New/Used Drill Pipe Inspection

     

1)  Visual Tube

·         Full length visual examination of the inside and outside surfaces of used tubes

·         Evaluating Straightness, mechanical or corrosion damage, debris such as scale or drilling mud

2)  OD Gage Tube

 

·         Full length mechanical gauging of the outside diameter of used drill pipe tubes

·         Evaluating Diameter variations caused by excessive wear or mechanical damage, expansions caused by string shot, reductions caused by over pull.

 

3)  UT Wall Thickness

  ·         Wall thickness is measured around one circumference of the drill pipe tube using an ultrasonic thickness gage

·         Evaluating Tube wall thickness below the specified acceptance limits, minimum cross-sectional area of the tube.

 

   

4)  Electromagnetic – 1 (EMI – I)

 

·         Full length scanning (excluding upsets) of drill pipe tube using the longitudinal field (transverse flaw) buggy type unit

·         Evaluating Flaws such as fatigue cracks, corrosion pits, cuts, gouges, and other damage that exceed the specified acceptance limits

      

 

5)  Electromagnetic -2 (EMI –II)

·         Full length scanning (excluding upsets) using a unit (Four function system) with longitudinal magnetic field EMI (transverse flaw), transverse magnetic field EMI (longitudinal flaw), grade verifier and Hall effect system for measuring wall thickness capabilities

·            Evaluating Flaws such as fatigue cracks,    corrosion pits, cuts, gouges,

       reduction of wall  thickness, other damage that exceeds the

       specified acceptance limits and grade  verification.

      

 

6)  MPI Slip/Upset

 

·         Examination of the external surface of drill pipe and HWDP upsets and slip areas using the active-field AC yoke dry /wet magnetic particle technique.

·         Evaluating Flaws such as fatigue cracks, corrosion pits, cuts, gouges, and other damage that exceed the specified acceptance limits.

 


 

7)  UT Slip/Upset

·         Examination of Drill Pipe and HWDP upsets and slip areas using shear wave ultrasonic equipment.

·         Evaluating Flaws such as fatigue cracks, corrosion pits, cuts, gouges, and other damage that exceed the specified acceptance limits.

 

 


8)  Visual Connection

·         Visual examination of connections, shoulders, and tool joints and profile check of threads, measurement of box swell

·         Evaluating Handling damage, indications of torsional damage, galling, washouts, fins, visibly non-flat shoulders, corrosion, weight/grade markings on tool joint and pin flat.

 

9)  Dimensional – 1

·         Measurement or Go-No-Go gauging of box OD, pin ID, shoulder width, and tong space

·         Evaluating torsional capacity of Pin and Box, torsional matching of tool joint and tube, adequate shoulder to support makeup stresses, adequate gripping space for tongs

10)           Dimensional – 2

·         Dimensional - 1 requirement plus measurement or Go-No-Go gauging of pin lead, counterbore depth, box counterbore, pin flat length, bevel diameter, seal width and shoulder flatness

·         Evaluating Same as dimensional - 1, plus evidence of torsional damage, potential box thread engagement with pin flat, excessive

       shoulder width, sufficient seal area to avoid galling,

       non-flat shoulders.

 

11)           Black light Connection

·         Fluorescent wet magnetic particle inspection using active DC current.

·         Evaluating Fatigue Crack.
