The welding technique of these is fillet weld, and thus these are not suitable for high pressure applications. Provided products are are resistant to corrosion. Proffered with a superior grain structure, these Stainless Steel Plate Flanges have extended service life.
Plate flange is a piece of steel in the form of a ring, which has holes for fastening the flange to the elements of the pipeline with bolts or studs. The steel flange is put on the pipe and welded to the joints with it, after which another flange is welded to the flange through a special gasket by means of fastening, welded to another pipe, pipeline element or instrument.
The ASME B16.5 Plate Flange also referred to as a plain flange is a flat circular disk which has an inner bore along with bolt holes on it. In addition to this, the Plate Flange is known as a flat flange.
Since the inner hole of the Flange Plate tends to be a little bigger in comparison to the outer diameter of a pipe, the steel plate flanges could be easily slipped over the pipe. These stainless steel grade ansi plate flanges can be secured to the pipe by using a fillet weld at the bottom as well as the top of flanges with the pipes.
As the welding method used on these flanges is a fillet weld one, therefore these ANSI B16.5 Plate Flanges are not well suited for those applications which involve high pressure. An advantage offered by Stainless Steel Plates Flange is that they are generally resistant to corrosion across several media. However, the grade of stainless steel used in the manufacture of the Backing Plate Flanges will vary, depending upon the requirement of the application.
