The series of internal line up clamp of LOYANG DEPING TECHNOLOGY CO., LTD is specially developed for cases when the welding technology foresees the formation of the root of the seam using a copper shoes.

In the design of internal line up clamp, only high-quality, reliable components of world famous manufacturers FESTO, Ingersoll Rand and others are used, which ensure high reliability, uniform distribution of edge misalignment along the joint perimeter and guaranteed integrity of the inner coating of pipes.

The application of the internal line up clamp of LOYANG DEPING TECHNOLOGY CO., LTD allows to mechanize the assembly operation more fully. In addition, the assembled joint is completely accessible for welding, and the root seam can be performed from start to finish without stopping and stitches. The payback period of this type of line up clamp is reduced by saving time in welding the pipeline into a thread and improving the quality of the welded seam. In contrast to external centralizers, the use of internal line up clamp provides full access to the weld seam. This is most important for large pipe diameters and when welding machines are used. The internal line up clamp of this series are specially designed for the centering and welding of pipelines from high-alloy (including stainless steels), duplex steels, iron-nickel alloys, and double-layer steels.
