SA 182 SS 316/316L ASME B16.47 Series B 30″ 150# Weld Neck Flanges
316/316L stainless steel flanges have excellent corrosion resistance, particularly in environments with chloride ions, acids, and bases, making them ideal for marine and chemical environments.
High Quality 182 SS 316/316L ASME B16.47 Series B 30″ 150# Weld Neck Flange
SSM provides the SA 182 SS 316/316L ASME B16.47 Series B 30″ 150# Weld Neck Flange, which is made of 316 or 316L stainless steel and complies with the ASME B16.47 Series B standard. This flange is designed for large-diameter piping and medium-pressure applications (150 lbs). Here are the detailed specifications:
- Flange Standard: ASME B16.47 Series B
Series B flanges have smaller bolt circles and bolt diameters compared to Series A flanges, making them more compact. - Nominal Pipe Size (NPS): 30 inches
- Pressure Rating: 150# (suitable for medium-pressure applications)
- Type: Weld Neck Flange (provides a smooth transition from the flange to the pipe, enhancing strength and reducing stress concentration)
Material: SA 182 SS 316/316L
The dual-grade SS 316/316L stainless steel is a material whose chemical composition and mechanical properties meet the standards of both SS 316 and SS 316L, thus allowing it to satisfy the requirements of both grades.
In other words, dual-grade SS 316/316L stainless steel exhibits the characteristics of both SS 316 and SS 316L depending on the specific application needs.
Applications
- Chemical Processing: 316/316L stainless steel flanges offer excellent corrosion resistance, especially in environments dealing with chloride ions or acidic media, widely used in chemical equipment and piping systems.
- Marine Engineering: 316/316L stainless steel flanges perform excellently in seawater and high-humidity environments, making them suitable for shipbuilding, offshore structures, and seawater treatment equipment.
- Oil and Gas: 316/316L flanges are used in oil and gas pipelines and refinery equipment, suitable for high-temperature, high-pressure, and corrosive media environments.
- Food and Pharmaceutical Industries: Due to their excellent corrosion resistance and sanitary properties, 316/316L stainless steel flanges are commonly used in food processing equipment and pharmaceutical industries.
Advantages and Disadvantages
316/316L stainless steel flanges have excellent corrosion resistance, particularly in environments with chloride ions, acids, and bases, making them ideal for marine and chemical environments. Additionally, 316/316L stainless steel retains good mechanical properties in high-temperature environments, making them suitable for high-temperature conditions. The lower carbon content of 316L improves weldability, reducing carbide precipitation during welding and enhancing the corrosion resistance of the welded area. It is also suitable for industries requiring high sanitary standards, such as food and pharmaceuticals.
However, the manufacturing cost of 316/316L stainless steel is relatively high, and despite its excellent corrosion resistance, pitting or crevice corrosion may still occur in environments with high chloride concentrations.
