When choosing 20G alloy steel tube to work, we usually doubt its quality, because good quality 20G alloy steel tube is of great help to the work, and before the choice, we should be clear about what factors will affect the quality of 20G alloy steel pipe, what is the main influencing factor?
In the entire use of 20G alloy steel tube, we can find that the quality of the billet directly determines the quality of 20G alloy steel tube. For the size of the tube billet, its organization and the state of its surface must have more stringent requirements, so as to ensure the correct use of 20G alloy steel tube.
If the diameter of the tube billet is very large, or its ellipticity is too large, it will lead to damage in the perforation. Because the compression of the tube billet is too large, it will also occur infolding phenomenon, which affects the quality of 20G alloy steel tube.
