A Threaded Flange (Screwed Flange) is a type of pipe flange with internal threads, allowing pipes to be connected without welding. These flanges are ideal for low-pressure and non-critical applications where welding is impractical or not allowed.
Made from high-quality stainless steel such as SS 304, SS 316, SS 321, SS 347, SS 310, and SS 904L, threaded flanges provide excellent corrosion resistance, durability, and leak-proof connections.
