The difference between flange and flange B
1, the difference is that the pressure range, temperature range, medium toxicity range, optional gaskets are also different;2, welded flange, welded flange flange ring only, usually made of steel, forging and rolling can be used when necessary. In connection, it is directly welded with the cylinder or head. The whole flange ring and the cylinder head or connection, small stiffness and joint strength of welded flange, it applies only to a relatively low temperature and pressure. In the current industry, welded flange has 4 pressure levels (PN0.25, 0.6, 1, 1.6MPa), the scope of the nominal diameter is smaller (DN3002000mm), the working temperature range of 300 from-20 DEG C.Hepatitis B: the difference between flange flange to flange welded flange is the main ring with a short. Flange rings are usually made of steel plates or made of forgings. In connection with the short tube or head butt welding, the flange type B good integrity, its strength and stiffness than the welded flange. In the current industry, the pressure range of B flange is large, there are a total of 6 pressure levels (PN0.25, 0.6, 1, 1.6, 2.5, 4.0MPa). The nominal diameter scope is: DN3003000mm, suitable temperature: from-20 DEG C - 350.
Steel pressure vessel welded flange suitable for nominal pressure 0.25-1.6Mpa, operating temperature is higher than -20-300 DEG C.Steel pressure vessel flange type applies to nominal pressure 0.25-4.0Mpa, operating temperature is higher than -20-350 degrees.The fillet welds of type B and type A are different in size and different in size
What is the difference between a flange and B flange?:1, a V type groove, B U groove, so B easier penetration, so its strength and stiffness is higher; B flange with a short barrel, therefore is a rigid flange, can be used for high pressure, large diameter.2, welded flange and direct vessel welding, the weld size is smaller or the solution without groove welding, can not guarantee the flange and the container also force strength calculation reference looper flange. Welded flange should not use strict occasions in the inflammable and explosive and extremely harmful medium height, etc., can not be used in severe cyclic condition; B flange generally accompanied by a thick short barrel, short cylinder flange and welding quality, and also can ensure the flange container stress intensity the calculation can be considered as an integral flange. B flange is widely used in medium and low pressure vessels and piping connections.3 steel pressure container, a flange for nominal pressure 0.25-1.6Mpa, operating temperature is higher than -20-300 DEG C; steel pressure vessel flange type applies to nominal pressure 0.25-4.0Mpa, operating temperature is higher than -20-350 DEG C.Flanges, flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe, used for the connection between the ends of the pipe. It is also used for the flange on the entrance and exit of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange joint means that the flange, the shim and the bolt are mutually connected as a group of three detachable sealing structures. Pipe flanges are flanges used for piping in pipe installations. They are used on equipment and refer to the entrance and exit flanges of the equipment. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection), flange welding flange and flange clamp.
