  • Page 19: Introduction

    21.3 mm to 114.3 mm (0.84 in. to 4.50 in.). The COBRA scanner typically uses the OmniScan (models can vary) with a 16:64 or a 16:128 module, and the OmniScan MXU software to inspect circumferential welds on small-diameter pipes (see Figure i-2 on page 13).

  • Page 20: Figure I-3 Operating The Cobra Scanner In A Limited Access Area

    Specially designed low-profile wedges that fit each pipe diameter covered by the scanner, are also offered to complete the solution. The COBRA scanner ensures stable, constant, and strong pressure thus providing good UT signals and precise encoding around the full circumference of the pipe.

  • Page 21: Cobra Scanner Description

    DMTA-20006-01EN, Rev. B, February 2014 1. COBRA Scanner Description The COBRA scanner is a low profile encoded scanner supporting one or two probes. The COBRA scanner provides a kit of parts that you can easily assemble, thus configuring the scanner to fit on the outside diameter of the pipe to be inspected (see Figure 1-1 on page 15).

  • Page 27: Setup And Operation

    Removing the Probe When ordered as a kit (COBRA-K-XXX), the one or two probes are already installed on the COBRA scanner at the factory. Therefore, when you want to configure the scanner using the setup template, you need to remove the probe from the wedge.

  • Page 28: Installing The Probe

    DMTA-20006-01EN, Rev. B, February 2014 If you need to replace the probe: a) Using the T6 Torx screw driver, remove the sleeve clamp screw, and then slide the protective sleeve and sleeve clamp away from the tail (see Figure 2-1 on page 22).

  • Page 29: Figure 2-2 Installing The Protective Sleeve

    DMTA-20006-01EN, Rev. B, February 2014 Figure 2-2 Installing the protective sleeve Install the sleeve clamp as follows (see Figure 2-3 on page 23): a) Install the sleeve clamp over the bundle and then slide it over the protective sleeve. b) Install the sleeve clamp screw into the sleeve clamp so the threads of the sleeve clamp screw just start to engage in the sleeve clamp (see illustration A).

  • Page 31: Changing The Wedge

    DMTA-20006-01EN, Rev. B, February 2014 Changing the Wedge You need to change the wedge when you inspect a pipe with a different outside diameter. To change the wedge Remove the outer probe-holder arm (see Figure 2-5 on page 25): a) Loosen without removing the probe-holder-arm screw. b) Slide the arm off the probe holder.

  • Page 32: Adjusting The Length Of Exposed Cables And Tubes

    Adjusting the Length of Exposed Cables and Tubes After replacing a probe or reconfiguring the COBRA scanner for another pipe size, you need to adjust the length of exposed cables and tubes. To prevent damaging the probe and encoder cable, always carefully adjust their length to fit the circumference of the scanner posts.

  • Page 33: Configuring The Scanner Using The Setup Template

    Figure 2-6 Clipping the tube and the cable on the post Configuring the Scanner Using the Setup Template You must configure the COBRA scanner for the pipe outside diameter on which you want to perform the inspection. The setup templates offer guiding patterns for a wide range of standard pipe outside diameters.
