What are Stainless Steel Flanges?

SS flanges serve as integral components in piping systems, linking two segments securely. They facilitate a pressure-tight connection and allow convenient access for inspection, cleaning, or modifications. Typically crafted from stainless steel, these flanges exhibit robust corrosion resistance and strength, rendering them suitable for diverse applications. Their remarkable ductility ensures reliable sealing across varying temperatures, preventing leakage or deformation. Additionally, stainless steel flanges boast excellent fatigue strength and outstanding resistance to creep, making them well-suited for challenging conditions like high temperatures and corrosive environments.

What are the standards for stainless steel flanges?

An SS flange, or stainless steel flange supplier, is crafted from stainless steel materials. Commonly adhering to material standards such as ASTM A182 Grade F304/L and F316/L, these flanges come in various Grades and pressure ratings, ranging from Class 150, 300, 600, to 2500. They find extensive use across industries due to stainless steel’s superior resistance to corrosion, offering improved performance in challenging environments. Additionally, stainless steel flanges present an aesthetically pleasing appearance, distinguishing them from carbon steel alternatives.

Various standards outline the essential chemical composition, dimensions, pressure ratings, and other criteria for materials used in piping system flanges and fittings. Notable standards for stainless steel encompass:

  • AWWA C228 –  which establishes the minimum material requirements and dimensions for stainless steel flanges in stainless steel piping systems.
  • ASTM A182 – which covers forged or rolled components for piping systems designed for high-temperature service.
  • ASME B16.5 – a dimensional standard applicable to pipe flanges and flange fittings, including those made of stainless steel.
  • ASME B16.34 – a pressure/temperature rating applied to threaded and welded valves connecting flanges.
  • ASME B16.47-  specifically addressing large-diameter steel and stainless steel flanges.

Advantages of stainless steel flanges

Explore the  benefits of stainless steel flanges in industrial applications. With exceptional corrosion resistance from chromium, they ensure longevity in challenging environments. Their resistance to chemical corrosion and oxidation makes them versatile. The polished finish adds aesthetic appeal and minimizes corrosion risk. The strength and resilience of stainless steel surpass basic carbon steel and outperform alternatives like aluminum, making them reliable in various conditions. Whether handling stress, temperature fluctuations, or ensuring a secure seal, stainless steel flanges consistently deliver outstanding performance, making them essential in industrial systems.
