What are mannesmann fittings?
What are mannesmann fittings and what are their types?
In the piping system, the pipes must be connected to each other, and the type of connection must be appropriate to the type of pipe being worked; Therefore, when you use Mannheim pipes, you must use Mannheim fittings to connect the pipes. In the following, you will get to know more about Mannesmann's connections.
Features of Mannesmann fittings
So far we have said that we must use Mannesmann pipes for Mannesmann connections. Mannesmann pipe is a type of seamless pipe that, due to the lack of welding, is widely used in parts of the industry where the seamed pipe cannot have the necessary resistance. These pipes are produced in different types and sizes, of course, the main reason for the difference in the price of Mannesmann pipes (قیمت لوله مانیسمان) is the same difference in their thickness and size.
The most important feature of Mannesmann joints is their seamlessness. Because they have no welds or seams in their bodies, they have high quality and resistance and are used in sensitive piping systems such as gas and oil. It should be mentioned that Mannesmann connectors are manufactured and supplied in different categories, the 80 and 40 categories being the most popular among them.
What is the difference between Mannesmann fittings and seamed fittings?
Mannesmann connections are also known as seamless connections. The first difference between this type of connection and seamed connections is in the way they are made; In this way, welding seams are not used in the construction of Mannesmann joints in the body, but seamed joints are made using welding. Economically, the price of Mannesmann fittings (قیمت اتصالات مانیسمان بنکن ) is higher than that of jointed fittings; For this reason, this type of connection is used in sensitive and risky situations and is used for industrial piping systems such as oil and gas transmission.
How should we distinguish Mannesmann pipe from seamed pipes?
To distinguish Mannesmann joints from seamed joints only by appearance, it is enough to compare them visually. If you see or touch the inside of the welded joints, you will notice the protrusions that are the same as the welds. While you will not see this bump by touching or observing the Mannesmann joints. Of course, this is not the only way, and in some cases there is a hidden seam that you should be careful to buy from a reliable place so that they don't sell you seamed pipes instead of Mannesmann pipes.
Mannesmann fittings category
One of the most important features of Mannesmann fittings is that they are produced in different thicknesses and grades. These connections are usually produced with thicknesses of 40, 80, 160, SGP, and STD, which is very important to consider when connecting to pipes in the piping system. If we want to name the most common Mannesmann connectors, we should mention Mannesmann category 40 and Mannesmann category 80 connectors. You can click to know the price of Mannesmann 80 grade pipe (قیمت لوله مانیسمان رده 80). This size of pipes is used for branching and changing the path of the piping system. Note that each class of fittings is used to connect pipes of the same size.
All kinds of Mannesmann fittings
Mannesmann's connections have different types, each of which has its own characteristics and is used in certain situations:
One of the most widely used Mannesmann fittings are tee fittings, which are of 2 different types. One of them is for connecting pipes with the same diameter and the other is for dissimilar connections, by which one pipe is connected to 3 pipes with different diameters.
Gap Mannesmann fittings
To block the ends of the pipelines, a type of connection called a gap or cap connection is used. These types of connections are produced in different sizes and are used to blind the end of the pipeline and are welded to the pipe.
Elbow joints are used to change the direction of the pipe in the piping process. These connections are produced at 45° and 90° angles and are used when it is necessary to change the piping route at an angle of 45 to 90°. In order to connect these connections, you should put a 90 degree elbow (زانو مانیسمان 90 درجه) or 45 degree elbow between the two pipes and connect the two ends of the connection to the pipe using welding.
Mannesmann transformation fittings
To connect two pipes with different diameters or to change the size of the pipe head, they use fittings called conversion. This type of Mannesmann metal fittings are produced in two models, straight and crooked, and are used in different situations according to their application. Mannesmann conversion fittings are designed so that one end is small and the other end is larger, and it is used to connect a large pipe to a small pipe or vice versa.
This is a piece that can be used to extend and shorten pipelines. It can also be used to connect two small fittings.
Four way connections
The external shape of the four-branch connections, or Manisman's four-way connection, is similar to a cross, and it is used to connect 4 pipes, and finally, with the help of this type of connection, the pipe can be guided in 4 different directions.
Bushen fittings are used to connect two identical pipes at the end of the pipe.
