External pipe centering: Precision and efficiency for welded joints in pipeline construction

The pipe centring device for precise welding is the ideal solution for minimizing edge misalignment on pipe joints. It is placed over the pipe joint and exerts stable pressure on the pipe ends using a hydraulic cylinder or mechanical force. With a hinged double ring and adjustable centering bridges, it enables up to 90 % of the welding work on the root layers to be carried out without removing the centering. Available in hydraulic and mechanical versions, it offers maximum flexibility for pipeline construction and other industrial welding applications.

Detailed product description

Precision and efficiency for pipe connections

The pipe centring device is placed over the joint of two pipes and minimizes edge misalignment through controlled pressure. The hydraulic cylinder of the most powerful version generates up to 5 tons of pressure, while mechanical models work with stable screw connections. This ensures precise weld seams and stable connections – indispensable in pipeline construction and industrial welding work.

The external pipe centering device is available in different versions. Medium-duty models are made of round tube, while the heavy-duty version is reinforced with flat material. These designs guarantee durability and stability, even with intensive use.

Easy handling and fast operational readiness

The external pipe centering tool impresses with its user-friendly design. Thanks to the hinged double ring and the adjustable centering bridges, the tool can be quickly and easily adapted to pipe diameters from DN 80 to DN 1600. These features make it the ideal choice for pipeline construction projects where the focus is on efficiency and time savings.

Flexibility with different pipe diameters

Whether small or large pipe diameters – the external pipe centering system offers a flexible solution. Thanks to the versatile variants, pipes from DN 80 to DN 1600 can be used. This makes them indispensable for applications in piping and welding technology where precision is required for changing requirements.

High level of occupational safety during welding work

A safe working environment is essential, especially in industrial piping construction. The precise alignment of the pipes minimizes edge misalignment and reduces the risk of errors or accidents. The robust design also ensures a firm hold during the entire welding process – regardless of whether hydraulic or mechanical models are used.
