Product description
Stainless Steel Conduit is specified in corrosive applications that exceed the limitations of aluminum, fiberglass, rigid steel, PVC, and PVC-coated conduit. Type 304 UL-listed stainless steel conduit meets and exceeds current requirements for wash down and harsh/corrosive environments. Additionally, it satisfies the strictest mandates for plant cleanliness by various state agencies and hundreds of common regulatory requirements. Similar to our galvanized conduits, Stainless Steel Conduit is available in IMC, EMT, and RMC. Offered as Atkore brand Calbrite.
Interpretation
The contribution analysis indicates that most of the potential impacts occur as a result of raw material supply (A1) with an important contribution coming also from manufacturing (A3). The biggest contributors of of impacts in each stage are respectively supply of stainless steel coil in A1 and usage of electricity and natural gas in A3.
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.
