Internal Line-Up Clamps

To ensure the highest quality of welding, Maats can supply internal line-up clamps designed for precise pipe alignment. These clamps can be powered directly by the welding tractor. Alternatively, Maats also offers air compressors to provide the required compressed air supply. Each internal line-up clamp is delivered complete with the necessary hoses and reach rods, ensuring a ready-to-use solution on site.

External Line-Up Clamps

External clamps are available in several variants — including hydraulic, ratchet-operated, and manual types — depending on the mechanism used to tighten and align the clamp. Applied to the exterior of steel pipes, they ensure precise alignment of pipe ends prior to welding, maintaining correct positioning and roundness while minimising gaps or misalignment at the weld joint. External clamps are particularly effective when internal access is limited or the use of internal alignment tools is impractical.

External Line-Up Clamps

External line-up clamps (ELC) are essential tools in pipeline construction, used to align steel pipes precisely before welding. By ensuring perfect roundness and accurate joint positioning, they help achieve high-quality welds and reduce setup time.

Maats offers a range of External Line-up Clamps for sale only, designed for durability, ease of use, and reliable performance on projects of all sizes.

Compressor Sets

A compressor set plays a vital role in the pipe bending process, supplying the compressed air required to operate the hydraulic systems and the internal mandrel. Maintaining the correct air pressure is essential to ensure both safety and precision throughout bending operations.
