Q:What is the center distance between flanges?
The flange of the center distance is from one end of the flange of the center section of the center of the reach, for example, a flange sealing surface from the center, and the connecting bolt hole center distance is from the middle of two holes corresponding to the middle, a hole, the most commonly used is the connecting bolt hole center distance the center of the flange, is we often say that the distance, I suggest you look at the hardware manual.
Q:What's the meaning of duct flange specification L20*4?
Angle steel classification and specifications: mainly divided into equilateral angle steel and unequal angle steel two categories, in which unequal angle steel can be divided into non equilateral, thick and unequal, unequal thickness of two kinds. The specification is expressed by length and angle of edge thickness size. At present, the domestic angle specifications for 2 - 20 cm, to length number number, the same horn steel often have 2 - 7 different edge thickness. Imported steel angles indicate the actual sizes and edges of both sides and indicate the relevant standards. Generally, the length of 12.5cm is larger than that of angle steel, and between 12.5cm and 5cm is medium angle steel. The angle of 5cm is smaller than that of angle steel. Inlet and outlet angle steel orders to use commonly required in the specification, the steel is carbon steel steel corresponding. That is, angles, apart from specification numbers, do not have specific components and performance sets. The delivery length of angle iron is divided into two kinds: the length and the ruler, and the length of the fixed angle of the made angle iron is four to 3, 9m, 4 - 12M, 4 - 19m and 6 - 19m. The length of Japanese steel angle is chosen from 6 to 15m.Wind pipe flange specification L20*4 is equal angle steel 20x20x4 flangeThe habit of writing equal angles is L*X*, L20*4 is 20x20x4 equal angles, and 4 is the thickness of the angle flanges,See the GB/T9787 angle standard
Q:Is the grooved pipe flange?
Grooved pipe fittings are a series of products. Flanges are only a kind of groove fittings.1, groove pipe fittings is a new type of steel pipe connecting pipe, also known as clamp connection, has many advantages.2, piping system shall be connected with groove type connection or flange connection, threaded pipe system; diameter equal to or greater than 100mm, should be used to segment the flange or groove type connector.3, groove fittings include two major categories of products:There are rigid joint, flexible joint, mechanical three way and groove type flange;The connecting pipe has the elbow, the three, the four, the reducer, the blind plate and so on.4 flanges are also called flanges, flanges, or flanges. A flange is a part that is connected between the pipe and the pipe and is 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.5, flange or flange joint, refers to the flange, gasket and bolt three mutual connection, as a group of composite sealing structure of removable connection. 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.6, in connection with the pipe, these equipment parts of the equipment also made corresponding flange shape, also known as flange connection. Any connecting parts which are bolted and closed in the vicinity of the two planes are generally called flanges, and this kind of parts can be called flanges.
Q:What does flange WN80 (B) -40M mean?
WN represents the flange type "neck flange"; 80 represents the nominal diameter is 80mm; (B) on behalf of the flange and pipe welding end diameter is B series (domestic use series, 89mm), representing 40 of the nominal pressure is 40bar; M represents the seal type is convex.
Q:What is the distance between bolts and holes for fire exhaust duct?
No specific requirements, it seems, preferably not more than 20
Q:Does anyone know whether oil, gas, metal pipe flanges need cross wiring? Function? On the basis of what?
4 and below flanges need to be bridged. In order to guide the static electricity.
Q:Servo reducer and servo motor connection, flange locking screw hole is M4.5, but servo motor installation hole is Phi 5.5, what will be the impact?
This depends on the mechanical swing, the big part, it is better to use 5.5 lock
Q:Who can provide plastic flange GB standards, it is best to give GB number?
The GB T9119-2000 plane, raised face plate welding steel pipe flangesGB/T 2506-2005 marine welding flanges
Q:What does "flange type" in electrical means mean?
The flange of many forms, function is connected and fixed with two parts, most people think about think of pipe flange (circular), in fact, it also has a square, trapezoidal, rhombic, according to the needs of processing, electrical construction generally used for explosion-proof pipeline and bridge, trough, to consolidate and seal the role of.
Q:Flange action
Flange action:A flange is a part that is connected between a pipe and a pipe and is used to connect the ends of the pipe;Also useful in the import and export of equipment flange, for the connection between the two devices, such as 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. 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".
