Bent tubes
Le Guellec Tubes & Profiles has recently taken over Procintre in order to extend their production capabilities in bending & machining operations.
The different qualities of bent tubes
2D, 3D bending
The rolling of tubes with large bending radius is carried out on a bending machine with 3 rollers.
The 3D bending involves the cold bending, hollow by winding and with a mandrel.
Spiral tubes
The precision necking is made on a 6-pass horizontal press with turning punches.
Bent tubes with shaped ends
Possibility of shaped ends : flared, reduced, flange
Possibility of nozzle ends : crimped, brazed or welded
The dimensions of bent tubes
Outside diameter : Mini : 1,00 mm – Maxi : 42,00 mm
Wall thickness : Mini : 0,10 mm – Maxi : 3,00 mm
Alloy grades : Low carbon steel, Nickel alloys, copper, titanium etc…
