The Place to be…Tube & Pipe 2010- Dusseldorf Germany
Since 1988, MAC’s presence has been a constant at the infamous “who’s-who” of NDT trade shows. Messe Dusseldorf’s Tube & Pipe 2010, located in Germany is soon to arrive with its vast list of companies competing for the best displays, best table tops, best locations…etc.
This year, MAC will be in Hall 4/Stand 4H19 and you won’t be able to miss it. Demonstration units including the Echomac® FD-4 Ultrasonic Rotary and electronics as well as the MultiMac® eddy current tester with various coil configurations and electronics will be available along with MAC literature and knowledgeable field staff to answer any questions you may have regarding a MAC solution to your application.
MAC does it Again…
 MAC brings 2009 to an end with one of the largest and most intricate systems in the company’s 80+ years of history. This system also provides MAC with yet another landmark- it includes the Echomac® 360mm UT rotary; the largest US made ultrasonic rotary in the industry.
This system covers a combination of Rotoflux® transverse (TFX) and longitudinal (RFX)flux leakage test systems for detecting longitudinal or transverse defects on the OD or ID of heavy wall seamless pipe up to 14” in diameter. A demagnetizer is used to remove any residual magnetism. In addition to the flux leakage testers, a UT rotary system is also included to provide 100% wall thickness measurement and detection of lamination defects within the wall.
The pipe under test is driven through the test stations by a V-roll test bench at speeds up to
1 meter/second. The pipes are fed into the test bench while centered at all times. This system is one of many MAC systems that meet the API 5CT and 5L requirement for testing OCTG pipe.
Full automation is accomplished via the Conductor Control System; a master computer that works in conjunction with a PLC to control the test bench, integrate data from the test heads, and provide accurate output for downstream operations and marking. Working with the computer is very straight forward using a logical menu structure. The PLC organizes the control of the mechanics and when a new dimension/test is necessary, the computer loads all the information to the test electronics and then changes all the mechanical settings as well as the electronics testing parameters automatically. Electronics include the 48 channel TFX, 24 channel RFX, and 32 channel FD-4.
Success for MAC’s UT Rotary System
 As metal manufacturers and fabricators in the US struggle to compete with lower costs from overseas, they turn to MAC’s fully automated systems that reduce the quantity of rejected material while cutting back on down time and increasing quality.
An example of such a system is MAC’s 125mm UT rotary for stainless steel bars up to 5” in diameter. This system is comprised of several transducers for shear wave configurations to detect surface and subsurface defects and longitudinal wave configurations to detect internal defects and dimensional measurements such as wall thickness. The 7 channel Echomac® FD-4 electronics is also included (up to 32 channels may be accommodated). Each channel tracks a nonconforming condition you wish to detect based on the characteristics of the material.
The system is complete with automatic markers, water system, slide and elevate mechanics for the rotary and large inlet and outlet conveyors at 24 feet each with accept/reject pockets. The entire system is controlled by a central power cabinet which houses the AMFT and PLC, thus completing full automization.
Mobile Test Unit Featuring MAC Equipment
.JPG) Even though Accurate NDT is new to the industry, the owner Kelly Diamond contributes over 37 years of experience in a range of NDT applications. Accurate has a mobile test trailer that features a 7 channel Echomac® ultrasonic rotary, Echomac® FD-4 electronics, the Multimac® eddy current electronics with an encircling coil, pinch stands, and a complete water recirculation system.
MAC’s equipment primarily detects ID/OD defects; surface, subsurface, and internal defects; short and long continuous defects; and wall thickness and measurement, among others. Besides MAC’s wide range of flaw detection capabilities, Accurate also provides C-scan, magnetic particle testing, dye penetrant, and radiography inspection.
The Accurate NDT option is a smart solution for domestic manufacturers of small diameter (up to 2”) bar and tube who do not want to invest in their own test equipment. Accurate also supplies training for inspectors at the companies it services. For more information, email: andts_inc@yahoo.com.
For larger, more demanding domestic manufactures of metals, MAC has a testing facility located in Boardman Ohio that can receive and ship nationally. For more information, please visit our website www.mac-ndt.com or email contactus@mac-ndt.com
