Upstream Process | External raw material supply
Upstream processes cover all operations of Vallourec’s suppliers for the procurement of raw materials and energy carriers that are then used in the company’s operations, such as:
- Steel billets, bars, ingots and tubes;
- Ferroalloys;
- Scrap;
- Other raw materials feeding the pelletizing plant, blast furnaces and steel mills, such as steel scrap, pig iron, coke, coal, lime, limestone, graphite, etc. – all supplied for Youngstown (USA) and Jeceaba (Brazil) integrated sites with steel mills.
The environmental impacts of raw materials and energy carriers are assessed from cradle to Vallourec’s gate, and cover in particular:
- Extraction and/or mining and/or collection, sorting and
processing; - Process emissions resulting from the purchase of pellets,
pig iron, steel and steel products; - Land management and wood carbonization for the production
of biomass charcoal, including CH4 emissions associated with
the purchase of biogenic pig iron; - Transportation from the supplier’s site to Vallourec’s gate.
The environmental impacts of the construction of power plants, such as the manufacture of solar panels or nuclear power plants that supply electricity to Vallourec is accounted for. Transportation and distribution losses are also included, as well as the upstream transformation of fossil fuels consumed by Vallourec.
Upstream Process | Internal steel making
Steel making can also be integrated as part of Vallourec’s operations, in the steel mills of Jeceaba (Brazil) or Youngstown (USA). Industrial processes include:
- Internal raw material manufacturing, such as iron ore extraction and processing, eucalyptus forest management, charcoal production and ore pelletization;
- Land management and wood carbonization for the production of biomass charcoal (in Brazil’s Florestal Eucalyptus forest) with CH4 emissions from charcoal carbonization kilns, and zero CH4 emissions from Vallourec’s innovative Carboval process;
- Process emissions related to chemical reactions in the pelletizing plant, blast furnace and electric arc furnaces;
- Internal transportation of raw materials and intermediate products (including iron ore, pellets and charcoal) to the pelletizing unit, blast furnaces and steel mills.
Core Process | Tube manufacturing
Tube making represents the last part of Vallourec’s process, which consists of:
- Rolling mills, transforming steel billets into hollow tubes;
- Heat treatment units, so that seamless steel products meet specification criteria;
- Finishing lines, with various applications such as threading, quality testing, painting, or coupling tube ends with plugs;
- Transportation of semi-finished tubes from one Vallourec mill to another;
- Electricity production, either through on-site solar panels, or diesel generators;
- Internal recovery, or treatment of the waste generated
by the manufacturing process; - Water treatment and recirculation, as the core process requires cooling and quenching.
