A large multi-test ultrasonic/ eddy current system has been installed at the Interpipe NTRP steel tube rolling mill in Dnepropetrovsk, Ukraine.

This MAC system includes a 10 channel Echomac® ultrasonic FD-4 and rotary to inspect for longitudinal and transverse defects and measure dimensions and wall thickness. Also included is a MAC 250 eddy current equipment to detect short surface defects, a Production Comparator to check steel grade, and a Demagnetizer to remove residual magnetism.

The automated test system is mounted on a large test bench which includes a slide and elevate mechanism, coil platforms, and drives. MAC also supplied a complete recirculating water package and water chiller for the ultrasonic inspection test, and a bar wash to prepare the tube for testing. The system is designed to handle tube ranging from 1/2" to 6" diameter (12.7 mm to 152.4 mm).

Installation of this system, along with a pipe end inspection test, enables NTRP to provide full non destructive testing of its steel pipe products, thereby improving its offering to customers.
