FAQ (Frequently Asked Questions)

What are Super Duplex Steel Pipes?

Super Duplex Steel Pipes are a type of stainless steel piping made from an alloy containing high levels of chromium, nickel, molybdenum, and nitrogen. They belong to the duplex stainless steel family, known for their exceptional corrosion resistance and high strength. Super Duplex Steel Pipes offer superior performance in harsh environments such as offshore oil and gas platforms, chemical processing plants, and desalination facilities, where corrosion resistance and durability are critical. They are characterized by their resistance to pitting and crevice corrosion, as well as their ability to withstand high temperatures and pressures. These pipes are widely used in various industries where reliability and longevity are paramount.

How are Super Duplex Steel Pipes Sized?

Super Duplex Steel Pipes are sized based on their nominal diameter (DN) or nominal pipe size (NPS), which represents the approximate inside diameter of the pipe. The sizing also considers factors such as wall thickness, pressure rating, and applicable standards (e.g., ASTM, ASME). Common sizing standards include ANSI/ASME B36.19 for seamless pipes and ANSI/ASME B36.10 for welded pipes. Pipe sizes typically range from 1/8 inch to 48 inches or larger, with various schedules (thickness) available to accommodate different pressure ratings. Proper sizing is essential to ensure the pipes meet the requirements of the intended application in terms of fluid flow, pressure, and structural integrity.

Are Super Duplex Steel Pipes recyclable?

Yes, Super Duplex Steel Pipes are recyclable. Like other stainless steels, Super Duplex Steel contains valuable materials such as chromium, nickel, and molybdenum, which can be reclaimed and reused in the production of new stainless steel products through recycling processes. Recycling Super Duplex Steel Pipes helps conserve natural resources, reduce energy consumption, and minimize environmental impact compared to producing new steel from raw materials. Additionally, stainless steel is highly durable and can be recycled repeatedly without losing its properties, making it a sustainable choice for various applications.
