In our company we use vibratory plastering equipment mostly in combination with ceramic plastering bodies of various shapes and sizes.

Straightening

Tube straightening is a technological forming process that changes the shape of a semi-finished product by external forces without the formation of chips.

In our company we use a straightening stool for cold forming. The tube is stretched between three pairs of mutually inclined straightening rollers, the tube is moved by the first pair of rollers, while the other two pairs balance the tube.

Uses:

• When straightness of pipes is required
• For pipe alignment after heat treatment

Marking and engraving

Marking and engraving is used to identify the required parameter (e.g. material quality, part number, date of manufacture, etc.) or for specific customer requirements (e.g. marking the position of the weld joint).

In our company we use the following methods for marking and engraving:

• Laser engraving (on CNC lasers during production or engraving of the final part on the engraving machine)
• Ink injection marking in continuous tube and steel production
