2009 flange defined
Also known as the flange or flange, a pipe.
Flange (plate) is part of the tube and the tube connected to each other. Connected to the pipe end, the general flange holes, you can
wear the bolt so that the two flange abuts. Between the flanges with gasket seal. Flange pipe fittings refers to with a flange (flange
or disk access) pipe. It can be molded (Figure N) constitute by threaded connection or welded. Flange connected by a pair of flanges, a
gasket and a number of bolts and nuts. On the two flange sealing surface between the gasket, and tighten the nut on the gasket surface
deformation than the pressure reaches a certain value, and fill the Office of the uneven surfaces of the sealing surface, so that the
connection not leak tight. The flange connection is a removable connection. Connected components can be divided into the container
flange and pipe flange. Sub-structure type, with integral flange, loose flanges and threaded flange. Common integral flange welded
flange and welded flange. Flat welding flange, less rigid, for
The pressure p ≤ 4MPa the occasion; welded flange, also known as high-neck flange, rigid, applicable to high temperature in the
pressure of the occasion. There are three type of flange sealing surface: planar sealing surface, suitable for high pressure, medium
nontoxic occasions; bump sealing surface, for slightly higher pressure situations; tongue and groove sealing face, applies to flammable
and explosive toxic medium and high pressure applications. The gasket is a plastic deformation, and has the ring of a certain strength
of materials. Most of the gasket is cut from the non-metallic plate down, or by a professional factory production of the required size,
the material is asbestos-rubber sheet, asbestos, polyethylene board of asbestos; also useful for sheet metal (white metal, stainless
steel) non-metallic materials wrapped made of metal-clad gasket; there is a band together around the system from the thin strip and
asbestos spiral wound gasket. Ordinary rubber gasket applies to a temperature below 120 ℃ occasions; asbestos rubber gasket for steam
temperature below 450 ℃, the oil temperature below 350 ° C, the pressure is lower than 5MPa occasions for general corrosive media, the
most commonly used acid asbestos board. In the high-pressure equipment and piping, copper, aluminum, metal gasket on the 10th of steel,
stainless steel, lens type, or other shapes. High-pressure gasket and sealing surface of the contact width is very narrow (line
contact), the sealing surface and the gasket processing finish higher.
Baidu Baike the definition of the flange: threaded connection (wire tapping) flange and welded flanges. Low pressure small diameter
wire, flange, high pressure and low-voltage large-diameter welded flange different pressure on the thickness of the flange and the
connecting bolt diameter and the number is different.
According to the different levels of pressure, flange pad of different materials, from the low-pressure asbestos pads, high pressure
asbestos pad to the metal pad has.
A material divided carbon steel, cast steel, alloy steel, stainless steel, copper, aluminum, plastic, argon Ge Lek, ppc, etc..
To the division of production methods can be divided into push the system, pressing, forging, casting and so on.
(3) can be divided into GB, standard electric, water standard, American standard, German standard, Japanese standard, the Russian
standard, such as the division of manufacturing standards.
