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.
