Stainless Steel 304 Flanges are some of the most commonly used grades of flange. These are used to connect two or more pipes or other piping components together. The ASTM A182 F304 Pipe Flanges are made up of the 304 austenitic stainless steel which is a chromium nickel alloy. The material is stronger and has some extent of corrosion resistance in general purpose applications.
Stainless Steel 304 Flanges
The tensile and yield strengths of the material makes it applicable for commercial, industrial and domestic applications. There are different types such as the A182 Gr F304 Slip on Flanges which are used to connect two pipes together by allowing the pipes to slip onto the flange. The ASME SA182 F304 Blind Flanges are used to seal the end of a pipe unlike the other flanges. The caps are important in piping to make sure a line is closed without leakages when necessary.
The flange sometimes need to be welded with an extra security. The UNS S30400 Weld Neck Flanges are made with a welded neck to them so that the joining and welding of the flange to the pies becomes easier and secure. The SS 304 RTJ Flange use rings that are attached to both sides of the connection so that the connection could be made stronger with bolting or welding.

A182 Gr F304 Slip on Flanges Build and Purpose
This is slipped over the pipe and then fillet welded which is produce from bar or plates and basically for corrosion resistance purpose. Easy to use in fabricated applications.
