The tapered hub helps to distribute stress more evenly along the flange and the pipe, making it suitable for high - pressure and high - temperature environments. Wn Flanges are widely used in industries such as oil and gas, chemical, power generation, and shipbuilding. They are available in different sizes, materials (such as carbon steel, stainless steel, alloy steel), and pressure ratings to meet the diverse needs of different projects.
