Pipe Welding Rollers

Pipe welding rollers and rotators are used for clamping, rotating, and tilting of pipes with round profiles in manual and automatic welding, mainly in the field of pipe construction (prefabrication and assembly on site) and central heating construction.
This System can be applied for clamping and rotation of pipes with round profiles, especially in welding. These machines have essential advantages over traditional devices:

• They can be used for pipes with elbows, tee pieces or other offset loads.
• A wide range of pipes can be clamped. The infinitely variable rotary speed is not affected by the size of a pipe because of its separate drive unit.
• Quick precise centering and clamping without chuck, clamping shoe, etc.
• Flexible pipe handling pipe can be clamped at its centre of gravity. Tilting moments and supports are irrelevant in most cases.
• It is possible to center two pipes with the same outside diameter.
• Various combinations are possible - e.g. clamping and driving of a main spindle Some examples for application

Standard pipe rota tors are designed to rotate work pieces 360° with forward and backward title from horizontal. Rotation and tilting may be performed independently or simultaneously. The tilting section consists of the drive and roller box, holding column, clamping arm, and pressure roller. Manual vertical height adjustment of the clam ping roller system is included as standard on all units.

DESCRIPTION
The electric control as well as the tilting drive are located in the frame. Tilting is carried out manually (U 150 and U 500) or motorized (U 1000, optional U 500) the tilting angle is approx. 135°. The tilting section consists of drive and roller box, holding column, clamping arm and pressure roller. This machine is also available as a nontilting version (designation: U 150H, U 500H, U 1000H). In general, drives and electric controls of the U-series are protected in the frame or in a control panel. ELECTRIC CONTROL Rotary speed and direction are set at the front of the machine which is switched on and off by a remote foot switch. Further options of electric control:

a) Separate foot operated control unit (see illustration U 500, photo on this page). Switching on and off and changing the direction of rotation takes place by a foot switch, the rotary speed is adjusted by a foot control roller.
b) Switching on and off as well as changing the direction of rotation is carried out from the welder’s helmet or shield. The rotary speed is set at the machine.
c) Turning direction and turning speed are set on a remote hand pendant.
