PN6 Flanges GOST 12820-80

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 regular of a pair of flanges, a gasket, and severa bolts and nuts. The gasket is positioned 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 tremendous 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 equipment have their very non-public flange, in addition belong to the flange connection. Flange connection is an necessary connection mode in pipeline construction.
Flange connection is handy to use and can face up to giant pressure. Flange connection is especially 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 equipment everywhere.
The purpose of the flange is to tightly closed and seal the joint of the pipe fitting. Flange is typically used to be a phase of tight pipes, pipe fittings, etc., and keep the sealing usual normal overall performance of pipe fittings; Flange detachable, reachable to disassemble take a show up at pipe condition. Reducing flange corrosion resistance, acid and alkali resistance, can be used in water conservancy, electric powered powered powered power, strength station, pipeline fittings, industry, stress vessels and awesome aspects.
Stainless steel flange can be used for boiler stress vessels, petroleum, chemical, shipbuilding, pharmaceutical, metallurgy, machinery, elements and incredible industries, it is available to choice a area of pipeline.convenient to disassemble take a appear at pipe condition. Reducing flange corrosion resistance, acid and alkali resistance, can be used in water conservancy, electric powered powered power, power station, pipeline fittings, industry, pressure vessels and specific aspects.
