Alloy Steel Flanges Manufacturer, Supplier In Mumbai India

Alpha Overseas is well known in the industry for its production and distribution of Alloy Steel Flanges. The grades and dimensions of low alloy steel flanges vary. We manufacture a variety of alloy steel flanges, some of the highest quality available. These flanges come in a variety of pressure capacities and classifications. For pressure piping, the specification is frequently ASTM A182, and their nominal diameter ranges from 12 inches to 48 inches. The Alloy Steel Flanges manufacturers are also employed in pipe systems to provide certain mechanical advantages. Pressure numbers from PN6 to PN64 and pressure classes from 150 to 2500 are available.

There are many types, uses, shapes, and faces for alloy steel flanges. There are various face types, including ring-type joint flanges, raised face types, and flat face types. The alloy steel lap joint flange is a unique form of a flange with a lap on it. The flanges are utilized to keep the pipes together in various industrial applications. Several manufacturing processes include threaded, welded, screwed, and alloy steel forged flanges. The raw material used to create the forged flanges is just one piece.

Alloy Steel Flanges, Chromium Molybdenum ASTM A182 Flange, Cr-Mo Material Weld Neck Flange, Chrome Moly Flanges, Alloy Steel Pipe Flanges, Alloy Steel Flanges Suppliers, Alloy Steel Slip On Flange, Alloy Steel Flanges Manufacturers in India.

Where rust indicates corrosive activity, these alloy steel slip-on flanges can be machined, shot-peened, and polished in as-built or stress-relieved states if necessary. Our alloy steel threaded flanges do not require solution annealing because they exhibit the desired mechanical characteristics in their as-built form.

These Alloy Steel Weld Neck Flanges are an exception since they have about 24 percent chromium and can be used to prevent scaling at temperatures as high as 1100 degrees Celsius. Our Alloy Steel Blind Flanges are contributed by environmental elements, including wind exposure, industrial pollution, and high temperatures. They are closer to the sea, a significant cause of salt water pollution. The high chromium content in these alloy steel weld flanges, which is advantageous to their resistance to wet corrosion, is also very beneficial to their high-temperature strength and resistance to scaling at elevated temperatures.
