A certified partner

Fives' Piping Solutions offer has certifications and standards qualifications (STAMP U, ADHP and SELO) for all types of welds: up to 40 mm for TIG and manual MIG and up to 90 mm for automatic MIG. With the equipment Fives has in its shops, it can guarantee customers top-quality high-tech products and very quick response times.

Fives and its Piping Solutions business line have worked together on nuclear contracts for new EPRs and next-generation thermal plants to provide:

the primary piping systems for EPR Olkiluoto 3, Flamanville 3, Taishan 1 and 2 for Areva,

piping systems and onsite installation of the test loop for the Areva JSPM EPR primary motor-driven pump units,

Inconel 82 buttering and butt-joining for containment openings in the EPR Flamanville 3 reactor building

high-pressure piping systems for next-generation thermal plants.

In an ongoing effort to maintain our employees' qualifications and skills, the business line has two training centers in  manual and automated welding at our facilities in Nancy  and Cherbourg,  France. 

The business line also has an industrial site in Nancy, a division specifically focused on development. This division features a modular floor design that can be moved around to simulate real-life environments and machinery footprints.

Fives’ Piping Solutions business line develops innovative welding processes for its customers that meet their special requirements. Some recent developments by our R&D teams:

  • automatic welding for valves located in high-radiation zones,
  • repairing blades in primary heat pumps,
  • TIG orbital narrow gap welding 

Fives and its Piping Solutions business line have 160 employees certified in welding  who can work on over 2,000 Welding Process Specifications (WPS)  and qualify for the standard international industrial codes (EN, ISO, RCC-M, RSE-M, ASME, AD-MERKBLATT, etc.). 

These WPSs cover a wide range of metal alloy grades: all low-alloy steels, high-alloy steels, P91 and P92 martensitic steels for thermal plants, ferrite/austenitic/austenitic-ferrite (dual-phase grade) stainless steels, nickel alloys, aluminum alloys, copper alloys and titanium alloys.

Extensive experience in high-pressure piping for extreme temperatures

Fives' Piping Solutions business line can build several types of high-pressure high-temperature piping systems for even the most challenging projects.

For example, it created a complete circuit for the Maritza project, loop pipes, custom-built bends and piping systems at customer sites in Blénod-les-Pont-à-Mousson, West Burton, Cardiff, Pembroke and Flamanville.
