Duplex Stainless Steel Pipe

Duplex Stainless Steel Pipe

Duplex stainless steelpipe generally consists of two phases of steel, including ferrite andaustenite. Furthermore, the steel composed of ferrite and martensite refers toduplex steel. In comparison with austenitic stainless steel, our productpossesses several remarkable advantages listed as follows.

Advantages

1. This duplex stainless steel pipe features more than twice the yieldstrength than conventional austenitic stainless. Also, it has enough ductilityand toughness to meet the molding requirement. When used for the manufacture ofstorage tank or pressure vessel, our type has thinner wall thickness thanordinary austenitic type by reduction of 30% to 50%, which is beneficial toreduce costs.

2. Even containing the lowest alloy content, our product can stilldemonstrate better ability of stress corrosion cracking resistance thanconventional austenitic stainless especially in the environment of the chlorineions.

3. With exceedingly good corrosion resistance, our super duplex stainless steelpipe can substitute for high alloy austenitic stainless when used in somemedium like ethylic acid and formic acid etc. Also, our product can providebetter resistance to localized corrosion, abrasion and corrosion fatigue thanaustenitic type product.

4. Due to the lower coefficient of linear expansion, our product is suitablefor the connection with carbon steel, which shows great engineeringsignificance for producing composite board or lining etc.

5. Regardless of the dynamic loading or static loading conditions, this productowns stronger energy absorption capacity than the austenitic stainless steeltube, which possesses actual application value to deal with unexpectedincidents such as collisions, explosions and so on.
