ASTM A790 S31803 Duplex Steel Seamless Pipe
ASTM A790 S31803 is a specification for seamless duplex steel
pipes. Duplex steel is a type of stainless steel that contains both
austenitic and ferritic microstructures, providing excellent
strength and corrosion resistance.
Seamless pipes are manufactured without any welding seams, which
makes them more reliable and suitable for high-pressure and
high-temperature applications.
These pipes are commonly used in industries such as oil and gas,
chemical processing, and marine engineering. They are known for
their superior performance in harsh environments and are highly
resistant to corrosion, pitting, and cracking.
