Q: The motor and the speed reducer can be flanged: You can use the flange or the coupling directly with the motors and the reducer

Q: The flange is round only? Well?: There are many shapes of flanges, the most common are round, and there are square, elliptical, diamond, triangle, and also commonly used in the eight word blind flange!

Q: What is the difference between the common flange and the traditional flange: Flange connection is easy to use and can withstand greater pressure. In industrial piping, flange connection is widely used, such as in indoor fire hydrant water supply system, butterfly valve, gate valve, check valve and other kinds of valve and pipeline connection.

Q: The average distribution diameter of the flange is 8. How is his position marked?: Find the diameter of the circle in the center of the hole, and then divide the circle into four equal points. Note it is best to 45 ° points.. Mark mark center when the diameter of the circle and 45 °.

Q: What does the flange do?: Flange connection is convenient to use, can withstand greater pressure. In industrial piping, flange connection is widely used. Within the family, pipe diameter is small, and it is low voltage, invisible flange connection. If in a boiler room or production site, the flange connection of pipes and equipment are everywhere. In general, the effect of a flannel is to keep the connection of the pipe in place and seal.

Q: What is the size of an inch flange? What is the thread of the hole in the flange: The flanges are used in pairs, and the low pressure pipe can be used with wire flanges, and the welding flange is used for more than four kilograms of pressure. Between two flanges, add a gasket and tighten the bolt. The flange thickness of different pressure is different, and the bolts they use are different. Water pumps and valves, when connected to pipes, are locally made of these devices, also known as flanges, also known as flanges. Where there are two surfaces around use bolt connection closed connection parts at the same time, generally referred to as the "flange", such as ventilation pipe connections, this kind of parts can be called "flange parts". But this connection is only a part of a device, such as a connection between a flange and a pump, and it is not good to call the pump "flanged parts". Smaller valves such as valves can be called "flanged parts".

Q: What is the waterline flange, and what is the difference between the common flange?: Outburst in order to increase the surface of the flange sealing surface and the contact friction between the pads and sealing, and sealing surface there are two interfaces for the concentric circles of the triangle groove (commonly known as water line), as shown in figure (a). Two waterline grooves were converted to the waterline, which improved the sealing of the flanged flanges, but the condition was that soft gaskets must be used. HG 20592-1997 only specifies the sealing surface of the flanged flanges, while HG 2052-2009 stipulates that all three of these flanges are covered in the waterline.

Q: Is the flange and the shaft the same thing?: Where there are two surfaces around use bolt connection closed connection parts at the same time, generally referred to as the "flange", such as ventilation pipe connections, this kind of parts can be called "flange parts". But this connection is only a part of a device, such as a connection between a flange and a pump, and it is not good to call the pump "flanged parts". Smaller valves such as valves can be called "flanged parts

Q: What is the technical requirement of the flange?: The flange connection should be kept in the same axis, the screw hole deviation is usually not more than 5% of the aperture, and the bolt is guaranteed to be free. The cover of the flange must be smooth, not in the direction of the radial groove and the sand eye. Flange gaskets should meet the standard and do not allow the use of slant gaskets or double-ply gaskets. When using the soft gasket, the peripheral should be neat and the gasket size should be in line with the cover of the flange. The inner diameter of the gasket should not be smaller than the diameter of the diameter of the diameter of the flange. When large diameter gaskets need to be spliced, they should be used in the form of oblique or maze, not to be flat. When installing, it can be coated with molybdenum grease, graphite oil or graphite powder according to the need, for the sealing of flange and the replacement of gasket.

Q: How do PPR and flange bond: The Flange is also called a Flange or Flange dish. The flange is the part of the pipe that connects the pipe to the pipe. Flange connection or flange connection, it is to point to by the flanges, gaskets and bolts are mutually connected as a set of sealing structure detachable connection, pipe flange refers to the plumbing for piping flange, used in equipment refers to the import and export of the flange of the equipment. There are holes in the flanges, and bolts make two flanges. The flange is sealed with gasket. Flange threaded connection (wire) flange and welding flange.
