Some of pipe fittings and equipment have been built-flange, also falls within the flange connection.
Sub-threaded flange connection (wire tapping) flange and welding flange. Low-pressure small-diameter wire access flange, high pressure and low pressure are the use of large-diameter welded flange, different pressure, flange thickness and bolt diameter and the number of connections are different.
The different grades based on the pressure, flange pad also has a variety of materials, from the low-pressure asbestos pad, high-pressure pads to the metal pads are asbestos.
Flange easy to use, able to withstand greater pressure.
In the industrial pipeline, the use of a wide range of flange connection. Within the family, pipe diameter is small, but also ow-voltage, see flange connection. If a boiler room or a production site, full of flanged pipes and equipment. Flange connection is to two pipes, fittings or equipment before each fixed at a flange on the flange between the two, together with flange pad, fastened together with bolts to complete the connection. Some of pipe fittings and equipment have been built-flange, also falls within the flange connection.
Note that connection, especially when the bolt fastening the time to do the same as all the bolts tight.
