Product description
The HSS tube and pipe products analyzed in this study are made of mainly carbon steel with a small percentage of alloy elements and paints included. The product has a density of approximately 7,850 kg/m3. Nova Tube’s HSS tube and pipe products are typically produced by cold-forming and welding processes to form round, square, or rectangular shapes with various dimensions and lengths. HSS are typically used in buildings, and other structures.
Interpretation
The LCA results indicate that the steel coil input is the largest contributor to the individual site results and the production-weighted average HSS and pipe products across all impact categories for Ohio facility. For the Canadian facilities, St. Patrick and Baie-d’Urfè, steel coil is the dominant contributor in all categories except for ODP. The HSS and pipe products produced at the Ohio site have a higher GWP footprint (1,802 kgCO2e/MT) than those of Baie-d’Urfè (1,629 kgCO2e/MT) and St. Patrick (1,677 kgCO2e/MT), respectively. At the St. Patrick, Baie-d’Urfè, and Ohio sites, steel inputs represent 91%, 94%, and 98%, respectively, of the total cradle-to-gate GWP footprint. The A1 stage is the highest contributing life cycle stage to GWP, AP, SFP, and ADPfossil for the products produced at St. Patrick. The A1 stage is the highest contributing stage to GWP, AP, EP, SFP, and ADPfossil for the products produced at the Baie-d’Urfè site. The A1 stage is the highest contributing life cycle stage to all LCIA impact categories for the products produced at the Ohio site. The production weighted average HSS and pipe product has a GWP of 1,698 kgCO2e/MT, and is contributed most significantly by the A1 stage, representing 83% - 94% of each LCIA impact category.
The results of the LCIA indicate that the potential environmental impacts for the HSS products are driven by steel coil raw material input. Inbound transport of raw materials (A2) also have a modest contribution at St. Patrick and Baie-d’Urfè sites. Manufacturing stage (A3) was the second major contributor to all impact categories at the Delta, Ohio site.
LCIA results are relative expressions and do not predict impacts on category endpoints, the exceeding of thresholds, safety margins or risks. EPDs are comparable only when they follow the same PCR, functional unit and system boundary. The full EPD (PDF) contains the methodology, scenario assumptions and verification statement.
