NDT test systems for tube and bar on display at Tube India 2022

tube mill. This new system is uniquely able to measure the tube profile and monitor the scarfing trim tool operation in the heat affected zone, often within 40ft of the welder, at temperatures up to 252°F (122°C). This upstream location in the weld line gives the operator instant feedback when the scarfing tool is bad or broken, allowing immediate adjustment of the welding operation and saving many feet of would-be tube scrap. Real time B and C-scan views of the quality of the weld and seam-trim tool alert the operator to issues such as undercuts and other failures with the scarfing process. High PRF can be used based on thickness to get a detailed weld profile with high resolution and no averaging or AGC is used for processing the data. A key feature of this system is the minimal operator intervention during operation. The wide coverage of the test head can handle typical shifts in the weld location, and the electronically con-trolled transducers can vary the pulse timing of the individual elements to inspect with multiple angles, if needed, all without any manual intervention. Installation can also be in a lower temperature area below 140°F (60°C) for ID/OD longitudinal flaw detection and profile monitoring, after the forming and shaping operation.

NDT TEST instruments and systems for inspecting tube, pipe, bar and wire will be featured at Magnetic Analysis Corp and Inmar Engineering Corp’s Stand J97 at Tube India 2022 in Mumbai, India. Highlights of the booth will be a demonstration of the Minimac ® eddy current tester inspecting small diameter tube and information on MAC’s latest Echomac ® phased array ultrasonic systems for testing ERW welded tube. The Minimac 50/55 for inspecting wire, rod and tube for short surface and some subsurface defects at speeds up to 4,000fpm will be on display at the booth. This eddy current instrument is frequently used for inspecting welding wire, including flux core wire where it can detect missing flux as well as flaws in the wire itself. Finding weld-line faults in tube and checking continuity in single and multi-conductor insulated wire and cable are other applications. Using an MID option, the Minimac is also very effective for detecting magnetic inclusions in non-magnetic product. MAC’s MultiMac 8 channel eddy current instrument is widely used to detect surface defects and laps in cold drawn wire and high-speed operations. Information will be available on MAC’s Echomac PA TW Phased Array UT Robot system, installed recently at a US

Echomac UT Phased Array Robotic system for testing ERW tube and pipe

MAC also has an online ultrasonic Weld Zone Test system at a major Indian tube producer where it is inspecting large diameter ERW tubes for hydraulic cylinders, used in safety critical mobile equipment. Information on the Echomac 25mm UT Rotary, which is designed for high performanceapplications suchas tubular product for nuclear and aerospace installations, will also be available at the booth. This full body test equipment provides 100 per cent coverage at high throughput rates on product ranging from 5 to 25mm diameter. The 630mm overall length of the Rotary allows for ease of installation when upgrading existing inspection lines. Wall thickness as thin as 0.4mm and tubes as short as 1.2m can be successfully tested. The local remote pulsar/receiver allows high gain but provides low susceptibility to mill electrical interference, and wide band width transformer signal coupling allows selection of any transducer frequency from 5 to 17MHz. The 25mm Rotary joins MAC’s line of UT Rotaries which range up to 500mm capacity. MAC’s Echomac FD-6/6A instrumentation, is available for use with the 25mm Rotary providing outstanding inspection of ID/OD, longitudinal and transverse flaws, wall thickness and dimensional evaluation including conditions of eccentricity and ovality. The Echomac Model 6A holds GE Qualification for P3TF31 and P29TF82 Class A and B, typically required to meet high level quality standards for aerospace and other critical applications.

Reduce down time while cutting with your tube mill RANDOLPH Tool vertical and horizontal tube cut off blades, as well as jaws/dies, are manufactured with tooling processes by craftsmen with an eye for detail and a reputation for ensuing that the blades are perfectly flat and smooth. The blades, being flatter and smoother, cause less friction during the cutting process, which in turn makes the tooling last longer. The longer tooling lasts, the less down time you will have on a tube mill, which means more production time on the mill. The blades lasting longer will also mean spending less on a tooling budget. Blades have the potential to last longer by adding coatings, which are available to best suit the material that is being cut.
