Gantry-style material handling system for pipe ultrasonic tester

Gantry ultrasonic tester

THE energy industry consumes an enormous amount of tubular products. Given the strict quality standards, new and used pipes must be thoroughly tested before being used in the field. In the ‘full body phased array ultrasonic’ testing method, several testing attributes are performed at one time, requiring a handling system and integrated controls to effectively position and test a wide range of pipe sizes. Haven Manufacturing has expanded its material handling and systems control knowledge into the oil and gas pipe testing market. In cooperation with ultrasonic electronics producers, Haven has designed a gantry and rail system that will support a full body phased array ultrasonic system. The capacity of this system is from 2.5" to 20" diameter, and up to 48ft length. The sequence of operation begins with measuring the length of each pipe, to determine the end-of-pipe location. A walking beam transfer device then positions the pipe in the test station, while simultaneously removing a tested pipe to an exit table or conveyor. In the testing station, the pipe is rotated at a controlled RPM to match the specified linear speed of the ultrasonic tester carriage. The combination of rotation and carriage linear speed creates the desired test helix pattern for a given pipe diameter and wall thickness. Multiple servo drives control the synchronisation of the test cycle. Manipulating up to 24,000lb of pipe at one time requires both precision and robust construction.
