2205 Stainless steel Pipe/Tube-Stainless steel Pipe/Tube-Shandong Aofeng Metal Material Co.,Ltd-

2205 Stainless steel pipe Widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial transport pipelines and mechanical structural components. In addition, when the bending and torsional strength are the same, the weight is lighter, so it is also widely used in manufacturing mechanical parts and engineering structures. It is also often used in the production of conventional weapons, barrels, shells and so on

About 2205 duplex seamless stainless steel tube

2205 duplex stainless steel pipes have excellent mechanical properties, corrosion resistance and weldability. They are widely used in petroleum and natural gas industry, marine engineering, chemical industry and other industries. At present, the length of oil and gas pipelines laid with duplex stainless steel materials in petroleum and natural gas industry has exceeded 850Km, and most of them are 2205 duplex stainless steel seamless pipes (some are S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes). Because of the strong corrosiveness of natural gas medium, 2205 duplex stainless steel materials are used in high-pressure pipelines of West-East Gas Transmission Project.
