The flange is not familiar with it, it is actually a device that connects two kinds of mechanical equipment, a kind of disk part that is common in pipeline jobs. Due to its excellent connection performance, it has been rapidly promoted and it will be used in many places. But a lot of people still have a lot of questions about it? I'm going to answer for you today.
What kind of connection is flange?
Flange connection is an important connection method for pipeline construction. A flange connection is a connection between two pipes, pipes, or equipment, each fixed on a flange, between two flange discs, plus a flange pad, bolted together to complete the connection. Some pipes and equipment have already brought their own flange, which is also a flange connection.
Flange threaded joint(wire joint) flange and welded flange. The low pressure small diameter has a wire connecting flange, the high pressure and the low pressure large diameter are all welded flange, the thickness of the flange plate with different pressures and the diameter and number of connection bolts are different. According to the different levels of pressure, Falandian also has different materials, from low-pressure asbestos mats, high-pressure asbestos mats to metal mats. Flange connection is easy to use and can withstand greater pressure.
In industrial pipelines, flange connections are widely used. In the home, the pipe diameter is small, and it is low pressure, and the flange connection can not be seen. If you are in a boiler room or production site, there are flange connected pipes and equipment everywhere. A flange connection is a connection between two pipes, pipes, or equipment, each fixed on a flange, between two flange discs, plus a flange pad, bolted together to complete the connection. Some pipes and equipment have already brought their own flange, which is also a flange connection. Pay attention to making all bolts tight when connecting, especially when fastening.
What is the use of Frank?
Flange is used to locate. For example, an oil cylinder has a method of installation called flange installation. For example, a rectangular body is surrounded by four symmetrical holes, and a large hole in the middle is the same as the outer diameter of the cylinder. This rectangular body is placed on the cylinder. They can be welded together in other ways. The cylinder is connected to other things by four holes around this cuboid, which can be called Zuofalan.
What is the difference between Kongbanfalan's connection and ordinary flange?
That is, two pipes, pipes, or equipment are first fixed to one flange, two flange discs, plus flange pads, bolted together to complete the connection.
Kongbanfalan is the orifice flowmeter connecting the orifice plate(the measurement part of the orifice flowmeter) to the pipe. The two flanges fix the orifice plate in the middle and lead it to the differential pressure transmitter through the pressure point on the flange. To measure the flow.
4, to ensure that the installed flange does not leak oil, which issues to the installation attention?
The flange shall be of sufficient strength not to be deformed when tightened. Flange cover should be level clean, installation to carefully clean up oil and rust spots.
The sealing pad should have good oil resistance and anti-aging properties, as well as better elasticity and mechanical strength. Installation should be based on the shape of the connection to select different sections and dimensions of the sealing pad, and properly placed.
The strength of the flange should be uniform and consistent, and the compression of the pad should be controlled at about 1/3.
What are the main principles of flange selection?
For pipelines with a design temperature of 300 °C and below and a nominal pressure of less than or equal to 2 or 5 MPa, flat welding flange should be used: For pipelines with a design temperature greater than 300 °C or a nominal pressure greater than or equal to 4 or 0 MPa, Hanfalan should be selected.
