Manisman pipe with a history of more than 130 years in the field of industry was first proposed by Reinhard Max Manisman as a revolution in the pipe production industry and to his father’s sheet metal factory. These pipes were patented in 1885 and in 1886 seamless pipes were produced for the first time.
In 1890, the Mannesmann brothers used the roller process in production, which brought a good sales prospect based on economic success. The combination of the roller process and the bending process with a very fast acceptable sales prospect became famous in the world as the Mannesmann process. This process brought good potential in many fields of technology, a revolution in engineering, piping, vehicle industry for decades.
From the beginning, mannesmann products were produced in different regions of the country in Germany and abroad scattered in the world. In 1899, the first compressed gas pipe production line was launched by Manisman Pipes in the Caucasus, and after that, more shipments of this pipe were used in the branches of water supply systems, piping, and modern street lighting systems all over the world. .
How to produce Manisman tubes
The production of these pipes is done by roller and centrifugal method. First, the molten steel ingot flows into the rotating molds, and due to the fluidity of the molten steel and its high adhesion, in this case, the molten material sticks to the wall, and at the same time, freezing is also done.
Another method of producing Mannesmann pipes is to use a mandrel, which first heats the steel ingot in the furnace, and then the mandrel, which first heats the steel ingot in the furnace, and then the mandrel is fired into the ingot, after that the cooling stage by Water is applied, and finally, warping and polishing operations are performed to make it smooth and uniform. In the following, you will get to know the classification of these pipes…
Manisman pipes are generally classified into 3 categories:
1- Based on thickness and ANSIB 36 and APL 51 standards
2- Based on ANSI standard
3- Based on weight, which includes standard weight STD, heavy XS and extra heavy XXS.
Application of Mannesmann tubes
Manisman pipes have more strength and resistance than seamed pipes, and its widely used grades are 20, 40, and 80, and Manisman grade 20 pipes are used in gas supply pipes in construction and piping systems of motor homes. is used
Difference between Mannesmann tube and other tubes
The first and most important difference between Manisman pipes and other pipes is their production process, in such a way that Manisman pipes are seamless, but other pipes are welded, that is, it is done in the form of sheet cutting, which is done through welding at the end. Shaping happens.
The second difference is in the amount of resistance and pressure, which is much higher in Manisman pipes compared to other types of pipes.
The price of Manisman pipe
Manisman pipes are of higher quality than other pipes, and also the way of producing more screen than other pipes are the reasons for increasing the price of this product compared to other pipes.
