Tubular inspection services and equipment TUBOSCOPE, a division of National Oilwell Varco, LP (NOV), is a supplier of tubular inspection services and equipment to the petroleum and pipe manufacturing industry. Its technologies are used for inspecting new and used tubular goods to demanding industry and customer specifications, and include Amalog ® and Sonoscope ® electro- magnetic inspection (EMI) technologies, and Truscope ® , TruWall ® and TruScan ® ultrasonic (UT) inspection systems. is introduced into the pipe. Multiple stationary detector assemblies, or ‘shoes’, are brought into contact with the outside diameter pipe surface. Flaws such as transversely orientated cracks, rolled-in slugs and pits are detected by this inspection method. The pipe is next conveyed through the Amalog inspection unit, which is equipped with a dual-shoe detection system integrated into a rotating mag- netiser assembly. As the pipe enters the Amalog inspection unit, a high-strength active magnetic flux field, circumferen- tially orientated, is introduced into the pipe. The rotating detector shoes then scan the outside surface area of the pipe circumferentially in a helical path. Flaws such as longitudinally orientated seams, cracks and overlaps are detected by this inspection method. Tuboscope – USA Website: www.nov.com
An example of the capability within the Tuboscope product line is the Truscope A/S (Amalog-Sonoscope). This inspection system combines the non-destructive techniques of EMI and UT principles to detect, evaluate and classify, in a single pass of the pipe through the system, transverse and longitudinal, internal and external flaws as well as wall thickness variations and laminations. The Truscope A/S system provides full-body inspection across a large range of pipe diameters. The pipes can be seamless or ERW; manufactured of ferrous or non-ferrous alloy materials; and with a variety of end conditions – saw-cut or cropped, plain-end, threaded, coupled, and upset or non-upset. With its combination of EMI (Amalog and Sonoscope) and UT (Truscope) techniques, the Truscope A/S satisfies the latest editions of API 5CT, 5L and 5D, as well as numerous other international specifications for non-destructive inspection of tubular products for the energy industry. The inspection system comprises two main sections – the inspection platform and the computerised inspection electronics. Placed within a pipe conveyor line, the pipes are advanced to the inspection platform. Mounted on this platform are pinch rolls that contain the pipe and provide the driving power to move it at a constant speed though the three individual inspection heads, or positioners. The testing sequence is the Sonoscope first, followed by the Amalog and ending with the Truscope. All three positioners are mounted on track roller systems to allow them to be moved in or out of the conveyor line for pipe size change-over or maintenance. Pipe to be inspected is first conveyed through the Sonoscope inspection unit, where a high-strength active magnetic field orientated longitudinally
straightening for diameters from 5 to 220 mm
straightening machines for precise straightening of round tubes
For each process the right system • Automating e.g. separating and handling systems • Straightening e.g. 2-, 6- and 10-roll-straightening machines • Inspecting e.g. complete NDT inspection lines and straightness measuring • Sawing
e.g. multi head cut systems
• End Finishing e.g. deburring, thread cutting, punching • Packaging e.g. bundling and packaging into round, square and hexagon bundles
