NON-DESTRUCTIVE TESTING, METALLURGY & INSPECTION DEPARTMENT |
|
AL HOTY STANGER LTD Company is offering all main NDT techniques. Three (3) of our senior staff are holding ASNT Level-III certifications and we have over thirty (30) ASNT Level-II technicians and several AWS-CWI/ CSWIP qualified staff and paint/coating inspectors.
We carry out welding procedure qualification (and have our own machine shop for specimen preparation), welder's qualification tests and chemical analysis of, not just, metals, but all types of materials. We also provide on-site production weld testing and inspection.
Some of our major clients include: Saudi Aramco, SABIC, SEC (and their various sub-contractors), and ADNOC - but no company is too small; all our clients enjoy our high standard of service. |
