BOSSI

Tube and closed profile production line for black and stainless steel tubes with diameters from 20.0 mm to 70.0 mm and wall thicknesses from 0.5 mm to 3.5 mm. Other diameter ranges can be manufactured upon request by producing an appropriate roller set.

The tube or closed profile is formed by roll-forming a steel strip of suitable width and thickness using a roller assembly, followed by TIG welding. During production, the tube undergoes a series of further processing steps such as:
a) weld seam grinding
b) calibration
c) straightening
d) and cutting
The finished "raw tube" is then subjected to further surface treatment to achieve the desired surface finish. Two finishing processes are available:
a) wet grinding using coated abrasive belts
b) and/or dry polishing using polishing wheels and compounds.

CONSTRUCTION
The tube mill is equipped with automatic TIG welding from SAF:
a) 2 x Tricathode Inverter NERTAMATIC 300 TR TIG
b) 1 x Tricathode Inverter NETRINOX TH 500 TIG
c) E16 torch for welding tube wall thickness 0.5 - 1.5 mm
d) E25 torch for welding tube wall thickness 1.5 - 3.5 mm
e) RETRISAF cooling system
