- for large-capacity steam-cracking furnaces
- reforming furnaces
- and related components for the cracking furnaces for olefin production
The cast products manufactured by Manoir Industries, using metal processes, are made to reproduce, after cooling, a geometry with a metallographic structure that meets its customers’requirements.
This manufacturing process is used for the petrochemical, nuclear, hydraulic, steel, defence and industrial markets. The products created include the following:
- Accessories for large-capacity steam-cracking and reforming furnaces, and related components for the cracking furnaces for olefin production;
- Nuclear cast components for primary and secondary circuits. At least one cast component has been installed in all French nuclear power plants, but they have also been installed around the world, including in China, Belgium, the United Kingdom, etc;
- Francis-type wheels of different sizes in martensitic stainless steel are manufactured and delivered, machined and ready to be assembled, for markets such as hydraulics and nuclear;
- Steel industry: some examples of various sizes and complex morphologies cast components manufactured in sand casting or by centrifugation: rolls for strip mills, furnace rolls, conveyor rolls for annealing or galvanizing lines, tubular bundles and radiant tubes;
- Railways: cast components developed in proprietary alloys for railway crossings;
- Defense: Manoir Industries develops and controls in-house cast components from some kgs up to 10 tonnes for delivery to France and abroad.
