seamless black steel pipe

Q:What does the 25*3 of flange material specification (angle steel) mean?: The model does not mean the size of the different edges and sizes of the same model. Therefore, the width, the edge and the thickness of the angle iron should be filled out in the contract and other documents, so as not to be indicated by the model alone. Standard Specification for hot-rolled equal angle iron is 2#-20#.Application: the angle iron can be made up of different force components according to the different structure.

Q:Oil seal flange: Flange (flange) high pressure flange (SAE flange JBZQ 4187-97), also known as flange or flange. A part that connects the pipe to the pipe and is connected to the end of the pipe. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Fittings pipe (flanged) means a pipe with flanges (flanges or plates). It can be formed by casting and (figure not available), may also be threaded or welded together. The flange joint (flange, joint) consists of a pair of flanges, a gasket, and a number of bolts and nuts. Gasket on the flange sealing surface between the two, tighten the nut, the gasket on the surface pressure reaches a certain value after the deformation, and fill uneven sealing surface, so that does not leak tight connection. A flange connection is a detachable connection. The connecting parts can be divided into vessel flange and pipe flange. According to the structural type, there are integral flanges, looper flanges and threaded flanges. There is a common integral flange flange and butt welding flange. Less rigid flange, suitable for pressure P is less than or equal to 4MPa occasion; also called high neck flange welding flange, large rigidity, suitable for high temperature pressure.

Q:60 seamless steel tubes with 50 flanges, right?: On the next floor, the DN50 seamless pipe has an outer diameter of 60.3 and a flange with DN50. Of course, corresponding to their thickness of SCH? The same thing.

Q:What's the flange? What's it for?: Flange (Flange), also called flange or flange plate. The flange is the part that connects the pipe to the pipe and is connected to the end of the pipe. It is also used for the flange on the inlet and outlet of the equipment. It is used for the connection between the two devices, such as the reducer flange. Flange connection or flange connection, is defined by the flange, gasket and bolt connection between the three sealing structure of the detachable connection as a combination of group pipe flange refers to the pipeline installation of piping flange, used in equipment refers to equipment import and export flange. The flange is lined with bolts to secure the two flanges. Gaskets for gaskets between flanges. Sub threaded flange connection (threaded connection) flange and welding flange and flange clamp.

Q:How many kinds of flanges are there?: 4. according to the material for making flangesAccording to the flange material can be divided into: cast iron flange, steel flange, plastic flange, copper flange and so on.At the same time, there are 4 standards for flanges in our country, namely, versatility and specificity. Each flange standard is not limited to the scope of this trade, but it is crossed and permeated. In order to gradually unify the flange standard, the National Machinery Committee has formulated a series of flange standard, where GB/T9112~9124 - 2000 "steel pipe flange" series standard is quite comprehensive, but this does not mean the national standard to replace the other flange standard. HG/T20592~20635 - 2009 "steel pipe flanges, gaskets and fasteners" is adjusted and revised based on the original HG/T20592~20635 - 1997, which is set by European and American system system respectively in the preparation of pipe flange standard system, clear and operational use.

Q:What's the flange? What is its structure and function?: Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.

Q:PROE flat sheet metal design whole wall and the flange wall what is the difference?: General flat wall more, but both are useful, if a sheet folded 8 bend, flange 8 bending murals in the shape of a stretched out, but with a flat wall is painted 8 times,

Q:RJ what flange is the sealing surface?: RJ is the flange ring connection surface.Flange sealing surface type:Full plane FFProjection RFConvex MConcave FTenon face TGroove surface GRing joint surface RJGeneral concave convex MFTongue and groove face TG

Q:How about copper tubes? TenCan plastic pipes be flanged? Can it bear the pressure of the bolt?: The steel pipe, the aluminum tube and the copper pipe can be flanged connected.Flange connection is the two pipes, fittings or equipment, each first fixed on a flange plate, and between the two flange with flange pad, finally by bolt two flange of a detachable joint tension so closely together.purposeThis connection is mainly used for cast iron pipe, lining hose, non ferrous metal pipe and flange valve, etc., the process equipment and flange connection is also using flange connection.The main feature of flange connection is convenient disassembly, high strength and good sealing performance. When installing flanges, the two flanges shall be kept parallel and the sealing surfaces of flanges shall not be damaged and shall be cleaned.

Q:What is the reverse flange?: Flanges are used in pairs. Low pressure pipes can be made of wire flanges and welded flanges with pressures of more than four kilograms. Add a gasket between the two flanges and secure with bolts. Different pressure flange thickness is different, they use the bolt is also different. Water pump and valve, and in the pipe connection, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts that are bolted and closed in the vicinity of the two planes are generally referred to as flanges, such as the connections of the ventilation ducts, which can be called flanges". However, this connection is only part of a device, such as flanges and pumps connected, it is not good to call the water pump flange parts". Relatively small, such as valves, can be called flanges".
