Tube bending into half-sphere (or tube closing, tube rolling) is a special processing made to have a sphere at the end of the tube.

Bending of cylindrical tubes require the aid of cutting-edge machinery to keep pace with the times.
The continuous growth of and demand for tube cambering has led the company to invest in this sector, thus expanding the possibilities for different mechanical processes.

Tapering is the act of gradually reducing or widening the tube diameter, its shape for a certain length, whereas smaller extensions are used for tube flaring and tube flanging.

This processing is usually known as squared tube swaging (as far as the cross-section of square conified tubes is concerned).

Swaging the tube into a conical shape involves the reduction of its diameter, by keeping 
this decrease constant throughout the required length and, hence, obtaining conical tubes.
