Flanges are mainly used for connecting pipes to pipes, as well as pipes to equipment.

Flange connection is an important method for pipeline construction. It is convenient to use and can withstand relatively high pressure. In industrial pipelines, flange connection is widely applied. It is commonly used in industries such as chemical engineering, petroleum, natural gas, water conservancy construction, vessel manufacturing, and mechanical equipment manufacturing. In households, where pipe diameters are small and the pressure is low, flange connections are rarely seen. However, in a boiler room or a production site, pipelines and equipment connected by flanges can be found everywhere.
