Welded tubes have an inherent weakness in the area of the seam, so seamless tubes have to be used for applications with high safety requirements. These tubes are manufactured by penetrating a solid rod with a piercing plug before the tube is drawn down to its desired size.
Piercing plugs from PLANSEE made of TZM yield perfect results with special-alloyed steels as well as in the production of copper tubes. They are far superior to conventional piercing plugs made of special-alloyed steel.
