Krautkrämer rot

Increase productivity and reduce operating costs while meeting all regulatory requirements

Krautkrämer ROT is a high-speed full-body tube tester with rotating ultrasonic probes for seamless and electrical resistance welded (ERW) tubes. Krautkrämer ROT comes in a compact package and is designed to be integrated into the production line for online testing. In addition to defect testing, a complete dimensional measurement is also available. Different models are available for tube diameters from 10 to 345 mm (.39 to 13.6 in.) outer diameter.

Full Body Ultrasonic Inspection (FBUI) of tubes starts here

The requirements on OCTG pipe products have been constantly rising due to advanced exploration techniques like hydraulic fracturing or horizontal drilling. Seamless tubes (e. g. for risers or drill pipe) are usually tested for flaws on the outer and inner surface and for inside wall defects. As well wall thickness- and dimensional measurement (GEO) takes place. Waygate Technologies rotary testing machines are the optimum solution to fulfill the required test task on small to medium diameter ranges, representing a compact solution that can be integrated directly into the production process. Beside seamless tubes, electrically welded tubes (ERW) having flash-trimmed weld seams are also tested on rotation units if the later tube application specifies a corresponding test.
