All Components in View – Measure Any Offshore Flexible with Instruments from Zumbach


The production of offshore Flexibles involves complex process’s requiring varying individual performances for quality control. Any deviations from the required standards can risk horrific consequences if failure occurs depending the application scenarios.
In order that the risks for future product failure are eliminated during the manufacturing processes, such as wire drawing, profile rolling / extruding, stranding and sheathing, ZUMBACH provides reliable solutions for the measurement of all critical parameters.

Zumbach has measurement solutions for nearly all wires, cables, tubes and profiles:

Step by step all values under control

From the first seconds of extrusion, ultrasonic measurement systems (UMAC®) with up to eight real measurement points, allow the eccentricity, independently of the material temperature to be measured. Once the eccentricity of the cable is optimized, it comes down to the next stage of maintaining the required average wall thickness and then further to derive the minimum wall thickness limitation. These measurements are typically performed before and after the extruder by ODAC® and UMAC®. An additional measurement of the outside diameter at the end of the line allows the integration of the measured cold diameter value. This allows the determination of the shrinkage, which can thus be fed back within the process to realize optimum configuration.

Similar approaches generate quality improvements in pipe extrusion. At the beginning of the process, the eccentricity of the pipe must be brought under control, then the wall thickness and finally outer diameter as quickly as possible. The optimization of the wall thickness and the monitoring of the outside diameter is also ensured by the combined and cost-effective ultrasonic and laser measurement technology from Zumbach.

Accurate process monitoring and quality control during cable and pipe extrusion

In the extrusion of cables or pipe jackets, UMAC® ultrasonic measurement ensures early notification of product centralization and achieved Wall thickness. UMAC® measures and controls parameters such as eccentricity and wall thickness for up to 5 layers of materials at a maximum of 8 individual measuring points around the circumference. Additional installed ODAC® or MSD® diameter measuring heads benefit by checking the diameter and ovality. Using these technologies, allows the manufacturer to closely monitor the extrusion processes and thus continuously maintain the quality requirements.

Control solutions such as Zumbach’s dual-loop method, as example, takes into account the product properties in both the hot and cold conditions. The resultant reported data is determined from a combination of the diameter measurement using ODAC laser measuring heads and UMAC ultrasonic eccentricity and wall thickness scanners.

Customer project: Stranding


With the ODAC® 63TRIO (3-axis measuring heads) the ovality of a product can be measured very precisely.
The implementation in the manufacturing process is a “vertical” solution with a proposed 18 x ODAC® 63TRIO heads to monitor the ovality of pipes for an offshore product during the stranding process. The finished Offshore product is then measured with a 3-axis ODAC 550 system to ensure outer diameter and ovality specifications are achieved.
