At Duplex Steel & Alloys, we specialize in Duplex
Stainless Steel Pipes designed to deliver exceptional strength, durability,
and corrosion resistance. Made with a balanced composition of Chromium
(22-23%), Molybdenum (3-3.5%), and Nitrogen (0.14-0.2%), these pipes are
ideal for challenging applications in industries like oil and gas, marine
engineering, chemical processing, and construction. Their unique
metallurgical properties make them highly resistant to pitting and crevice
corrosion while offering superior mechanical strength and reliability.
The high Chromium content provides outstanding
resistance to corrosion, particularly in environments rich in chlorides,
such as seawater. Molybdenum further strengthens the pipes against
aggressive chemical environments, while Nitrogen enhances tensile strength
and microstructural stability, ensuring long-lasting performance under
stress. These properties make our Duplex Steel Pipes the preferred choice
for durable applications, such as subsea pipelines, pressure vessels, and
chemical reactors.
Mechanical Strength for Reliable Performance
Duplex Steel Pipes excel due to their exceptional mechanical
properties, making them reliable in demanding conditions. With a tensile strength of
≥620 MPa, these pipes can withstand significant forces without failure, which is
essential for high-pressure systems like pipelines and boilers. The yield strength of
≥450 MPa supports heavy loads, ensuring structural integrity in construction and
equipment applications. An elongation of ≥25% ensures ductility, allowing the material
to resist cracking under stress, which is critical for industries like shipbuilding and
aerospace. These properties make the pipes versatile for environments involving extreme
pressures and temperatures.
International Standards for Quality Assurance
Our DS Pipes are manufactured in strict compliance with global
quality standards. They meet the requirements of ASTM A789 and ASTM A790, ensuring
suitability for both seamless and welded pipes. Compliance with EN 10088 guarantees
material consistency and mechanical reliability, while ISO 9001 certification reflects
our commitment to quality management. Furthermore, our products adhere to ASME and PED
(Pressure Equipment Directive) certifications, which are essential for safety and
reliability in pressure-related applications. These accreditations establish Duplex
Steel & Alloys as a trusted supplier of premium stainless steel pipes for industries
worldwide.
Testing for Excellence
Every Duplex Steel Pipe undergoes rigorous testing to ensure
performance, safety, and durability. Positive Material Identification (PMI) verifies the
chemical composition, ensuring the pipes conform to Duplex grade standards. This is
crucial in chemical processing and power generation industries, where material integrity
directly impacts operational safety.
Hydrostatic testing evaluates the pipes’ pressure-handling
capabilities, ensuring they can operate without leaks under high-pressure conditions.
This makes them ideal for pipelines, tanks, and pressure vessels. Radiographic testing
is conducted for duplex steel welded pipes to detect internal defects such as voids or
cracks, ensuring structural and weld integrity. These tests underscore our commitment to
delivering flawless, high-performing products.
Applications Across Industries
Duplex Steel Pipes are versatile, meeting the needs of diverse
industries. In the oil and gas sector, they are ideal for handling corrosive substances
like H2S and chlorides, making them indispensable for subsea pipelines and offshore
platforms. In chemical processing, their resistance to acids and alkalis ensures
long-term performance in reactors, heat exchangers, and storage tanks.
In shipbuilding, their high resistance to seawater corrosion makes
them perfect for hulls, ballast systems, and propulsion components. In construction,
their high load-bearing capacity and long-lasting durability make them reliable for
critical infrastructure. These pipes also perform exceptionally well in power
generation, where their strength and heat resistance are crucial for turbines and
boilers.
Grades Comparison: S31803 vs. 32205
Both S31803 and 32205 are widely used duplex grades. While duplex
steel S31803 pipes offer excellent corrosion resistance and strength for general
applications, duplex steel 32205 pipes have slightly higher nitrogen content , enhancing
their resistance to more aggressive environments like those in offshore platforms or
chemical plants. With both grades available, Duplex Steel & Alloys can help you select
the best option for your specific requirements.
Logistics and Documentation
We ensure smooth delivery and complete documentation for every order. Each shipment includes a Material Test Certificate (MTC) to verify compliance with international standards, dimensional reports, and packing lists for accurate handling and installation.
