2205 duplex stainless steel pipes have excellent mechanical properties and corrosion resistance, as well as good weldability, and are widely used in the oil and gas industry, marine engineering, chemical industry and other industries.
The length of oil and gas pipelines laid by the oil and gas industry using duplex 2205 stainless steel materials has exceeded 850km, most of which are 2205 duplex stainless steel seamless steel pipes (some are also S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); Due to the strong corrosiveness of the natural gas medium transported by the West-East Gas Transmission Project, high-pressure pipelines all use 2205 duplex stainless steel pipes.
