What is a welded pipe?
These pipes are among the preferred materials in many fields from heavy industry to construction; they come to the fore with their durability and sustainable structures.
Description of Welded Pipe
Welded pipe refers to pipes made of steel or iron, usually joined by a longitudinal or spiral seam. This joining method improves the integrity and strength of the pipe.
In the production process, it is essential that the metal sheets are made into rolls and their edges are joined by welding method. This process critically improves the resistance of the pipe to internal and external pressure, while maximizing its sealing properties.
In addition, welded pipes are preferred with wide diameter range and strength values, especially in systems that will operate under high pressure.
Construction Process of the Welded Pipe
The production of welded pipes begins when high quality steel strips are rolled and take the form of pipes. During this process, the edges of the strip are boiled at a high temperature. The welding process strengthens and integrates the structure of the pipe.
At the sewing stage, precise techniques are applied to ensure that the edges fit perfectly together. In this process, called ”melting welding”, cleaning the surface from roughness improves the quality of the pipe.
Welded pipes acquire properties that are resistant to very high pressures thanks to sophisticated production techniques.
After that, the pipe goes through the processes of cooling, straightening and cutting to the desired dimensions. Quality control steps eliminate possible errors and ensure that only high standard products are placed on the market. This comprehensive process guarantees the production of pipes that perfectly adapt to conditions requiring high performance.
Types and Comparisons
The types of welded pipes differ according to the material used and the production process. They are produced in various sizes and thicknesses for industrial use.
There are two main production technologies: electrical resistance welding (ERW) and sublimation arc welding (SAW). ERW is suitable for low and medium pressure, while SAW is preferred for higher pressures and thicknesses.
When a comparison is made, it is seen that the production speed of ERW pipes is higher than SAW pipes. However, SAW pipes generally have better mechanical properties and are suitable for use over long distances.
When choosing the most suitable type of welded pipe for a particular project, not only cost and availability should be taken into account, but also pressure, temperature and properties of the material to be transported.
Since quality and sustainability are of vital importance for companies in the construction sector, these criteria should be evaluated as a priority in the selection of pipes.
