A length compensator for pipelines, preferably plastic pipelines, containing two connecting components, preferably made from plastic, a compensating element made from an elastic material, preferably a thermoplastic elastomer (TPE), and a supporting pipe, wherein the compensating element is arranged between the two connecting components and the compensating element ends are connected to the connecting components, wherein the outer lateral surface of the compensating element is suitably encompassed by the inner lateral surface of the supporting pipe around its entire circumference, wherein the supporting pipe has a circular cross-sectional area and the compensating element expands and contracts exclusively in the axial direction.

Length compensator

Method and device for tightening a threaded connection, preferably for connecting pipeline components, wherein the threaded connection to be tightened comprises a connecting element unit having an external thread, a connecting element unit having an internal thread, and a seal element arranged therebetween.

Installation method and device for pipeline components

A technique for sensing a weld seam geometry of a plastic butt weld seam, preferably plastic pipes, including:

Method for detecting weld seam geometry

A device for fastening a measuring apparatus on pipes, in particular a butt weld seam checking measuring apparatus, containing a housing for accommodating the measuring, control, and/or drive units and a clamp, wherein the clamp is designed as a ring segment, wherein the clamp is attached in the radial direction over a pipe external diameter, wherein the clamp has a pre-tension in the installed state.

Fastening device for measuring apparatuses on pipes

A device for the contactless examination of a butt weld of plastic pipes and fittings is provided. The device includes a carrier device, an illumination unit, and at least one sensor for monitoring the pipe ends or fitting ends to be welded and the weld seam, wherein the sensor is an electronic light-sensitive sensor.
