How Precision Tube Dies Improve Seamless Pipe Manufacturing
How Precision Tube Dies Improve Seamless Pipe Manufacturing
As demand grows for high-performance steel pipes used in energy, construction, transportation, and heavy industry, manufacturers continue to pursue higher dimensional accuracy, longer tool life, and more stable production processes.
Among the many components used in seamless tube production, the tube die is one of the most important. Although it is rarely visible in the finished product, its design and manufacturing quality have a direct impact on pipe accuracy, production efficiency, and operating costs.
For this reason, precision tube dies have become essential components within modern heavy machinery manufacturing.

In the process of cold pilgering, a billet is placed through a mandrel while one mandrel is fed into and out of the other mandrel with the help of a machine tool. These kinds of movements allow the workpiece to be pushed out with a small change in diameter through deformation of the metal on the inner side. The process is quite slow since it only allows a decrease in diameter of 5-7% per pass but if you need it you can go up to 30%.
There is one type of pilgering which is a special one - it is continuous and it can operate non-stop for several hundred meters of tubing which is very impressive. But this method also has limitations which are mainly due to the very high cost of initial investment.
The cold pilgering method produces a very uniform, round-shaped seamless tube. There are even some specialized tools which can work out a spiral shaped pipe in this way but they are very rare as most applications prefer the shape from cold pilgering.
If it comes down to the technical aspects of cold pilgering, there are many things that have to be taken into account such as the correct choice of the mandrel diameter and material, speed, feed of the machine tool which are the most influential.
