Oxygen Lancing Tube
To transfer these gases to the molten metal, a pipe is needed. This pipe is the lancing pipe and the process of injecting gases into molten metal is known as lancing.
Precision tubes for production of bearings
Precision tubes for production of bearings use the cold drawing process. Rolled seamless tubes are used as the semi-finished product.
