Stainless Steel Flanges overview

Flanges are essential components used in numerous applications to connect piping systems. They provide a robust and secure way to connect pipes, valves, pumps and other components together. Depending on the material, stainless steel flanges are particularly resistant to corrosion and are ideal for use in demanding environments such as the chemical, petrochemical and food industries. Thanks to their versatility and high resilience, they are widely used in many industrial and commercial applications.

Product features

Flanges are available in different types and sizes to meet different needs. The most common types include:

  • Weld neck flanges: Ideal for high pressure requirements and a long-lasting connection.

  • Loose flanges: Flexible in use and easy to assemble, often used in conjunction with smooth collars.

  • Blind flanges: For sealing pipelines and performing pressure tests.

  • Threaded flanges: Easy to install, no welding required.

Specifications and dimensions

The specifications and dimensions of flanges vary depending on the application and requirement. Typical examples include:

  • Diameter: From 15mm to 600mm.

  • Nominal pressure: PN 6 to PN 40.

  • Materials: Stainless steel 1.4541 (321), stainless steel 1.4571 (316Ti)

These flanges meet European and national requirements Standards such as EN 1092-1 and DIN 2576, which enable the highest quality and safety standards.

Benefits and Applications
