Stainless Steel 304 Flanges

SS 304 Forged Flange and ASTM A182 F304 Flanges suppliers in UAE

What are Stainless Steel 304 Flanges?

Flanges made of 304 grade austenitic stainless steel has 18% chromium and 8% nickel in its chemical composition. This is what makes the Stainless Steel 304 Flanges strong and resistant to general corrosive services. The ASTM A182 Grade F304 flanges are available in different sizes and surface finishes, which can be customised according to the client’s requirements.
There are different types of ASTM A182 F304 Flanges and they have different usages:

• The SS 304 Blind Flange helps to block off the end of a pipeline.
• The A182 Gr F304 Lap Joint Flange is used in a piping system that requires frequent dismantling for inspection and maintenance. The SA 182 304 Lapped joint Flange is also used in the erection of hard-to-adjust and large diameter configurations.
• The SA182 F304 Socket Weld Flange is found in small sized pipes with high pressure.
• The SA 182 Gr F304 Reducing Flange helps to connect two pipes of different sizes.
• The A182 F304 Slip On Flange is used low pressure applications that have a very little risk of leakage.
• The SA 182 F304 Weld Neck Flange can be used in severe and critical applications.
• The SS 304 Flanges are used as a fitting, which helps in forming a piping network with valves, pumps, and various other piping equipment.
• The ASTM A182 304 Plate Flange is mainly used in fuel and water pipelines.
• The 304 SS WNRF Flange is preferred for high stress applications.
• The DIN 1.4301 RTJ Flange is used in high temperature and high pressure piping applications. The Inox 304 Ring Type Joint Flange is found in oilfield assembly, high integrity pressure vessel joints, etc.
• The AISI 304 Screwed Flange comes with a screw thread which helps to connect the flange to the piping system.
• The SUS 304 Spectacle Blind Flange is installed to ensure uninterrupted flow inside the pipeline.
• The UNS S30400 SORF Flange can be used in both medium and low pressure pipelines.

Forging process of SS 304 Flanges

The F304 stainless steel Forged Flange is manufactured by heating the steel billet and then compressing the material with a steel hammer to give the flange the desired shape from its solid state.

What is difference between 304 Threaded Flange annealing and normalizing?

Annealing allows the 304 Threaded Flange material to cool down at a controlled rate inside a furnace. Whereas, normalizing allows the material to cool down at the room temperature.
