Intro: 

Plate Flanges
Plate Flanges, which are of wide variety, are manufactured mainly from plates. They are conforming to national & international standards and they are hubless. Plate flanges are produced from quality mill plates. Before cutting pieces out of plates, each plate is checked for serious laminations. They should be virtually free of voids, non-metallic inclusions and other defects. Another important property of plate is its weldability & hardenability. For more critical application of flanges, the hardness, strength and impact properties are also important factors. These properties vary through, along and across the section of the product as a result of temperature and microstructural variations during hot rolling, cold rolling or quenching and cooling.

In addition to our stock of standard flanges, we also offer specialty plate flange products which include machining details such as gasket surfaces, non-standard drilling, facing details, bevel and radius edges, o-ring grooves and raised or recessed faces. Some typical examples are shown below.

Plate Flanges
We offer a range of steel plate flanges such as steel slip-on flanges, blinds flanges, raised face flanges and back-ups flanges, in international standards like AWWA, DIN, BS, JIS, Czech, and Australian. Plate Flanges are available in sizes from 1/2" to 60" in Carbon Steel & Stainless Steel. Carbon Steel Plate Flanges are supplied with Anti-Rust coating of Oil, Clear Lacquer, and Black Japan. Carbon Steel Plate Flanges can also be supplied in Hot Dip Galvanized form.

Our Plate Flanges are developed from quality carbon & stainless steel and are available in distinct sizes ranging from 1/2" to 60".

Standard plate flanges can be customized to suit your application with a variety of machining details. The a-a section drawings below show some of the possibilities.
