Introduction to Steel Pipe Flange
Steel pipe flanges are crucial components in piping systems. They are used to connect pipes, valves, pumps, and other equipment to form a complete pipeline system. Flanges provide easy access for cleaning, inspection, and modification of the pipeline. They are typically made of various materials such as carbon steel, stainless steel, alloy steel, and can be classified into different types including weld - neck flanges, slip - on flanges, blind flanges, socket - weld flanges, and lap - joint flanges according to their structures and applications. The quality of steel pipe flanges directly affects the safety and reliability of the entire piping system, so choosing a reliable manufacturer is of great importance.
