What are the characteristics of welding and flanged connection
Use this kind of connection is mainly used for cast iron pipe, plastic lining, nonferrous metal and valve flange connection, flange connection of process equipment and use flange connection. The main feature of flange connection is disassembly convenient, high strength and excellent sealing. When installing flanges, the two flanges should be kept in parallel, the cover of the flange should not be touched, and should be cleaned. The gasket of flange is chosen according to the design regulation. Connection mode flange threaded connection (wire) flange and welding flange.
Low pressure small diameter wire connect flange, high pressure and low pressure of large diameter used welding flange, the thickness of the flange and the connection of different pressure bolt diameter and the number is different. Depending on the level of pressure, the flange pads also have different materials, from low pressure asbestos pads, high pressure asbestos pads, and teflon pads to metal pads. Flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flanges are widely used. In the home, the pipe is small in diameter and is low in low pressure, and no flange connection is visible. If you are in a boiler room or a production site, there is a lot of flanged piping and equipment
All steel pipes, aluminum pipes and copper pipes can be joined. Flange connection is the two pipes, fittings or equipment, fixed on a flange, a first then add flange gasket between the two flanges, the last two flange bolts will tighten the close combination of a detachable connection.
