Effective handling and ultrasonic testing of oil and gas pipe

A walking beam transfer device positions the pipe in the test station, while simultaneously removing a tested pipe. In the testing station, the pipe is rotated at a controlled rpm to match the specified linear speed of the ultrasonic tester carriage. Multiple servo drives control the test cycle synchronization, while manipulation of up to 11,000kg of pipe at one time requires both precision and robust construction. Haven’s reputation for dependable design and superior quality has been transformed from its standard tube cutting and tube finishing products to an industry that demands ultra-reliable performance. In addition, the company has also been involved with pipe end-to-end manipulation for ultrasonic testing. Haven Manufacturing Corporation – USA Fax : +1 912 264 9001

Haven Manufacturing Corporation, USA, has expanded its material handling and systems control knowledge into the oil and gas pipe testing market. The company is a worldwide leader in integrated tube processing systems.

In cooperation with a leading non- destructive test company, Haven has designed a gantry and rail system that supports a full body phased array ultrasonic tester. The capacity of this system is from 64-535mm diameter and up to 15m long.

Automated non-destructive testing systems NDT Technologies Inc, Canada, is the manufacturer of a range of automated non- destructive testing systems, precision measuring and material handling. The company has launched a new device for offline detection of internal and external flaws in automotive engine cylinder liners. The system uses the eddy current flaw detection method for the detection of micro- cracks, surface imperfections and sub-surface flaws. Defective parts are diverted to the reject chute. Typical test cycle in production factory is less than 15 seconds. NDT Technologies has also introduced an automotive hollow shaft flaw detector. The Eddytron TM is designed to inspect aluminium steering column casting for internal surface flaws in the body, and in the hydraulic seal seat chamber. The casting is used for power steering applications in automotive industry. Due to the operational importance and highly complex geometric shape of the cast part, stringent quality control parameters need to be implemented. The system provides electronic evaluation of changes in eddy currents (due to imperfections) that are present on material surfaces. The method is sensitive to changes in distance between the probe and the material, requiring a high level of manufacturing precision on the probe guidance system. Flaws as small as 0.2mm deep can be detected. In order to achieve test consistency, the system is supplied with calibration specimens that contain artificial flaws of known dimensions. The calibration specimens are used to

set the test base line sensitivity. NDT Technologies Inc – Canada Fax : +1 514 457 7652 Email : info@ndt.ca • Website : www.ndt.ca
