threaded region ultrasonic phased array inspection solution

 

 

overview

Relevant circumstances to be seized artifacts:

Casing is mainly used for drilling and completion of the right wall of the support, to ensure that the conduct and completion of the drilling process after the normal operation of the wells. Threaded region due to stress concentration, are more prone to fatigue cracking, resulting in damage to the well.
The program intends to adopt ultrasonic phased array inspection technology to accurately detect small defects and positioning

 

Selection of instrument, probes, wedges

1. Instrument: Doppler----PHASCAN 32/64

 

  1. Phase array cobra probe: 10S16-0.5*10-TY BFB529-TY;

Inspection method­­­

 

Adopt with 10S16-0.5*10-TY BFB529-TY match with different curve wedge in testing threaded area by ultrasonic phase array testing method.

 

1:Illustration image of threaded area circumferential defect detection:

 

                   Cobra probe position in longitudinal defect detecting

 

Scanning mode: the probe along the circumferential direction of the tube as jagged sector scan.

 

 

 

 

Attention in above two inspection method:

 

1.be sure acoustic coupling in move the probes, speed lower than 100mm/s

 

2.Moving the probe scanning along the circumferential direction, the transverse dimension should not exceed half the wafer.

 

 

 

 

Making reference block

According to the workpiece actual situation, especially selects male thread workpiece EDM, simulated cracks nature and produce section, male thread district processed 0.15 mm to 0.5 mm graded series of grooves 6.

 

 

Test result:

 

Crack 0.3 mm threaded region grooving test results about 0.344 mm

 

 

Filed test results:

 

Threaded region crack depth determination: 1.2 mm

Threaded region crack depth determination:2.1mm

 

Threaded region crack depth determination:1.8mm

Threaded region crack depth determination: 1.2mm
