The 316L stainless steel pipe combines the properties of ferrite and austenite, and has excellent resistance to chloride stress and corrosion cracking. 2205 is a duplex stainless steel composed of 21% chromium, 2.5% and 4.5% bromine-nitrogen alloy. Its yield strength is twice that of austenitic stainless steel.

This characteristic enables designers to reduce the weight when designing products, making this alloy more advantageous than 316 and 317L. Due to the high content of chromium and molybdenum in this steel, it has excellent resistance to pitting corrosion and uniform corrosion. The dual-phase structure ensures that this steel has high resistance to stress corrosion cracking and high mechanical strength. The 316L stainless steel pipe material has excellent mechanical properties and corrosion resistance, as well as good weldability. It is widely used in industries such as the petroleum and natural gas industry, marine engineering, and chemical industry.

At present, the petroleum and natural gas industries have laid oil and gas pipelines using duplex stainless steel materials with a length exceeding 850 kilometers. The majority of these pipelines are seamless 316L stainless steel pipes (with some also being S31803 duplex stainless steel pipes and 2507 duplex stainless steel pipes); for the West-East Gas Transmission Project, due to the strong corrosiveness of the natural gas medium being transported, all the high-pressure pipelines are made of 316L stainless steel materials.

The applications of 316L stainless steel pipes include the following aspects: neutral chloride environments, the oil refining industry, the petrochemical and chemical industries, delivery pipelines for chemical industries, the oil and natural gas industries, the pulp and paper industries, the fertilizer industry, the urea industry, the phosphate fertilizer industry, marine environments, the energy and environmental protection industries, the light industry and food industries, food and pharmaceutical industries, and high-strength structural components.
