ASTM A789/A790 Super Duplex Pipes

Silver Tubes is a reliable supplier and exporter of ASTM A789/A790 Super Duplex Pipes. We are engaged in the continuous manufacturing of super duplex pipes in different designations, specifications and custom dimensions. Thus, we are able to fulfill every requirement of our customers. We also supply these super duplex pipes with tolerance limits and machining allowances for multiple usages.

ASTM A789/A790 Super Duplex Pipes overview:
Super duplex pipes are designed for applications where elevated corrosion resistance and strength is required. it has a mixture of molybdenum, nickel and chromium content. This composition results in great resistance to crevice and pitting corrosion attacks. Usage of super duplex pipes should be limited to applications below 316 deg C. However, usage in above temperatures can decrease the corrosion resistance and toughness. These pipes have excellent mechanical properties. Moreover, it has a low weight which makes it easy to use in complex piping applications.

ASTM A789/A790 Super Duplex Pipes characteristics:
These have a higher resistance to chloride stress corrosion cracking
Posses high strength
Higher resistance to crevice and chloride pitting corrosion
Well suited for higher temperature applications
Good local and general corrosion resistance
Having properties of both ferritic and austenitic structure
Great workability and weldability

Tests:
Compression test
Mechanical test
Hardness test
Pitting corrosion test
Intergranular corrosion test
Tensile test
Leakage test

Packaging of ASTM A789/A790 Super Duplex Pipes includes wooden cases, cartons, and pallets. These are also supplied in the big bundles with plastic end cap supports.

One of the types of Duplex stainless steels is the Super Duplex stainless steel, with larger contents of molybdenum, nickel, and chromium and mechanical properties of higher yield and tensile strength. As a result super duplex or 2507 grade stainless steel has improved corrosion resistance properties when compared to other duplex stainless steels.

Super duplex stainless steel grade 2507 or S32760 exhibits better pitting and crevice corrosion resistance, with its PRE being greater than 40 compared to around 35 for Duplex grade 2205, 24 for 316L and 33 for 904L.

Super duplex pipes and tubes are widely used in oil refinery heat exchangers, cargo tanks and pressure vessels, seawater applications, desalination plants, refineries and petrochemical plants.

Super duplex stainless steel have much in common with austenitic and ferritic stainless steels, but they have better resistance than most austenitic grades, more toughness than most ferritic grades and higher strength than most grades of either type. Duplex stainless steels also have the advantage of lower nickel content, making it an attractive option compared to austenitic grades, especially when the cost of nickel is high.
