Material Property

Biphase structure: ASTM A790 duplex steel pipe consists of approximately equal amounts of austenite and ferrite phases. This unique two-phase structure gives it excellent comprehensive properties.

Corrosion resistance: It has excellent corrosion resistance to chloride, sulfuric acid, acetic acid and other media. Especially in high temperature, high pressure or high concentration corrosive media performance is particularly outstanding.

Mechanical properties: high yield strength and tensile strength, while maintaining good plasticity and toughness. Therefore, this steel pipe is suitable for working under complex stress conditions.

Thermal stability: It can maintain stable mechanical properties and corrosion resistance under high temperature conditions.

Application Field of ASTM A790 Duplex Steel Pipe

Oil and gas industry: Used for the transportation of corrosive media in submarine pipelines, oil and gas field gathering pipelines, refineries and chemical plants.

Chemical industry: dealing with various corrosive chemicals, such as sulfuric acid, hydrochloric acid, phosphoric acid, etc.

Seawater desalination: As a seawater pipeline in the seawater desalination system, it is subjected to corrosion from high-salinity seawater.

Pulp and paper: Handling corrosive media such as chlorine-containing bleach.
