Q:The difference between groove flange and high diameter flang: The difference between: 1, groove flanges are used in fire and water piping. High neck flanges are commonly used for high temperature, high pressure, inflammable and explosive, highly toxic, and the clean cleaning requirements in the pipeline.

Q:Different sizes of flange connections: The size of the diameter Flange and the diameter Flange is different from the standard Flange diameter. In engineering, use the variable diameter flange when the standard flange cannot match the pipe and pipe. Flange standard of our country has the national standard (GB) and chemical industry standard (HG) two categories, the latest chemical industry in the flange standard HG/T20592 ~ 20635-20635 and adopted by eu EN European tube flange standards (nominal pressure using PN) and the United States represented by the ASME American pipe flange system (nominal pressure using the Class), feature sizes between them in the same nominal size there is also a difference; Furthermore, the series of pipe diameters in China is also a series of metric series and English series, which are also different in the nominal size of the same class. In addition, when there is a special process requirements, such as instrument fittings, glass lining flange of its characteristics and some special requirements (give it another made the glass lining flange diameter "HG/T2140-2009 standard). Therefore, in the inevitable mixed appeared on the engineering situation, reduce the size of the flange diameter method is the simplest and the most effective solution, thus appeared the non-standard adapter flange.

Q:Why does the bolt hole of the flange be arranged across: Convenient installation; Uniform standards that facilitate design; According to the mechanics structure, the span is evenly distributed, and the service life is extended. The bolt hole is the hole of the bolt hole which is set up for the foundation of the equipment when the concrete is cast. Bolts: mechanical parts, cylinder threaded fasteners with nuts. By the head and the screw (with external thread of the cylinder) of two parts of fasteners, to cooperate with nut, used for fastening the two parts with hole. This form of connection is called a bolted connection. If you screw the nuts from the bolt, you can separate the two parts, so the bolted connection is a removable connection.

Q:Can you install the flange?: You can. Flange installation is to put the two pipes, fittings or equipment, fixed on a flange, a first between the two flanges, plus the flange gasket, bolt fastening together, complete the connection. Some pipes and equipment already have their own flanges, which also belong to flange connection. Flanged installation is an important connection of pipe construction. Flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flanges are widely used. In the home, the pipe is small in diameter and is low in low pressure, and no flange connection is visible. According to the installation type can be divided into: connection flange plate flat welding flange, with flat welding neck flange, butt welding neck flange, socket welding flange, threaded flange, flange cover, with neck butt welding ring flange, ring flat welding flange come loose, ring groove surface flange, flange cover, large diameter plate flange, large diameter high blind flange, butt welding neck flange, eight words ring flange, etc.

Q:What are the characteristics of welding and flanged connection: All steel pipes, aluminum pipes and copper pipes can be joined. Flange connection is the two pipes, fittings or equipment, fixed on a flange, a first then add flange gasket between the two flanges, the last two flange bolts will tighten the close combination of a detachable connection.

Q:The flange is round only? Well?: B: yes, it is. There are all kinds of flanges.Of course, there are too many varieties to see the installation need.

Q:What do PPR tube flanges do to relax: Adjust the injection molding process, increase the pressure or time of the pressure, or increase the cooling time. If you cannot adjust the process, you can increase the mold core

Q:What is the main difference between flanged and flanges and flanges and flanges?: Flange a, flange b, in the pipe fittings, only call different. Plastic flanges flange root, root for plastic pipes or composite pipe connection, a connection surrounding edge and connection in combination with surface, connection around the edge no connection bolt hole, its connection in combination with surface has a circular groove seal installation. The utility model by setting the circular groove equipped with sealing ring, make plastic flange sealing of root connection becomes easy, sealed performance is good, also need not too much for connecting flange of locking force, easy construction, protection of the flange, greatly extend the service life of the flange, alternative steel flange is used, the utility model is particularly suitable for the mine negative pressure suction gas pipe connection. 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. Flanged is a kind of PE pipe, flanged piece is called the steel flange, and the flange is called cast-iron pipe.

Q:What is a flanged water meter: The flanged water meter is the water meter of the flange connection. Flange connection is the two pipes, fittings or equipment, fixed on a flange, a first then add flange gasket between the two flanges, the last two flange bolts will tighten the close combination of a detachable connection.

Q:Which length is the nominal size of the flange? What is the nominal diameter of the pipe?: The nominal size of flanges does not represent any flanges and the size of the flanges is only specified by the flange standard! For example, DN100 doesn't mean that the diameter of the flange is 100 depending on the pressure of the flanges, the size of the standard.
