ASTM A790 UNS S32750 ( 1.4410 ) SUPER DUPLEX STAINLESS STEEL SEAMLESS PIPE

 

ASTM A790 UNS S32750 is a Super duplex stainless steel with 25% chromium, 4% molybdenum, and 7% nickel material for seamless and welded pipes in duplex stainless steel alloy for general corrosive service, with particular emphasis on resistance to stress corrosion cracking (SCC) , designed for demanding applications which require exceptional strength and corrosion resistance, such as chemical process, petrochemical, and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity, and a low coefficient of thermal expansion.

 

Super Duplex 2507 Seamless Pipes offers greater corrosion resistance as well as increased strength as compared to the Duplex version, especially because of the presence of additional molybdenum, chromium and nitrogen content. We have Super Duplex S32750 Seamless Pipes which are used in offshore platforms, heat exchangers mechanical and structural components along with other seawater piping and chemical processing industries.

Some of the quality tests carried out by us includes:

Corrosion Test Conducted only when specially requested by the client
Chemical Analysis Test done as per required quality standards
Destructive / Mechanical Testing Tensile | Hardness | Flattening | Flare | Flange
Reverse-bend and Re. flat tests Carried out in full compliance with relevant standards & ASTM A-450 and A-530 norms, which ensures trouble-free expansion, welding & use at customers end
Eddy Current Testing Done to detect homogeneities in subsurface by using Digital Flaw-mark Testing System
Hydrostatic Testing 100% Hydrostatic Testing carried out according to ASTM-A 450 norms for checking tube leakage, and biggest pressure we can support 20Mpa/7s .
Air Under Pressure Test To check any evidence of air leakage
Visual Inspection After passivation, every single length of tubes & pipes is subjected to thorough visual inspection by trained staff for detecting surface flaws & other imperfections

Supplementary Testing: Apart from the above mentioned tests, we also carry out on the manufactured products supplementary testing. The tests conducted under this include:
