SILVER TUBES supply, Stock and export optimum quality Stainless Steel Duplex Pipes & Tubes in various grades and specifications as per international standards with EN 10204 3.1/3.2 Test certifications complying to NACE MR 01 75

Stainless Steel Duplex Pipes & Tubes are a cost effective solution for many applications where the 300 series stainless steels are susceptible to chloride stress corrosion cracking. Stress corrosion cracking occurs when stainless steels are subjected to tensile stress, while in contact with solutions containing chlorides. Increasing temperatures also increase the susceptibility of stainless steels to stress corrosion cracking. The combination of chromium, molybdenum and nitrogen convey the good resistance to chloride pitting and crevice corrosion. This resistance is extremely important for services such as marine environments, brackish water, bleaching operations, closed loop water systems and some food processing applications. The high chromium, molybdenum and nitrogen contents of Stainless Steel Duplex Pipes & Tubes provide corrosion resistance superior to common stainless steels, such as, 316L and 317L in most environments.
