These industries prefer using Carbon Steel Flanges is because they are the least expensive amongst several alloy steel and stainless steel alloys. Although they are not particularly resistant to corrosion, their superior toughness, hardness and mechanical strength make up for its lack of corrosion resistance. However, this being said, in any case, if a buyer were to require some corrosion resistance properties at some level, low Temperature Carbon Steel Pipe Flanges could be surface treated by either undergoing galvanization or by electroplating. While both these processes coat the surface of flanges, making use of hot dip galvanization improves the corrosion resistance properties of Class 150 Carbon Steel Threaded Flange to a greater extent in comparison to electroplating.
Carbon Steel Flanges
ASME B16.5 CS Flanges
Carbon Steel Pipe Flanges
Carbon Steel Flanges is one of the most commonly used alloy grades across industries like petroleum, oil and gas.
In the oil and gas industry, using a High Yield Carbon Steel Plate Flanges proves to be an ideal choice since High yield carbon steels have the ability to withstand high pressure applications. Transporting and distribution of oil and gas across piping systems are often regarded as high stress causing application. The ASME B16.5 Standard is limited to 4 inch Carbon Steel Slip On Flanges and flanged fittings produced from cast or forged materials. The standard used to make ASME B16.5 CS Flanges need to follow the recommendations in terms of dimensions, tolerances, marking, pressure-temperature ratings, materials, testing, and methods of designating openings.
