Flanges used to connect pipes in a particular piping system are easily available in the market. Alloy Steel Flanges Manufacturer In India produces these flanges as per international and in different grades to suit the needs of the application. Low Alloy Steel Slip On Flanges are available in the size range of ½ inch to 48 inches. Chrome Moly Flanges manufacturer In India recommends these flanges as they have a high content of chromium and molybdenum that helps in improving resistance to corrosion and hardenability. Alloy Steel Blind Flanges are used to terminate the pipe temporarily or permanently.
Alloy Steel Weld Neck Flanges are widely used in aerospace and automobile bodies, along with being used in offshore oil drill and onshore engineering. These flanges are also available with threads. Alloy Steel Lap Joint Flange that is threaded or screwed inside the flange bore fit onto the pipe with matching male thread. They have a pressure rating from class 150 to class 2500. These flanges also offer resistance to pitting and crevice corrosion along with offering good durability. AISI 4130 Flange offers properties that a regular carbon flange may fail to provide.
Alloy Steel Forged Flanges are used in water lines, chemical plants, food production systems, processing plants, and the oil and gas industry. Applications that demand the need of high pressure and high temperature AS Ring Type Joint Flanges are the most suitable option. We can even customize these flanges as per the needs of the customer. We pass these through various tests to ensure that they meet the required standard. ASTM A182 Alloy Steel Reducing Flanges manufactured by us are supplied to various customers across the globe at a comparatively cheaper price without compromising on quality.
