The advantage of steel tubes for precision applications is the high precision of their manufacturing, the good quality of their surface, and the guaranteed mechanical and technological properties. That is why the pipes are widely used in the machining industry and in the automotive industry. Welded pipes for precision applications are manufactured in the process of cold drawing.
