional report of the work to be carried out. It is also possible to conduct this expertise using a drone (our teams are trained to fly) if the torch must remain in operation.
Revamping: restoration and modification of torch systems in our workshop in Cuincy (checks, repairs, change of spare parts, reconditioning...).
