Product name: What is a flange?
Description:
Fittings are widely used equipment for piping in various industries. Flange is one of the most widely used and important connections, especially in the oil, gas and petrochemical industries. Although the application of flange connections is not limited to these industries and has a wider range. In the continuation of this article, we will introduce the types of flanges, specifications, applications, standards and other related matters.
What is a flange?
A flange is a disc-shaped connection with holes around it at equal intervals. These parts are used to connect all types of pipes to valves, compressors, pumps and pressure vessels. In flange connections, first the flange disk is welded to the pipe and the desired part. Then the two discs are placed in front of each other and connected using bolts and nuts. The number of bolts and nuts required is also determined by the number of holes on the flange. In order for the flanged connection to be properly sealed, a gasket is used between the two discs.
Flange technical specifications
Most of the flanges used in the industry are produced from cast steel and cast iron or forging steel. Steel flange connections are more suitable for high pressure and high temperature conditions. Meanwhile, the cast iron flange connections, in the face of some stresses, separate or crack.
Flange features
To choose the right flange for connections, it is important to pay attention to some of its features. Some of these features include:
Size
Inner diameter, outer diameter, number and diameter of holes and suitable screw diameter are among the factors that are important in flange measurement. The size of this connection is selected based on the existing standards and other things such as the amount of pressure that is supposed to be applied to it.
thickness
Thickness is an important factor in choosing the type of flange. The amount of pressure that a flange connection can withstand depends on its thickness. The thickness of this connection should be such that the pipe used does not undergo deformation when bearing pressure.
material
Since the connections must be able to withstand pressure, humidity, temperature and different conditions, choosing the right flange material for each project is of particular importance. As mentioned before, the types of flanges are different. They can be produced from steel, cast iron, aluminum, brass, bronze and polyethylene.
In the following, we will examine the advantages and disadvantages of flanged connections.
Advantages of flanged joints
There are two methods for connecting pipes to each other or other equipment. One of the methods is to weld two pieces together and another method is to use flange connections. Although using a flange is a more expensive method, its advantages make it a better alternative to the welding method. These benefits include the following:
The assembly of this type of connection is simpler than the connection by welding. This is a huge advantage, especially in tight spaces.
