S32205 Duplex Stainless Pipe
To ensure the performance of S32205 Duplex Stainless Pipe, the manufacturing process must control several key parameters:
Chemical Composition: Strict adherence to chemical composition limits as per ASTM A790 or A928 standards to ensure mechanical properties and corrosion resistance .
Welding: Use of appropriate welding methods such as TIG or laser beam welding with low heat input to prevent phase transformation and maintain duplex structure .
Heat Treatment: Solution annealing at temperatures around 1050°C followed by rapid cooling, often water quenching, to restore ductility and corrosion resistance .
Non-Destructive Testing (NDT): Ultrasonic or radiographic testing to ensure no internal defects are present in the welds .
Mechanical Testing: Tensile and impact tests to verify the strength and toughness of the material .
Corrosion Resistance Testing: Tests like pitting resistance equivalent number (PREN) calculations and ferric sulfate tests to ensure resistance to pitting and stress corrosion cracking .
Cleaning: Thorough cleaning after welding to remove any contaminants that may lead to corrosion .
