Krautkrämer GRP Gantry
Advanced Ultrasonic Testing for Seamless Pipe Inspection
The Krautkrämer GRP Gantry maximizes quality assurance by detecting all critical defects in a single pass and reducing costly downstream failures and warranty claims, thereby boosting production efficiency and reducing total cost of ownership.
Full Body Testing for Seamless Pipes starts here
Engineered for precision, performance, and productivity, the Krautkrämer GRP Gantry is a state-of-the-art ultrasonic testing system designed to inspect seamless pipes of medium to large diameters. It is particularly suitable for tubing, casing and line pipes used in the oil and gas industry, thus expanding our wide range of Oil Country Tubular Goods (OCTG) testing equipment.

Installed directly in the seamless pipe production flow, the Krautkrämer GRP Gantry ensures early-stage quality assurance, reducing downstream failures and warranty risks. Its modular design and scalable electronics make it a future-proof investment for manufacturers seeking reliability and efficiency.
The Krautkrämer GRP Gantry leverages advanced Phased Array ultrasonic technology to detect all critical internal and external wall defects. In addition to the common longitudinal, transversal and lamination flaws, oblique flaws in all standard angular orientations up to 67° can be inspected. A parallel evaluation for wall-thickness deviations completes the inspection scope. As natural flaws do not always exactly follow the angle orientation defined by norms and standards, the optional gapless inspection capability can identify all oblique flaw orientations in between the defined discrete angles without any additional effort. This significantly reduces the risk for upcoming customer claims due to allegedly missed flaws.
Its gantry-style architecture positions probe clusters above the pipe, enabling full-body inspection while the pipe rotates in place. Thanks to this bridge-style gantry construction with an adapted free length between pillars, the system supports crosswise pipe transport, significantly reducing the overall footprint and simplifying integration into existing production lines. This configuration ensures high-resolution flaw detection without the need for complex, space consuming and slow helical tube transportation systems.
