Excellent Corrosion Resistance

Engineered for environments where corrosion is a concern, these duplex stainless steel pipes excel in pitting and crevice corrosion resistance. The microstructure combines the benefits of both ferritic and austenitic grades, allowing them to withstand harsh chemicals and demanding offshore, marine, and petrochemical conditions.

Flexible Sizing and Customization

With diameters ranging from 6 mm to 610 mm and lengths up to 12 meters (or custom cut to size), Duplex S31803-S32205 Pipes offer extensive flexibility for diverse industrial requirements. Pipe ends are available in plain, beveled, or threaded types, making integration seamless regardless of your piping system's needs.

Strict Quality Assurance

Each pipe undergoes 100% radiography, hydrostatic, and visual inspection to ensure top performance and adherence to standards. Markings indicating grade, size, and heat number guarantee traceability, while packaging options like plastic caps, bundles, or wooden cases protect your order during transit.

FAQ's of Duplex S31803-S32205 Pipe:

Q: How are Duplex S31803-S32205 Pipes manufactured and tested for quality?

A: These pipes are produced via both seamless and welded processes, followed by solution annealing at 1020-1100C. Every pipe is rigorously tested using 100% radiography, hydrostatic testing, and visual inspections, ensuring compliance with ASTM A790 / ASME SA790 standards.

Q: What are the end connection options available, and how do they benefit the installation process?

A: Pipes are available with plain ends, beveled ends, or threaded ends (NPT/BSP), allowing for easy integration with butt weld, threaded, or socket weld connections. This versatility makes installation efficient in diverse industrial systems.

Q: Where can these duplex stainless steel pipes be used?

A: They are widely used in structural, chemical processing, oil & gas, petrochemical, offshore, marine, and water treatment applications, thanks to their excellent strength, rigidity, and corrosion resistance.

Q: What is the corrosion resistance capability of Duplex S31803-S32205 Pipe?

A: They exhibit excellent pitting and crevice corrosion resistance, especially in aggressive environments with chloride and other harsh chemicals. This makes them ideal for critical service conditions.

Q: When is a specific end type (plain, beveled, or threaded) recommended?

A: Plain or beveled ends are typically chosen for welding applications, supporting butt-welded or socket-welded joints. Threaded ends (NPT/BSP) are best for systems requiring easy assembly or disassembly, such as maintenance-intensive setups.

Q: What is the minimum order quantity and how are the pipes packaged?

A: Minimum order quantity is just 1 meter, and pipes are packaged using plastic caps, bundled, or securely placed in wooden cases to prevent damage during shipping and handling.

Q: What are the key mechanical properties and benefits of using this duplex grade?

A: With a yield strength of at least 450 MPa, tensile strength of 620 MPa min, and 25% minimum elongation, the pipes offer high durability and rigidity, making them suitable for high-pressure and temperature applications ranging from -50C to +300C.
