A plate flange is a type of flat circular fitting that is used to connect pipes, valves, pumps, and other equipment to each other or to other components in a piping system. It is called a “plate” flange because it is essentially a flat piece of metal with bolt holes drilled around its circumference. The plate flange is typically bolted to another flange or component using bolts and nuts.
Plate flanges come in a variety of materials, such as stainless steel, carbon steel, and alloy steel, and can be designed to handle different pressures and temperatures depending on the specific application. They are often used in industrial settings where high pressure and temperature are present, such as in oil and gas processing, chemical plants, and power generation facilities. Plate flanges are also commonly used in plumbing and HVAC systems for residential and commercial buildings.
