2205 Seamless steel pipe Features
2205 duplex stainless steel pipe is defined as a stainless steel whose ferrite phase and austenite phases in its solid-quenched structure are half and half, referred to as 2205 stainless steel pipe, also called 2205 duplex steel pipe. The actual phase ratio is that ferrite accounts for 45~55%, and the corresponding austenite accounts for 55~45%. The excellent performance of 2205 duplex stainless steel is ensured by an appropriate ratio of two-phase structure.2205 duplex stainless steel pipe has excellent mechanical properties, corrosion resistance, and good weldability, and has a wide range of uses in the oil and gas industry, marine engineering, chemical industry and other industries. The length of the oil and gas pipelines laid by duplex stainless steel in the oil and natural gas industry has exceeded 850Km, most of which are 2205 duplex stainless steel seamless steel pipes (some of them are S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); West-East Gas Pipeline Due to the strong corrosiveness of the natural gas medium in the project, the high-pressure pipelines are all made of 2205 duplex stainless steel.
