2205 Duplex & SUS316Ti Stainless Steel Pipes 3/8" – DIN 17456 |
Chloride Resistance | Desalination Plants & Marine Systems
Manufacturer: JIANGSU CHINA STEEL UNION INDUSTRIAL CO.,LTD
1. Product Introduction
2205 Duplex and SUS316Ti Stainless Steel Pipes (3/8" Diameter) by Jiangsu China Steel Union Industrial Co., Ltd are engineered for extreme chloride-rich environments, including
seawater desalination plants, offshore platforms, and chemical
processing units. Combining 2205 duplex steel (PREN ≥34) and SUS316Ti (titanium-stabilized 316 variant), these pipes deliver unmatched
resistance to pitting, crevice corrosion, and stress corrosion
cracking (SCC) in high-salinity, high-temperature conditions. The
3/8" (10mm) diameter with precision-controlled wall thickness
ensures optimal flow dynamics for reverse osmosis (RO) systems,
brine discharge lines, and coastal cooling circuits. Seamless
manufacturing and DIN 17456 compliance guarantee leak-proof
performance under pressures up to 80 bar.
