Q: Can different sizes of flanges have an interface that allows them to be joined together?: Variable diameter flange, also known as Reducing Flange, and its inner diameter and the standard flange diameter, there are some differences.In engineering, when the standard flange can not match the fittings and pipes, the reducing flange is used.China's national standards flange standard (GB) and chemical industry standard (HG) two categories, the new chemical industry standard HG/T20592 ~ 206352009 flange is used to the EN as the representative of the European standard pipe flanges (nominal pressure expressed by PN) and the United States as the representative of the American ASME system (nominal pipe flange the pressure expressed by Class), between them the nominal size of the feature size is different; moreover, our country pipeline diameter series is also divided and metric Inch series series, there are differences in the nominal size; in addition, when there are special requirements, such as flange instrument joints, when the glass lined the characteristics of some special requirements (give it a separate "glass lining of different diameter flange" HG/T2140-2009 standard). Therefore, the inevitable mixing in the project, the use of reducing the flange diameter of the method is the simplest and most effective solution, thus the emergence of non-standard variable flange.

Q: What's the size of the 1 inch flange? What's the thread of the hole on the flange?: 1 inch flange is 4 holes, the size of the hole to be, according to the pressure size minimum 11, maximum 18. Matching thread M10~M16.Flange:Flanges (Flange), also called 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. 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".Reducer flange for motor and reducer connection, as well as reducer and other equipment between the connection.

Q: What's the advantage of flange bolts?: The flange is the connecting device of two big diameter pipes, usually two flanges and some fastening bolts. Carbon steel flanges are flanges made of carbon steel. Low carbon steel, good plasticity, low strength, after adding a proper amount of carbon elements will become hard, plastic reduced, strength increased.Flanges may be subject to high tensile, compressive, torsional, and shear strength, and carbon steel flanges are preferable. Nominal pressure should be determined not only according to the maximum working pressure, but also according to the maximum operating temperature and material characteristics, not just the nominal pressure but the working pressure.

Q: What do you mean by flange 2''3'' 4''?: It should correspond to DN50, DN80, DN100 flanges

Q: What do butt welding flanges WN300-150, RF, Sch40s mean?: Butt welding flange WN300-150, RF, Sch40s mean:WN means neck welded flange;300 indicating nominal diameter of flange is 300mm,150 refers to the flange nominal pressure of 150LB (pounds), usually only the American system will use pounds to indicate nominal pressure;RF indicates that the sealing surface of the flange is in the form of a common face seal,SCH40 indicates the thickness of the steel pipe with neck. The neck flange and the welding ring and loose flange of the general neck should be filled in the specifications and the wall thickness of the pipe diameter should be filled out.

Q: CAXA2011 machine version, the big flange bolt hole evenly distributed, how to give the centerline?: 1) implementation of array command immediately pop-up menu, the menu and operation instructions immediately according to the current requirements, can make a circular array, the array array graphics results for the uniform distribution, a number of 4.2) pick up the elements with the mouse, pick the graphics into bright red display, pick up, with the right mouse button to confirm. As an operation prompt, the result of an array copy is displayed when the center point and the base point of the array pattern are picked up with the left mouse button. The meaning of [central] and [reference] points can be seen by tagging.3) the system automatically rotates the graph in the array according to [2: rotation] in the immediate menu.4) the system automatically calculates the positions of each insertion point according to the [3: evenly distributed] and [4] numbers in the immediate menu, and the angles between the points are equal. The array patterns are evenly arranged on the same circumference. The share value should include the entity picked by the user.5) with the mouse click on the immediate menu [3: evenly distributed], the immediate menu is converted to the content shown in figure 4-47.The meaning of the immediate menu is that a circular array is arranged in a given angle, the angle between the adjacent figures is 30 degrees, and the filling angle of the array is 360 degrees. The array filling angle meaning to the entity from the pickup location, around the center of the inverse angle clockwise turn, adjacent angle and filling angle can be determined by the array of keyboard input.

Q: What is lined with PTFE stainless steel flanges?: Since it is lining PTFE, corrosion resistance enough, carbon steel is not OK, but also made of stainless steel flange do? Outside air corrosion is considered cheaper than stainless steel.

Q: There are two flanges at each end of the pipe, one of which is marked as below. What is the standard flange?: This is an international standard flange. Nominal diameter DN100 of the back of the F is convex meaning

Q: In the pipe installation, the three way, the elbow, the big head and the flange do not need the quota?: Clamp, three links, four links, elbow, reducer can be directly fixed in the pipeline inside the material content. Three pass, four pass, elbow, big head need not coat quota. Above DN100 shall be also included in the wood, do not need another coat of quota. As a result of different standards throughout the country, the key is whether the set of fixed pipe installation includes pipe fittings, first look at the specifications, engineering calculation rules, and then set the quota, there will be no duplication of calculations and omissions.Method of setting quotas:1.. What project quantity sets what quota, find the amount of project quota that you need first.2. understand the base price. The price is fixed in artificial materials machinery (+ +, it is note that units) are now consumption quota, consumption is the loss of quota book has made it clear that each of the different material loss, this loss is fixed price price * material.3. price conversion. If the artificial, material, machinery in a price change will require a change to the original conversion price, the price deducted from the price, then the changes added to form a new price.

Q: The choice of flanges for the European system and the American system: Chemical flange specification must specify flange specification numberIn our country, the important use is chemical flange specification HG. As a result of the two set system, namely the European system and the American system. The flange specification number is different. As these two sets of system flange size is different, so the same as the chemical flange specifications HG, but it will not match, only to specify the chemical flange specifications, in order to ensure that each other correctly.The usability of flange under different pressure levels is discussedIf you use the different specifications of each country, you must also specify the flange specifications. In practice, through careful comparison, each standard system is different, such as chemical flange, European system, flange in DN less than 100, in the same DN, its flange diameter, screw number and size the same. Therefore, it can be used for automatic control specialty. If the project to PN=1.6Mpa, and the instrument marked is PN=2.0Mpa, if it is chemical flange HG20592-97 European system, only pressure grade allowed, it can match the whole.Chemical flanges specification American system CLASS 150 and CLASS 300 have no versatilityAfter careful comparison, the chemical flange specification American system 5.0Mpa (ie CLASS 150 and CLASS 300) below the pressure level is not universal, and this is different from the European system, use should pay attention to.
