Steel Pipe Flange

A steel flange is a mechanical device used in pipelines to connect pipes and provide support to valves, pumps, and other equipment. The steel flange consists of a flat surface with bolt holes, which are welded or screwed onto the end of the pipe. It provides a tight seal and prevents leakage by creating a continuous and permanent connection between the pipes. Steel flanges can be used in a range of industries, including oil and gas, chemical, petrochemical, and many others. They come in various sizes and types to suit different pipe sizes, temperatures, and pressure ratings. Steel flanges are manufactured using high-quality materials such as carbon steel, stainless steel, and alloy steel, making them durable and reliable for different applications.
