Stainless Steel 304 Flanges


Stainless Steel 304 Flanges
What is Stainless Steel 304 Flanges?

Stainless Steel 304 Flanges are an austenitic grade of components. These flanges have a chemical composition of 18% chromium and 8% nickel making them highly corrosion resistant in a range of environments. The flanges in the 304 range exhibit excellent forming properties and ensure a leak-proof sealing across the piping system. These flanges are designed to withstand high pressures and temperatures while managing to transport high volumes of fluids and gases.

Comparision A182 F304 SORF Flange and SS 304 WNRF Flange

The SORF and WNFR flanges are the two most popular flanges. These flanges have distinct characteristics, which differentiate them from each other.

  • SS 304 WNRF flanges are designed with a long protruding hub or head. SORF flanges are designed with a low-profile head.
  • A182 F304 SORF Flange is utilized for low pressure and temperature systems. The SS304 WNRF flange is a flange of choice in high pressure and temperature systems.
  • WNFR flanges are directly butt welded on the piping component. The SORF flange is slid on the component and welded using one or two filler welds.
  • SORF flanges are comparatively cheaper compared to standard WNFR flanges.
SS 304 Flanges Oil and Gas Application

Oil and gas systems emit corrosive by-products during their processing and refining. The SS 304 flanges are designed with a superior chemical composition of chromium and nickel. The composition creates a barrier and protects the flange against corrosion and oxidation. These flanges are very reliable and can transport oil and gas at high temperatures and pressures. The flanges within this grade ensure a smooth seal on these components thereby, preventing any leakage or spills.

DIN 1.4301 Blind Flange vs UNS S30400 Plate Flanges
  • DIN 1.4301 Blind Flange are special components, which don’t have a boring center or a hub. These flanges are designed to seal piping ends or act as blockages. They are generally bolted and allow the user to perform inspections or checks. Blind flanges resist high pressures and temperatures and securely seal the system.
  • UNS S30400 Plate Flange is a circular disc that is welded directly to a pipe bent allowing it to be bolted to another pipe. These plates are not suitable for high-pressure systems.
304 stainless steel Threaded Pipe Flange Features

The threaded pipe flanges are one of the versatile flanges in the 304 grade. Some of its features include

  • Threaded interior allowing it to correspond to different piping components.
  • Excellent corrosion resistance
  • Strong and secure seal
  • No requirement of welding
  • Provided with flat or raised face
  • Good choice for small size pipes
  • Useful in applications where post-weld treatment is not possible
  • Economical and time-saving
  • A flange of choice in explosive applications.
