Hot bending is a crucial stage in the prefabrication and assembly of piping. It is used in the chemical and petrochemical, offshore and subsea industries, as well as in thermal and nuclear power plants.
Fives has developed its expertise in hot bending thanks to its thorough understanding of processes covering all aspects of carbon steel, alloys and stainless steel.
We continually improve our performance and technical abilities. Fives is now recognized as a highly qualified partner and has over one hundred bending procedure qualification records.
In addition to induction bending, our teams’ technical expertise enables us to offer different services:
- Supply of parent tubes
- Blasting and polishing
- Stripping and passivation
- Thermal treatments (overhardening, normalization and tempering)
- Chamfering, drilling
