Description
Gnee Steel (Tianjin) Co., Ltd. is one of the most professional manufacturers and suppliers of duplex 2205 stainless steel seamless pipe in China. With abundant experience, we warmly welcome you to wholesale customized duplex 2205 stainless steel seamless pipe from our factory. For price consultation, contact us.
2205 duplex stainless steel cold drawn tube is an alloy composed of ferrite and austenite, with ferrite accounting for 45~55% and austenite accounting for 55~45%.
The yield strength of 2205 duplex stainless steel seamless tube is more than double that of ordinary austenitic stainless steel, and the tensile strength is between 600~800MPa. Its corrosion resistance is better than that of ordinary 316L austenitic stainless steel. It has good resistance to pitting corrosion, crevice corrosion and stress corrosion cracking.

Application fields of duplex 2205 stainless steel pipes
Petroleum and natural gas industry: used for laying oil and gas pipelines, especially in highly corrosive media.
Chemical industry: used to manufacture corrosion-resistant equipment parts.
Marine engineering: used to manufacture components of offshore platforms and ships.
2205 duplex stainless steel pipe case
The length of oil and gas pipelines laid by duplex stainless steel materials in the petroleum and natural gas industry 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 are all made of 2205 duplex stainless steel.
