External hydraulic clamps (CNG) are detachable pipe clamps used in the construction and repair of pipelines for centering pipes with diameters from 630 mm to 1220 mm.

Unlike the external link and eccentric clamp, a hydraulic jack is installed on the hydraulic clamp to tighten the pipes together.

Due to the increased compression force and additional screws, the external hydraulic clamps also provide the centering of the deformed pipes.

The design of the clamping units allows continuous welding to be applied.
