Alloy Steel Flanges Manufacturer in India

Alloy Steel Flanges

We are leading Supplier and Stockist of Low AS Pipe/ Plate Flange

A flange is a lip or protruded hub that allows it to connect to different pipes, pumps, valves, and other equipment. The Alloy Steel Flanges are alloyed with different elements like molybdenum, nickel, manganese, chromium, and so on. The amount of alloying elements gives them good strength and resistance. The content of alloys makes them either high or low alloy steels. Low Alloy Steel Flanges have excellent ductility and showcase excellent creep strength. These flanges may have slightly lower strength but can be easily welded or fabricated in place. The Chrome Moly Flanges have exceptional resistance to corrosive media. These flanges have enhanced tolerance to pitting and work well across higher pressure and temperature setups. Alloy Steel Forged Flanges are produced after processing at higher temperatures. These flanges have a finer grain structure and a lower surface porosity. The ASTM A182 Flanges are a standard type of flanges that provide easy room for access, cleaning, inspection, and modification. These flanges can be both welded or screwed.

The Alloy Steel Slip On Flange is a hubbed flange that is slid on the pipe and welded using two filled welds. These flanges are available at reasonable prices but are primarily preferred in low pressure applications. Alloy Steel Weld Neck Flange can be recognized by the long tapered hub that is fitted gradually over the wall thickness of a pipe. These flanges can easily handle higher pressure and temperature conditions in different environments. The Alloy Steel Blind Flange is designed without a bore and is generally used to blank the ends of piping equipment to terminate the flow of media in the system. Our company is an Alloy Steel Flanges manufacturer in India who make use of the best raw materials and latest technology to produce quality-assured flanges in the industry.

How To identify Alloy Steel Flanges?

The various properties of alloy steel are determined by the composition and ratio of alloying elements. High-alloy steels contain more alloying elements than low-alloy steels, which only contain up to 8% of the total alloying elements.
