Clad materials combine corrosive and/or wear resistance properties of corrosion resistant alloys (CRA) with various other metals adding safety and protection from harsh chemicals or environments. We’ll look at the similarities and differences of cladding 316 stainless steel, Inconel 625, and Stellite alloys, three of the most common alloys used today.
DNV L1 and DNV L2 are classifications used by Det Norske Veritas Germanischer Lloyd (DNV), a global quality assurance and risk management company, to categorize spools for subsea oil and gas pipelines. We’ve broken out a few of the main differences when comparing DNV L1 to DNV L2.
DNV is recognized as the first classification society in the maritime industry and offers certification assurances to the quality and design reliability of specific products. You might be asking, what exactly are DNV assurance certifications, and why is it important?
