S32750 Super Duplex Steel Blind Flanges are pipeline connectors that possess exceptional mechanical strength, corrosion resistance, and wear resistance. They are constructed using S32750 super duplex stainless steel, a material renowned for its ability to withstand extreme environments. These flanges feature a flat blind plate that is utilized for pipeline blocking purposes. They can control fluid flow by obstructing the pipeline or temporarily shutting down and maintaining the system. S32750 Super Duplex Steel Blind Flanges are extensively used in a range of industries, including chemical processing, construction, water treatment, oil and gas production, shipbuilding, power generation, pharmaceuticals, and food manufacturing.
S32750 Super Duplex Steel has the following chemical composition:
- Carbon (C): maximum 0.030%
- Manganese (Mn): maximum 1.20%
- Silicon (Si): maximum 0.80%
- Phosphorus (P): maximum 0.035%
- Sulfur (S): maximum 0.020%
- Chromium (Cr): 24.00-26.00%
- Molybdenum (Mo): 3.00-5.00%
- Nickel (Ni): 6.00-8.00%
- Nitrogen (N): 0.24-0.32%
- Iron (Fe): minimum 58.095%
The S32750 Super Duplex Steel Blind Flanges have a wide range of applications due to their excellent overall performance. They are commonly used in basic projects such as chemical industry, construction, water supply, drainage, oil, light and heavy industry, refrigeration, health, plumbing, fire protection, electric power, aerospace, and shipbuilding.
The technical parameters for their application include nominal pressure of seal Pn, Mpa (bar), and the type of surface, which can be concave and convex surface (MFM), tenon and groove surface (TG), or full plane (FF). The applicable size ranges from DN300 to DN3000, depending on the type of surface.
