Duplex Steel Pipes are high-strength stainless steel pipes designed for excellent
corrosion
resistance, superior mechanical properties, and outstanding resistance to stress
corrosion
cracking. With a balanced austenitic–ferritic microstructure, these pipes perform
reliably in
high-pressure and highly corrosive service environments.
Duplex Steel Pipes are manufactured in seamless and welded forms and are extensively
used in
oil & gas, offshore platforms, chemical processing plants, marine systems, power
generation,
and pressure piping applications where durability and long service life are
essential.
Duplex Steel Pipes are available in standard duplex grades to suit diverse operating
conditions.
The most commonly supplied grades include
Duplex S31803 (UNS S31803) and
Duplex S32205 (UNS S32205), known for their excellent resistance to
pitting and
crevice corrosion, high yield strength, and superior weldability.
