AS2129 TABLE D FLANGE manufacturers tell you that flange connections are easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small, and it is low pressure, and the flange connection is not visible. If you are in a boiler room or production site, there are flanged pipes and equipment everywhere.

AS2129 TABLE D FLANGE manufacturers tell you that flange connection is to fix two pipes, pipe fittings or equipment on a flange plate, add flange pads between the two flange plates, and fasten them with bolts. Together, the connection is completed. Some pipe fittings and equipment already have their own flanges, which are also flanged connections. Make sure that all bolts are the same when connecting, especially when tightening the bolts.
What is the purpose of the flange? AS2129 TABLE D FLANGE manufacturers tell you that flanges are used for positioning. For example, there is an installation method for the oil cylinder, which is called flange installation. For example, four symmetrical holes are punched around a cuboid, and there is a large hole in the middle that is the same as the outer diameter of the oil cylinder. Putting this cuboid on the oil cylinder can be welded between them. The way is fixed together, the connection between the oil cylinder and other things is through the four holes around the cuboid, and the cuboid can be called a flange.
The above information is the AS2129 TABLE D FLANGE manufacturer's introduction and analysis of the use and purpose of flange, hope it helps you.
