Flange connections

Flange connection is to two pipes or pipe pieces of equipment, each first end fixed to the top flange, the flange gasket between the two flanges together, bolted together, fixed. Some pipes or fittings equipment, already comes with flange, it also belongs to the flange connection.

 This connection is mainly used for non-ferrous metal pipes and flanges valves, cast iron pipes, rubber lined pipe connections, process equipment and flange connections also flange connection, the main advantage is the easy removal of the flange connection, high strength, density good, but must pay attention to the mounting flange must take to maintain a balance on both sides of the flange, flange sealing surface can not have a bump, where the manufacturer must also be noted that during transport flange sealing surface can not have a bump, and When you install must be clean, flange gaskets used to design requirements and more choice, can not be used indiscriminately.

Flanged connections are important to the main pipe fittings equipment construction time.

 Flange connection flange with threaded connection (including threaded flange, which is connected to the flange wire), as well as welding flanges. High pressure and large diameter flange welded flange connection mode, low pressure small diameter flange threaded flange connection mode, flange different caliber, different pressures flange, flange thickness and bolt diameter and the number of connections is different. Depending on the pressure flange, flange gasket there are different materials, there is a low pressure asbestos pads, high pressure asbestos pads, as well as metal asbestos mats, in accordance with the flange pressure rating procurement asbestos pad.

Flanged pipe fittings in construction and easy to use when disassembling, able to withstand greater pressure in the industrial pipe fittings equipment installation, flange connection is very common, is widely used in the family may not see the flange connection, if a boiler room or production site, everywhere flanged pipe and equipment connections.

Flange connections can now be said to be very common, as long as the construction site, there flange connection, flange connection is very easy to install, simple to operate, but also easy to disassemble.
