Duplex 2205 High Pressure Pipe 2"X10ft, ASTM A790, Acid-Resistant,
Chemical Processing
Duplex 2205 High-Pressure Pipes (2"x10ft) by Jiangsu China Steel Union Industrial Co., Ltd are engineered for aggressive chemical and petrochemical
environments requiring exceptional corrosion resistance and
structural strength. Compliant with ASTM A790, these seamless duplex stainless steel pipes combine austenitic
and ferritic microstructures, delivering double the yield strength
of standard 316L while resisting pitting, stress corrosion cracking
(SCC), and sulfuric/chloride-induced degradation. The 2" diameter
and 10ft length optimize high-pressure fluid transport in acid
processing, refinery pipelines, and heat exchangers. Ideal for
temperatures up to 300°C, these pipes maintain integrity in acidic media (e.g., H₂SO₄, HCl)
and high-salinity conditions, making them indispensable for
chemical reactors and offshore platforms.
