The Welding Of Duplex Stainless Steel Pipe In Offshore Platform | NEW 1st Unlock
The welding of duplex stainless steel pipe in offshore platform requires specialized knowledge of metallurgical behavior and precise process control.
The welding of duplex stainless steel pipe in offshore platform applications requires specialized knowledge of metallurgical behavior and precise process control. Key recommendations include:
For S31803 duplex pipe: Maintain heat input below 1.5 kJ/mm and use nitrogen-enhanced shielding gases
For 2507 super duplex pipe applications: Implement strict interpass temperature control and solution anneal critical welds
Always verify phase balance through Feritscope measurements and corrosion testing
As offshore operations move into deeper waters and more aggressive environments, the proper welding of duplex stainless steels will remain critical for ensuring long-term structural integrity and safety.
