Coating Identification
Magnet Orientation on a ECD tool is?
NSSN, North South South North
What contaminates have to be considered before cleaning an ILI tool?
LSA, HG, pyrophoric dust, etc.
What is the main discriminators of PU?
Shape/Type and Hardness
How does one identify and verify components or parts?
SAP
PN
Dimensions
What angle of shear wave do we want to achieve for ultrasonic crack detection?
What angle will be applied to get the 45 degree shear wave?
45 Degrees
It depends on the velocity.
What information is critical for UCD carriers.
The angle of incidence.
The size.
If the top two answers are not listed then the part number needs to be readable.
The two main parts of a transportation system is?
Mounting Frame (roller tray or transport tray)
Insertion Frame (Launch Frame)
How does one apply Loctite on a blind hole?
Apply it to the internal threads starting at the top all the way to the bottom of the hole.
Higher attenuation means _?
Lower attenuation means_?
Lower amplitude
Higher amplitude.
Give me three examples of key pipeline components or installations.
Valves, Tees, Bends and Launcher or Receiver traps.
What way do UCD carriers face?
What about UTD carriers?
What is the angel of incidence influenced by?
CW and CCW, CW faces right in the direction of run.
Upstream and Downstream.
Pipeline Medium and Temperature
What type of tools should not be used with torque wrenches?
Angle pieces, universal sockets or flexible extensions.
What is a reason to notch PU? (Trainer give this as a multiple choice.)
Allow bypass over the cup.
Reduce friction.
Reduce wear on the cup.
To seal in the pipeline.
All of the above.
Why do we use Nitrogen for our electronic segments?
To exchange humid oxygen for dry inert N2 gas.
The standard max operating pressure for EMAT tools is?
150 Bar.
What is the sample interval for an EMAT tool?
What about for a UCD?
5mm
2mm
Which of the following are cleaning tools the use bypass nozzles and heavy duty magnets.
ACT
HDC
What influences the decision to reuse a multi diameter cup.
Distance
Wear Behavior
Flow speed of the pipeline.
What type of wave (acoustic mode) is used for UCD tools?
What about for UWD?
Shear Waves
Compression waves.
What are the three types of line pipe?
Longitudinal welded pipe or long seam pipe.
Spirally welded pipe.
Seamless pipe.
What type of defects do EMAT tools detect the best?
Long seem, cracks or axial (linear) defects.
What are the rules for installing a lock nut.
At least 3 threads must protrude out of the nut. As rule of thumb: The screw should not protrude more than 2x thickness of the used locknut. They should not be reused.
What are the functions of PU?
Sealing
Stabilizing and carrying
Scraping or pushing debris
All of the above.
When lifting a tool with slings or chains, what is the maximum angle for the use of vertical slings or chains?
60 Degrees
