|The renowned Turkish tube mill Kalibre Boru receives an ECHOGRAPH-HRPR tube testing system from KARL DEUTSCH. Kalibre Boru was established in 1978 and currently has 500 employees. A key market for their seamless and welded precision tubes is the automotive industry and therefore, ultrasonic testing is an important test procedure for quality assurance.
Operations director Mr Aytaç Ünlü is responsible for the project and placed the contract with Mr. Peter Schulte, responsible for the sales of ultrasonic testing systems at KARL DEUTSCH. The ECHOGRAPH-HRPR testing system is a well-established concept for the high-speed inspection of seamless and ERW-welded tubes. The pipes are transported in a linear manner through rings of ultrasonic probes within an immersion tank.
For the respective project, two probe rings for the detection of longitudinal defects are applied: The first ring contains probes which transmit sound clockwise into the pipe. The second ring transmits sound counter-clockwise. Both rings ensure full coverage of the testing volume. The probes are mounted into cassettes which must be designed in accordance with the pipe diameter. The diameter range between 40 mm and 120 mm can be inspected by using two cassettes. The conveyor systems and the test table is provided by the German company sema Systemtechnik GmbH & Co. KG which is a leading international manufacturer of machines and systems for the semis industry and packaging technology.
The challenge for this testing line was the end-to-end transportation of the tubes. This ensures a high throughput and short untested ends. Our Turkish sales partner, the company Teber Kalite from Bursa-Nilüfer is providing the local support and Yasar Aytaç as the managing director is a well-known NDT specialist in Turkey.
