Ultrasonic Testing (UT)<\/h1>\n
<\/div>\n

High-precision internal flaw detection and wall thickness measurement by ASNT Level II certified inspectors.<\/p>\n <\/div>\n<\/div>\n\n\n\n

What is UT?<\/span>

Ultrasonic Testing in Oil & Gas<\/h2>

UT uses high-frequency sound waves to detect internal flaws in metallic components and measure material thickness. Equipment can detect flaws as small as 1mm and measure wall thickness to \u00b10.1mm accuracy.<\/p>

PetroNDT inspectors are ASNT Level II certified and perform UT to ASME Section V, API 570, API 510, and AWS D1.1.<\/p>

How It Works<\/span>

Inspection Process<\/h2><\/div>
01<\/div>

Surface Preparation<\/h3>

Clean surface, apply couplant gel for acoustic contact.<\/p><\/div>

02<\/div>

Probe Selection<\/h3>

Select frequency and type based on material and expected defect.<\/p><\/div>

03<\/div>

Scanning<\/h3>

Move probe systematically, recording amplitude and time-of-flight.<\/p><\/div>

04<\/div>

Defect Analysis<\/h3>

Determine location, size and orientation of any discontinuities.<\/p><\/div>

05<\/div>

Reporting<\/h3>

Issue detailed UT report with scan data and accept\/reject status.<\/p><\/div><\/div><\/div><\/section>\n\n
