Corrosion resistant stainless steel pipes (such as 316L and 304 materials) have the following characteristics:
corrosion resistance
Containing elements such as chromium (Cr), nickel (Ni), and molybdenum (Mo), a dense passivation film is formed on the surface, which can resist corrosive media such as acid, alkali, and salt. 316L performs well in chloride and high temperature environments (below 1600 ° F) due to its molybdenum (2-3%) and nickel (12-15%) content; 304 stainless steel contains 18% -20% chromium and 8.25% -10.5% nickel, suitable for scenarios such as nitric acid and organic acids.
mechanical properties
316L tensile strength ≥ 520N/mm ², elongation ≥ 40%, density 7.93g/cm ³, can maintain stability at high temperatures; 304 tensile strength ≥ 520N/mm ², elongation ≥ 40%, same density, high temperature resistance up to 1000-1200 ℃.
Application scenarios
Suitable for chemical equipment, petrochemical pipelines, food production systems, and marine environments. For example, 316L is used in pulp and dyeing equipment, while 304 is commonly used in food processing equipment.
Corrosion resistant stainless steel pipes play a crucial role in multiple fields due to their excellent corrosion resistance and mechanical properties.
Main applications
Chemical and energy fields
Corrosion resistant stainless steel pipes (such as 1.4659 duplex stainless steel) perform well in environments containing chloride ions due to the presence of molybdenum, nitrogen, and other elements. They are suitable for seawater desalination equipment, oil and gas pipelines, and chemical storage tanks. Its yield strength is about 50% higher than that of ordinary 304 stainless steel, and it can withstand high pressure and complex structural processing requirements.
Architecture and Industrial Applications
1. High pressure fluid transportation: Corrosion resistant steel pipes replace traditional pipes in building water supply systems, withstand high pressure without easy leakage, and comply with standards such as GB/T12771.
2. Suitable for extreme environments: 316L stainless steel pipes can be used intermittently below 1600 ° F and are suitable for high temperature and high corrosion scenarios such as pulp equipment and dyeing workshops.
3. Health and safety guarantee: The inner wall is smooth and not easy to scale, which meets the safety standards for drinking water and is widely used in food processing and medical device delivery systems.
Ocean and Food Industry
Corrosion resistant steel pipes containing nickel and chromium form a dense oxide film in marine environments, effectively resisting salt corrosion and extending equipment service life. For example, 304 and 316 stainless steel pipes are commonly used in coastal facilities and food processing production lines
