PN10 DN250 WeldNeck Flanges

Flange, in addition considered as flange or flange. It is the phase that connects pipes to pipes. Connected to tube end. There are holes on the flange, and bolts can be worn to make the two flanges tightly connected. The flanges are gasketed. Flanged pipe fittings are pipe fittings with flanges (flanges or joints). It can be cast, threaded or welded. flange joints (flange, joint) are normal of a pair of flanges, a gasket, and severa bolts and nuts. The gasket is located between the sealing floor of the two flanges. After tightening the nut, the unique stress on the ground of the gasket will be deformed after carrying out a superb value, and the uneven section of the sealing ground will be filled, so that the connection is tight and no longer leaking. Some pipe fittings and tools have their very personal flange, in addition belong to the flange connection. Flange connection is an vital connection mode in pipeline construction.
Flange connection is available to use and can face up to giant pressure. Flange connection is particularly used in industrial pipeline. In the home, the pipe diameter is small, and is low pressure, no longer seen flange connection. If you are in a boiler room or a manufacturing site, there are flanged pipes and tools everywhere.
The reason of the flange is to tightly closed and seal the joint of the pipe fitting. Flange is usually used to be a phase of tight pipes, pipe fittings, etc., and keep the sealing ordinary regular basic performance of pipe fittings; Flange detachable, reachable to disassemble take a exhibit up at pipe condition.
